The G215 thermal monocular is a great budget friendly thermal spotter without compromising quality. It performs just as good as the more expensive 256 resolution thermal monoculars on the market without breaking the bank. I have opted to mount mine on a golight making it remote controlled from inside my vehicle by watching it live streaming on my tablet. This is great for those cold nights checking the fields for hogs. No more having to roll the window down and lean out the truck. I can now see 360 degrees around my vehicle. Identification range between deer or hog is about 250 yards. Detection range of a deer or hog is about 500-600 yards. The battery life is really good and will last all night of hunting without being turned off. I would highly recommend this optic to anybody new to thermals or that doesn’t want to break the bank but wants a quality monocular.

I've tried a high end thermal scope, and a budget phone-connected thermal imaging device. This Goyojo 15mm falls right in the middle of that performance, but with a price much closer to the budget device. The clarity on this is very good and compares to devices that cost twice as much. I use it exclusively for locating wildlife in unpopulated areas. It is sensitive enough to pick up a songbird sitting on a limb 100 yards away. As my purpose is to simple locate wildlife, I have found that red hot mode works best. It immediately picks up any heat relative to the surroundings. The attached images are single deer, located at 80 yards (feeder) and 50 yards (trees). It powers up quickly. The battery life is great. It has a setting to automatically turn off after a specified period of time (which I set to 10 minutes) so that if you leave it on it won't drain the battery. It takes pictures and video, and it's easy to pull these to a computer with a USB C cable. It does support WIFI but I found that a bit cumbersome to use. I have recommended this product to my outdoor enthusiast friends who are interested in thermal and locating wildlife.

As someone who hunts often at night, I was honestly impressed by how well the GOYOJO Thermal Monocular performs for its size and price. The image quality, even though it’s 256x192, is clearer than I expected and makes it easy to pick out heat signatures from animals, brush, or even small movements in the distance. The 25 Hz refresh rate keeps the picture from feeling choppy when you’re scanning across a field or moving through the woods. The 10mm lens gives a nice, wide view, which is great when you’re trying to locate game without constantly swinging the monocular around. It’s lightweight and comfortable to hold for long periods, and the buttons are simple enough that I can operate them without taking my gloves off. The menu is straightforward, and switching between color palettes or adjusting brightness is quick. Battery life holds up well for several hours of continuous use, which is important on longer hunts. What I like most is how it helps me immediately tell the difference between an animal and background clutter, saving me time and helping me track more safely and effectively. It’s not on the same level as high-end thermal scopes, but for everyday hunters who want reliable night vision without spending a fortune, this monocular delivers a lot more than you’d expect.

The media could not be loaded. One of the best things about this product is that the listed weight is not correct. While Amazon lists the weight as 2lb, that is only for the entire package which includes a hard case that comes with it. The actual monocular only weighs 12oz with a battery, making it suitable for helmet mounting which dramatically increases the utility. It has a tripod screw which means a 3D printed mount can be printed for this for helmet mounting. It also has a USB-C connection on the side which can be used to power it to a battery pack counterweight, however the battery replacement is very fast and easy and the runtime of 5 hours, makes this not necessary unlike other cheap monocular. There is an auto shutdown mode, but this should be turned off as the maximum time is only 30 minutes. The biggest issue with this monocular is that it lacks an objective focus even though it looks like it does. It is focused to infinite from the factory so its not really a practical issue unless you are using this for close up work such as diagnosing electrical circuits. This does have ocular focus adjustment, however the range is very small, so it is best left turned all the way counterclockwise and forgotten. There is no eye relief to speak of, so the FOV is dramatically reduce if wearing goggles. Base magnification is not true 1x, it is closer to 1.5-2x base, so the thermal image will not collimate with your vision. The magnification steps also does not seem to be accurate, with 3x being the true max magnification. The color palettes are the traditional white hot, black hot, red hot, and two fusions, but a unique palette that I have never seen anywhere else is "glimmer" which is a green tinted white hot. This is great if you are mounting this monocular to bridge with an IIT NVD with a green phosphor tube, although the benefit is somewhat negated due to lacking true 1x magnification for collimation of the images. There is an option in setting called scene mode which is supposed to help reduce static noise in the image based on certain environments. I would stick with the standard scene mode as city mode makes it slightly blurry, jungle darkens the screen significantly, and custom adds static noise which is counter productive. A really cool feature is an integrated red laser which allows you to point out objects to others. It would be ideal if it was an IR laser, but it's still a useful function. Although the optic for the laser is not great as there is a divergence with a secondary beam that shoots off 45 degrees from the main beam. When red laser is activated a reticle appears on screen which can be zeroed and changed between 6 different types in the settings known as "dividing line". This function means this monocular can theoretically be weapon mounted with a camera rail mount adapter. It's not designed to do this based on the instruction manual, but it could be a nice option for airguns, airsoft, and 22LR. The laser cannot be turned off when the reticle is on so a piece of electrical tape would have to be used to cover up the laser. This even has a PIP (Picture In Picture) function however strangely it can only be placed in the 4 quadrants of the screen in the settings. It cannot be placed top or bottom centered which is a big oversight. In the settings you can change the NUC (sensor refresh) from automatic or manual. The NUC is not nearly as aggressive as other monocular so auto is best. It also has a bad pixel correction feature where if a pixel on your screen is off and isn't fixed by the NUC, you can manually select it to correct it. This can take pictures and video and also view them. Video file sizes can be adjusted based on time, they should be set to 30min files for best uninterrupted footage. The SD card is internally fixed so it cannot be increased without taking apart the monocular which the screws are accessed by pulling off the eyecup. However there could also be a software block on maximum supported memory card size. The 16GB capacity is pretty good though, and you can see the exact free space on the card in the settings. Screen contrast and brightness is adjustable and I have found 5 contrast and 3 brightness to be ideal. This has a hot spot detector which will highlight the hottest spot on the screen, however with good brightness and contrast settings you should be able to naturally notice the hottest spot just as fast without the detector highlight. This can stream video by WIFI which can have a custom name and password. However this also has the ability to stream the video feed through a wired CVBS screen as well. Which is potentially useful in situations where a smartphone should not be carried and sending out wifi signals could be dangerous. Video clip in this review represents an extreme target condition of a cat laying down at 100 yards. This is roughly equivalent to a human at 700 yards.
