Top 10 Best Thermal Scopes (Mar. 2020) : Review & Buyer’s Guide
- Erik Himmel
As a ship Captain, I had in my custody night vision binoculars to detect the presence of Somalian pirates when crossing the infested waters off the African East coast.
A couple of years back, I was sailing a ship, a brand new delivery from Rotterdam to Asia. The passage transited the Piracy Zone. This time we had armed guards on the ship. At night, the Commander of the guards was showing me their firepower including a thermal scope. I took a look at the deck through the scope and jumped back in disbelief. There stood a man on the deck in stark relief. No, it was not a pirate but one of the ship hands on deck patrol duty. The clear, lifelike image stays with me till today. Thermal scopes detect heat-emitting bodies such as animals or persons. So, if hunting is a passion of yours or you need to do away with marauding animals, invest in the best thermal scope you can afford. To choose wisely, you need to be well versed with the product, what is on offer, the costs, the pros and cons, its use, care, and maintenance, etc. This article aims to educate and update your knowledge about thermal scopes.

Our Top 10 Best Thermal Scopes List
This list was curated after a great deal of study into the various modes and makes out there in the market. User reviews have been combed for their inputs into the pros and cons of various models. Based on what we found, we have compiled the section Things to Look for in a Thermal Scope. As each scope has its distinctive flavor, our Top 10 Product List features those models in greater details.
The Pulsar Trail XQ50 2.7 comes with high base magnification, with thermal imaging and precision positioning at incredible distances. Having a high refresh rate of 50Hz, the images provided are fluid, top-notch. With a 640x480 ice-free AMOLED display, it is able to detect heat signatures in the active detection ranges, on the longer side being 1350 to 1800m. It encompasses multiple zeroing profiles as also 10 electronic reticules. The additional feature of a Stadiametric rangefinder makes acquiring the target simple. It boasts three operating modes; City, Forest, and Identification. The external battery pack, extends the life to 20 hours. The design is both functional and ergonomic. It sports a user-friendly interface.
The option for three different zero calibration is available on this scope individually for the three different Modes City, Forest, and Identification.
After having tried out the XQ5o and XQ38, we tried out both the models first.
We were won over and impressed by the ease of use.
The UI is clean and the design is intuitive, with an unbelievably clear image along with the means to tweak contrast and brightness on the fly.
Full marks to the absence of any lag for quick scanning. The picture-in-picture feature renders hog hunting a song. Take shot, pick next, take shot. Nailing hogs running at full speed is no easy task. Many optics don’t fare so well, have a jumpy image, sway or glitch. The Pulsar XQ50 image processing is second to none for the money.
When we tried out the 50 and 38 for image clarity, they turned out basically the same. The objective size, field of vision and magnification are correlated. Smaller objectives will have a less base magnification and a greater FOV at short distances. Larger objectives have a larger base modification and a greater FOV at short distances.
Another of our experiences with the QF is that the built-in rangefinder which determines the range based on the size of the animal tends to be inaccurate as compared to laser ranging.
We also did try it out in different weather conditions; fog, rain, sleet and snow, without a glitch.
Everyday Joe can now get his hands on professional quality imaging.
Our unanimous decision to crown the Pulsar Trail XQ50 as Overall Best was propelled mainly by its ‘no-nonsense’ attitude. The configuration of sensors, components, refresh rate simply unearth the target even in the densest of cover, place the target well etched, in sharp contrast and early enough making it a child’s play to nail it. This is a phenomenal quality scope. Period.
ATN’s Obsidian IV Dual core boasting nextgen Thermal Sensors powers the ATN ThOR 4. Its heightened thermal sensitivity, enhanced contrasts, smooth shutter, and boosted resolution makes the refurbished ATN 4 user-friendly and swift to learn.
Your shot will count every time and hit the target. The Ballistic Calculator- Target Angle, Temperature, Humidity, etc., are factored in for those professional long-range shots
The ThOR 4 is capable of Dual Stream Video Recording; to your smartphone and simultaneously the SD card.
The RAV automatically starts to records prior to and after shooting.
Our experience with this optic has been just great. Agreed, it takes a while to get used to the menus and the unit is on the heavier side, but it is a well-built piece of equipment.
We were much endeared of the one shot zero function. It is a game changer. Now you don’t need to shoot half a box of ammo to get it perfect.
Most users we spoke to were absolutely enthralled and so are we. The clarity is crystal clear.
After adjusting the settings taking ambient conditions into reckoning, we could spot deer at 500m clearly.
This optic maintains zero without wandering off.
We tried out the mounting by siting it on the 450 Bushmaster and a 300 AAC. It was a simple exercise and moreover, the 300 AAC was stored when the mount was shifted back to the Bushmaster.
As is sometimes the case, a few complaints were regarding tardy customer service offset by eulogies regarding the service.
Also nothing unusual in this, but we found it gets a bit blurry when zoomed all the way.
Overall this is an impressive optic and comes highly recommended.
One thing you should not forget is updating the firmware regularly.
This one earned our Budget Pick medal not because it is inexpensive but for the huge array of features on offer for the money. The large range of selectable reticules and the panoramic display with the option of going two-tone is enthralling. Its performance in inclement conditions be it the heaviest rain, or dense fog, the target is detected with great ease and is a sitting duck. It is designed for heavy-duty and the range of add-ons leaves nothing to be desired. This high-tech, low maintenance optic is one of the best in the market today.
The ATN ThOR HD 640 pushes innovation to the 21st century. It has particular night vision capacities. The ATN ThOR HD 640 Smart Thermal Riflescope runs on an Obsidian Core which can crunch immense records without breaking a sweat.
This thermal scope doesn't inconvenience you with complex outlines, mini-computers, or reticles. It is the simplest extension. The ATN Obsidian Shooting Solution deals with all the intricate estimations.
The Recoil Activated Video records the video as the trigger is pulled. The rangefinder does practically everything for you almost the same as rangefinder binoculars. Just point on the objective to get the vital readings. The degree highlights astonishing ergonomics and accompanies an E-Barometer, Gyroscope, E-Compass, and Bluetooth and WI-Fi included as well.
We took time out to get a firsthand account of this scope and our first finding was that take the time to read the manual and practice a bit. It is everything the manufacturers claim it is.
Another thing instantly evident is the 30 Hz processor. It does not track moving targets well enough and also presents ghost images. As expected it’s really not fast enough for moving targets. Do go in for the 60 Hz processor.
We tried out a 3 year old model without the gimmicks the new ones come with and came away blown over with its consistent performance; it functions perfectly for regular deer and hog hunting. The view was clear, bright and adjustable. It turned out to be amazingly sturdy without damage or degradation in quality of viewing. The reticle holds true when dismounting, mounting the scope for cleaning.
Another noteworthy discovery of ours is the huge price differential now. It’s a $1000 less than at that time.
Another observation of ours is the superior night vision of this optic. Also the number of features on offer can be a bit overwhelming at first but once familiar, it’s a real beaut.
We give it 5 stars hands down. This thermal scope calls for a bit of reading and some practice to perfect it. The WiFi gives others the opportunity to share the experience by viewing the action on their smartphones. Another feather in its cap is its durability. We found it can withstand a fair amount of beating. With its innovative technology and the goodies thrown in, our Good Value for Money award is not misplaced.
ATN Thor-HD 348 is a soperb thermal rifle scope. Smart HD Technology puts this scope on a different platform than the competition. .
Recoil Activated Video (RAV) permits recording all your sessions.
The rangefinder is built-in will make things easier. It calculates distance, so a perfect shot is gauranteed every time.
Recording your forays is a simple deal using the SD card without the need for any extra USB cables.
Our take is that it is a great scope for short range game.
Much the same as with the durability factor, the 384 and 640 have basically identical extras; Video modes, Wi-Fi, and streaming are a part. The ballistic calculator and smart rangefinder are mirrored. Truly, the main contrasts here that can be an issue is power. If you are within normal shooting distances, the ATN HD-348 is your buddy.
When comparing the contrasts between the 640 and the 348, we found the 348 lagging a bit it came to the cost. To save money and still hunt for a bargain in getting a sturdy, usable optic, you should home in on this scope.
Contrasts are absent between the two siblings with regards to sturdiness. It can deal with the entirety of harsh conditions and temperatures. They won't haze or be harmed from water and can deal with impacts as far as possible to the biggest non-magnum ammo.
We tested it in daytime when it was rather hot, the paper target was vividly visible after 30 minutes.
We did notice some very minor screen interference with the WiFi. Also spectacle users found the eyecup design requiring one to remove glasses.
We found this to be an excellent choice for beginners. The Smart Thermal Riflescope lives up to its image and truly is extremely well suited for hog and coyote hunting besides other vermin and foragers. This best thermal scope for hunting comes with a host of extras and for its price is a real performer.
One cannot but embrace this best thermal optic made by Trijicon. They make the best thermal scope despite their late entry into thermals.
The REAP-IR is made to military specs and comes with the new stadiametric rangefinding technology providing a 12° degree field-of-view lens.
What makes the REAP-IR ideal for military, security, and night hunters? The 2.5x magnification coupled with the 640x480 resolution and a whopping 60 Hz frame rate. A target, no matter how swift stands little chance against this lethal combination.
It is also the most robust be it desert conditions or those of urban streets.
Extras were not a predominant design concern but the Reap-IR has a few handy ones chief among which is the integrated rangefinder. This is linked to a readout reflecting where the reticule is pointed.
In our quest for understanding the performance, the first thing that struck is the versatility.
A bonus is in the choice of just outlines highlighting targets so that your night vision is not messed up. As a dedicated weapon scope only, it cannot be used as a clip on.
What we feel is a major setback is that the controller thumbstick is positioned not on the top but to the right, a huge disadvantage for left-handed shooters. It is also over-sensitive making it difficult to choose an option correctly.
About the much touted picture quality, we saw for ourselves that it was indeed crisp and clear to perfection.
Our disappointment was the trade-offs to sacrifice weight. The focusing ring was done away with and you can’t get a sharp image closer than 5 yards.
The second drawback is that there is no internal shutter. Recalibration of the thermal sensors is required frequently as the unit warms up or cools down.
The use of small CR123 batteries is limits use to 3-4 hours.
This is a foregone conclusion. User reviews we got were all out overwhelming in praise of the Reap-IR. Shipping was quick and performance promises all held up. The image quality is exponentially better thanks to the 60Hz frame rate, a fast-moving target poses little difficulty. With so many features packed in, this is one can’t do without scope.
This Thermal Imaging Scope can, be it day or night, pickup and recognize your prey.The ATN core performs superbly. Utilizing the amazing Obsidian Core & UI, the ATN ThOR-HD is designed to operate as a state-of-the-art computer. Throw in a ballistic calculator which compensates for the trajectory of the bullet. Feed your wind readings to the Smart Range Finder and the Core leaps into action. Armed with RAV and a smart rangefinder, you can use this scope for taking down big game in low light conditions.
Our research dug out that the mounting method is a poor choice. The focal lens sits too low to get a good sight picture without resorting to an awkward angle. The natural sighting looks at the bottom right corner of the internal screen. This was tried using the same mount on four different rifles with the same result.
It was appalling to see the quality of the packing case which was merely a cloth satchel, hardly befitting for a $2500 optic. Also the serial number is an affixed sticker which will disappear in a few months and then you are in hot water to make warranty claims.
The menu can swamp you unless you are using it a lot.
We also saw that recalibration is necessary frequently.
The factory mount is poorly made. We recommend to replace it with a ‘return to zero’ picatinny mount that works wonders.
The NUC process which recalibrates the image to compensate for changing environmental conditions, needs to be done frequently, which though annoying, is quick and easy to do.
Everything works as advertised. The image is outstanding, crisp and clear though some users have a complaint here. This robust device can handle heavy, harsh conditions without a whimper. The first time set up may throw you off but you are ready for takeoff once you have your profile and zero. So, head downwind and engage those boars instead of merely spooking them. Prepare your gear and grab the best thermal rifle scope without further dilly dally and nail those pests
A List of 4 Other Products We Reviewed
FLIR’s offering in thermal optics of today is the provision of the most explicit and crisp imagery. It has the ability, be it by day or night, to zero in on your targets. The clarity and image quality of this low cost thermal scope which is boosted by the ultra-fast 60 Hz refresh rate and completely eradicate pixelation. This affordable, compact scope is a perfect fit for deer hunting, scouting, and even professional use.
Even at this budget price point, it can record 2.5 hours, that is 1000 images, is possible accompanied by multiple color palettes and reticle choices. The range finder comes built-in. The best part is the lightweight scope, under 1.5 pound.
The aluminum aircraft-grade compact housing shields a FLIR Systems Boson core with a pitch sensor. For enhanced situational awareness, it has an industry-leading on-chip video processor.
We found this optic amazing all round. Target detection through smoke, haze, fog or rain. Absolute clarity on a high-resolution display.
The integrated digital compass and inclinometer guarantees precision range and target orientations.
Our research finds that FLIR has upgraded this model to a 60 Hz processor making it formidable for fast moving targets.
This scope too has one drawback in that it crams in a lot of features. Not that this affects performance, only more time to read up and understand.
An oft repeated grouse was the poor documentation in that not well explained. Hopefully the manufacturers are taking heed of this as a proper manual is a huge necessity.
A more serious drawback is the all too frequent freezing of the system requiring restarts.
The view finder appears very narrow and the field of vision very small. Enhancement of eye relief too is wanting. Image quality is a little wanting at higher zoom levels but that is expected.
This is the cheapest thermal scope in the market. Some users have had issues with image clarity subsequently set right by FLIR under warranty. Truly that is an exception rather than the rule and we are open-mouthed at this mind-boggling feast of features for the money being shelled out. This scope is well suited for hunting, scouting and even professionals vouch for it.
The civilian market is the primary target for Pulsar thermal scopes. The high-end features that Pulsar incorporates on their flagship models vis-a-vis contrast presets, picture-in-picture zoom, external power supply capability, 50 frames per second, one-shot zeroing, and a range finder, built-in. The 8x zoom gets you on the target in a flash.
A unique, distinctive feature of the Pulsar Core RXQ30V is the presentation of heat signatures in a green sapphire tint. A 50 Hz refresh rate with a 640x480 AMOLED display delivers high-resolution thermal images. This optic reveals three modes of operation; forest, rocks, and identification to guarantee peerless pictures for your environment. Human-sized heat signatures at 900m are unveiled by the glass-nylon composite Core.
What we found on inspection is there is no recording facility. There is no practical way to adjust elevation. The zero is fixed. However you can choose a reticle.
The battery pack itself is not a standalone power supply. The equipment comes with an adapter that fits the battery pack. The two batteries will last around 5-6 hours.
An amazing optic. Can see targets clearly up to 200 yards. However reticle doesn’t change color when hovering over a hot object
Some users claimed screen freezes but that is due to improper sensor calibration. It has three modes; Off, Manual and Automatic. Keep it on manual and all problems should go away.
We also discovered that newer models have dumped the sapphire tint and reverted to black and white. Further investigations revealed that users have found the green tint bothersome.
We probed for how much recoil can it take and found it was rated for 6000 joules which is quite a lot.
The thermal scope mounting is good we discovered as long as it has a picatinny rail, will fit on any gun.
For the price, this optic qualifies for the cheapest thermal scope hands down. We, however, find no cutbacks or compromises in the product. In fact, it is a marvel how the bundle of goodies remain undiminished. A point in question, a 50 Hz refresh rate. Let’s not waste time, go fetch yourself the best thermal scope before stocks run out. Simply a stellar buy.
Sticking the traditional riflescope, standard 30mm ring, and scope mount platforms provide the perfect mounts for The Pulsar Thermion. Utmost durability to IPX7 waterproof rating (can withstand submersion in 3 feet of water for 30 minutes) and a housing of magnesium-alloy provides rugged and well-founded, all-round performance. From under 1000 yards away, it renders perfect heat-signature imaging on a full-color 1024x768 HD AMOLED display.
The resolution is 320x240 with 12m pixel pitch, PIP, 8 color palettes and 15 reticles. Audio is blended Integrated still image and video recording with Pulsars Stream Vision App. A magnification range of 3.3-13.2x and a 50 Hz frame rate is a game changer. .
The refresh rate is awe-inspiring and you’ll be spoilt for reticle choice. The recording is recoil triggered and hassles free. In comparison, other optics pale.
We all unanimously agreed that this scope gets you the biggest bang for the buck.
It has internal recording and one of the two batteries can be removed so that the battery can be changed without the scope turning off.
The mounts offer great leeway. Anything with 30mm rings can be used. You are not restricted to one or two options only.
A word about the scope. It is sighted in for long-range shooting with unreal clarity for a 384 sensor. The digital zoom imparts a highly comfortable magnification level for both hunters and target shooters
It is quite durable and we tried it out in close 100% humidity without a glitch.
We agree that from functionality, to accuracy, to weight, it is top of the shelf.
For once, finding faults failed us.
Very hard if not impossible to get for your dollar. This thermal scope review is heading only one way. This mouth-watering spread of sheer functionality, high performance and quality have us spellbound. Beating this package in an optic is light years away for the competition. A great show, a stellar product.
Pumped by Dual core ATN’s Obsidian IV next generation thermal sensor, the ThOR 4 is unmatchable when comes to accuracy under pitch-black darkness. ATN introduced improved thermal sensitivity in this particular scope that brings better contrast and higher resolution. The noiseless shutter makes the hunting game more interesting.
We found the scope to be of a traditional design yet packing cutting edge technical wonders e. g. the ABL laser can superbly pinpoint long-distance targets and channel the data to a built in ballistic calculator using Bluetooth. That does all the reticle POI adjustments within a matter of seconds. The whopping 20000mAh battery pack provides enough juice to run the device smoothly for 22 hours. Perish the thought of misplaced chances due to drained batteries.
We were simply bowled over with this optic when testing it. It has plenty of refinements that work both for the beginners and pros.
We couldn't but love the remote controller labeled as ATN X-Track. The name is suitble because it does give you the options for tracking the rangefinder and ballistic calculator. What's more, the ATN Quick Detach Mount helps you to manage the profile of your scope easily.
There's a superb Dual Stream otpion for video recording and once recorded, the files can be easily be streamed to smart phones in HD. You can simulteneously save the video to an internal SD memory card.
It's a super intuitive device and we were able to learn how to operate it fast. ATN offers 3 years warranty for this device.
In the world of thermal optics, it is almost unheard of that the battery can last 16 hours of uninterrupted service. This is definitely ultra-low consumption. The recording directly into a MicroSD card is another welcome innovation. The ATN ThOR 4 has stolen our hearts and we heartily propagate our findings as the optic to watch out for.
Why Do You Need A Thermal Imaging Scope
Thermal Imaging Scopes find application in a number of fields.
- Operations concerning Military
- Enforcement of Law
- Observation of Wildlife such as for census
- Target Surveillance
- Concerns regarding Security
- Navigation in piracy infested waters
- Detection of Hidden-objects
To be one up on the game of their choice, quite a few hunters are looking up to thermal imaging systems. Most predators are nocturnal by nature. In this scenario of darkness, for successfully hunting them down, one should be able to see through the dark.
In many states, wild hogs have become a nuisance. States encourage hunting them and the limit on hog hunting is raised. A regular hunting scope fails in certain conditions like coyote hunting, hogs hunting, hares hunting and more. To successfully bring them down in dark, you need to be suitably equipped with the best thermal scope to boost your abilities by allowing you to get close enough to your quarry undetected. Vermin eradication is another big ask. Coyotes steal foal and small livestock, hares devastate vegetable gardens. Coyote hunting and shooting down hares need thermal hunting scopes.
Budget-friendly options do exist, but research thoroughly before buying one as the less expensive options sacrifice some features or capabilities to snip costs.
If you are an avid hunter, it is worthwhile to invest in an affordable thermal scope. These can be used by day where natural conditions like fog can conceal animals.
Are you going to be hunting in thick brush or where fog is likely to be encountered? Thermal scopes work best in these surroundings.
If temperatures are close to freezing, this affects the amount of radiation. Night vision scores better here.
If you are hunting in a mountainous area, where the light is diffuse, thermal optics fit better.
Overall, thermal imaging scopes work in both day night conditions, producing images by tracking residual heat. They are expensive, heavier, produce less clear images. In low temperatures, image quality is compromised.
Types of Thermal Imaging
Un-cooled Thermal Imaging
A cryocooler is a device that lowers the temperature of the sensor to cryogenic levels. This eradicates thermal noise levels below that of the signal from the scene imaging. Simply put, in un-cooled thermal imaging, the imaging sensor does not require cryogenic cooling. The detection system relies on a microbolometer, a built-in chip with a large temperature coefficient. On-scene changes in temperature are detected, converted into electrical signals and processed into images.
Uncooled sensors are designed to function in the same wavelength as that of the temperatures related to infrared energy released by terrestrial targets. Uncooled cameras work uninterrupted for longer periods. They are unsuitable for long-range, exceeding 5 km.
Cryogenically Cooled Thermal Imaging Systems
Cryogenically cooled systems have the imaging sensor integrated with the cryocooler that cools it down to 0℃. They are ultra-sensitive, picking up minor temperature variations. When it comes to long-range use, they are well matched. Brilliant image resolution results. Also, their thermal contrast is high which means that they can detect targets even if the background is close to the target temperature. The flip side is that they are very expensive and need servicing every 2 years.
Things to Look Out for In A Thermal Scope
Thermal scopes are indeed not inexpensive. That is because they are a specialty item. The demand for mass production of the microbolometer sensors isn’t there. The components used embrace high-tech and the value could be brought down if high volume production was viable.
Magnification power in thermal scopes can range from 1x to 16x and greater. Thermal scopes have a reliability range of 300 yards, so a magnification power greater than 3x is somewhat redundant. Keep in mind, the more you zoom, the smaller the field of vision gets. Digital zoom can cause less clear images. Figure out how far you plan to be shooting and the picture quality you desire. You can then determine how far your magnification needs to be.
The paramount features of a thermal scope are the screen resolution and refresh rate. Never matter how great your sensor is or how far your zooming capabilities are. Your scope will be rendered ineffective if the image is not crisp and clear enough.
Higher refresh rates and better screen resolution will output clear, crisp images. Carefully select your scope bearing in mind the quality of the image presented.
Range and magnification go hand in hand. The thermal detection array’s sensitivity can detect thermal radiation at fair distances. In this way, you can see your target approaching whilst you get into position for a good shot. Most scopes can give you a range of 1000 yards and above, a moderate scope around 300-500 yards. Most hunters will settle for either since taking a shot at 200 yards is the norm, are a surer shot and a night hunting safety precaution.
Guns are for outdoor activities. That means they have to weather the elements, dust, and anything that the environment can throw at you. Thermal scopes are high-tech and as such cannot take a beating. They demand care. Rough handling, banging them around is not a good idea as precision parts inside the housing could get misaligned in the process.
The best thermal scope need not necessarily be the most expensive. Understandably, Thermal scopes with rangefinders, inclinometers, and GPS are acceptable. The desirability of Bluetooth and Wi-Fi to stream to a smartphone is your choice. Only weigh the extra cost you will be incurring.
A very useful extra is the bullet drop compensator (BDC). Your rifle is zeroed for a particular range, typically 100 yards. The possible drop in the bullet for that range is compensated for when you fire. Suppose your target by your estimate is 300 yards away, just aim using the 300-yard reticule and press the trigger.
Battery life is usually restricted to 5 hours and above. Some operate on disposable batteries and some can be recharged.
Refresh Rate (30Hz Vs 60Hz)
The refresh rate as pointed out earlier plays a pivotal role in the image quality delivered. Most of the thermal scopes available in the market fall under the 30Hz or 60Hz category. The figure denotes the number of times the image is refreshed in a cycle. The higher the refresh rate, the more lifelike is the image. It is therefore recommended to go in for a scope that provides a higher refresh rate.
Thermal Imaging Hunting Tips
- The cardinal rule of hunting is to hold your shot. Most of us give in to the excitement and enthusiasm and press the trigger. This has sometimes cost dearly. It after all only takes a second to get your identification of the target correct and that it is a critter or a varmint you are seeing through your scope. Go for the trigger then.
- You need to give yourself a little time to set up your optic, It has to warm up, calibrate itself, you need to make adjustments for wind on the Ballistic Calculator, etc. before you pull on your boots.
- Make use of your smartphone by streaming your view onto it. It acts as a second pair of eyes and is also a cross-check to verify your observations.
- The Law. Be well versed with laws governing hunting. Is it allowed after dark? What can you bring down? Not all animals are allowed to be hunted. What is the bag limit applicable? Laws also vary from State to State.
- Check your zero regularly. That one single parameter sets up your device. If it wanders off, bring it back or your efforts won’t pay.
The above compilation is the result of research, analysis of the views of various users, and technical inputs from various manufacturers. The immediate purpose is to provide the reader with a detailed, thorough and comprehensive guide to steer them into making an informed buy. For example, the Reap-IR seems to be a jack of all trades, the ATN ThOR 348 especially for hunting and so on. But readers should invest their time in reading up more and objectively arriving at their choice. Engage other owners for first-hand tips and pointers.
