GOYOJO Thermal Imaging Monocular for Hunting, 15mm Focal Lens 256x192 Infrared Night Vision Telescope with Long Battery Life, Thermal Scopes for Outdoor Night Vision Camera Telescope (15mm)

I bought this GOYOJO thermal monocular recently and I’m very satisfied with its performance so far. It works perfectly in complete darkness and makes it easy to spot people, animals, or heat sources. The image quality is clear enough for night hunting and camping, especially at close to medium range. I really like how compact and lightweight it is, making it easy to carry in a backpack. The battery life is solid and lasts several hours during night use without any issues. The different color modes are useful and help highlight heat signatures clearly. Digital zoom works well when needed, though I mostly use it at normal view. The screen is small but sharp, and it didn’t take long to get used to it. Overall, it’s a great value thermal monocular and does exactly what I expected for outdoor night use.

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.

This is a nice compact thermal monocular and decent image quality for a 256 resolution within 100 yards. The image quality really shines under 50 yards. Has multiple color palettes, but black hot and white hot are dominant in detail and softness to my eyes. Has focus which is big plus at this price range. Taking images requires a click of the button and recording requires long press. Runs on the easy to find 18650 battery and supplies good battery life. The battery can be charged externally or via usb port. Did not use wifi function, If I were to nitpick: 1) I wish the base magnification was 2+ as the 1.6 I limits the image quality at distances. With that said its good for at home diagnose or vermon control as it is. 2) The buttons are little stiff and require some effort to push. In all this is a decent starter thermal monocular and the price makes it very competitive with the competition.

# Physical construction The device fits well in hand and feels sturdy. The buttons have a good positive click and are weather sealed. For transport a carry case is included, which has some space to store accessories. When comparing this to a smartphone dongle thermal camera there are obvious advantages to the monocular form factor. Firstly this is much tougher. It will survive a drop. A phone with a camera sticking out of it won't. Secondly, having an eyepiece is a really big advantage, in the daytime you aren't competing with screen glare and at night time the light of a screen doesn't give away your location. The GOYOJO eyepiece is good, it's bright and at 800x600 pixels it looks sharp. The viewfinder diopter has a huge range of adjustment allowing you to place the apparent distance of the image quite close or almost infinity. This range of adjustment should be really helpful for people who wear glasses. The lens cap is rubber and fits securely. It is retained on a string to make it hard to lose. The string is long enough you can easily hold it and prevent it bouncing around while you move, again just very nicely thought out little details on this product. There is also an adjustable wrist tether to prevent you dropping the device. On the bottom there is a standard ¼ inch tripod mount which is compatible with almost any tripod or monopod. When unmounted the device balances well on it's nose making it easy to place down and bring up to a viewing position which is a nice touch. # Image quality The sensor is 256x192 pixels and runs at 25Hz. There is no latency and the image feels very "live" through the viewfinder. The sensor is paired with quite a large and fast lens making it quite sensitive for its size. The sensor does not need to recalibrate every couple of seconds like the Seek Thermal devices and is much higher resolution than the FLIR ones in the same price range. I have the 10mm model. The included carry case has a little extra space cut out so you can tell the 15mm version is about 5mm longer (funny that). As for color palettes the device has all the major palettes you'd expect in a thermal camera. Classic "Iron Red" being the most visually appealing and "Black Hot" being the most useful in my opinion. You also get "Rainbow", "White Hot", etc, etc. The menus on the camera also allow adjustment of image brightness and contrast. The default brightness is about one click too high for my liking but this is very easy to adjust. There are also scene modes which I haven't quite figured out yet. They appear to fine tune the image for different situations. # Sample images I've included a few photos taken with the device: cat tax, power poles, a fence in the sunlight, and some photos of the device and my reviewing process, and a screenshot of the app. The video combines a shot of a fast moving fan to show the framerate and two others of spotting and approaching a rabbit from 200ft away. Of particular interest to me is the range you can identify such a small animal at and how easy it is to see the rabbit while it is inside a hedge and completely invisible to the naked eye. The device does not have a microphone and videos have no sound. # Bonus features This thing has a freakin laser beam. It can project a red dot which is pretty accurately aligned with the center point on the screen. This allows you to make sure you are looking at the right spot even if there is no thermal contrast. Nice! # Battery life The battery provided is a protected button top 18650 battery 3200mAh from ZLY. Protected means that it has an integral over discharge board in the battery. These are the same kind you would use in a high performance flashlight and are readily available if you want to carry a spare or two. But you probably don't need to, keep reading! Powered off the device draws less than 4.4 microamps. This is far below the self discharge level of lithium batteries so it's effectively zero. (If you had a magic battery which had no self discharge you'd have to swap it out once every 83 years to keep the clock in this thing going) Powered up it's drawing 294mA on average with occasional spikes to 400mA when it moves the shutter. This should result in 10 hours battery life with the included battery! Conveniently it doesn't lose settings or the clock value when changing batteries so it's painless to swap if you manage to run one flat. Turning on additional features does increase the battery draw somewhat. WiFi adds 100mA, the laser adds 20mA, recording a video adds 30mA, if you turn the screen off by short pressing the power button you save 15mA. Really though none of this matters the runtime is excellent even if you turn everything on. Charging wise the device charges whatever battery is installed when plugged into USB (C). You can also run the device while plugged in if you need even more endurance. # App and WiFi No permissions needed for the app! This does however mean you need to connect to the WiFi network the device broadcasts manually. But this is easy. When turning on WiFi on the device it will display the SSID and Password on screen. These stay constant until you choose to change them so typing these out is a one time deal. If you are on Android you'll see the "no internet connection available" prompt after connecting the first time. Select "always stay connected" and your phone won't prompt you any more about it. From there return to the app and hit "scan". The video feed has surprisingly little latency. Approximately 50ms by my estimation. The image quality over WiFi is just as good as through the viewfinder. WiFi range is pretty good at least 30 feet with no issues. Plenty of distance to allow you to put the device somewhere you wouldn't want your head to be while you monitor from a safe or warm location. # Improvements Minor but I'd like to see a setting to keep WiFi on both at startup. The manual notes WiFi is disabled at startup to avoid wasting power. Reasonable! But with battery life as good as this I think it's fine to let the user spend that battery how they see fit especially when there is an indicator showing the WiFi state. # Conclusion This is a great device, it has none of the usability issues you might be worried about if you thought this device was simply too cheap to be true. If you are buying it for hunting I think the 15mm version is going to be worth the price difference but even with the 10mm lens you can easily see a rabbit at 200 ft in pitch black. Definitely a good buy!

Très bon produit ! Pour le reconnaissance et l’observation des animaux en milieu naturel. Mériterait un meilleur zoom numérique et il faut faire très attention aux accus car ce n’est pas des accus 18650 classiques, elles sont plus longues que les 18650 des cigarettes électroniques. C’est du +ZLY 18650.

Gute Qualität und Auflösung. Menschen lassen sich damit auch gut erkennen und auseinander halten. Die Kinder hatten viel Spaß.

Der Akku hält nicht einmal 3 Stunden , Anleitung nur China und Englisch, auf Deutsch nicht zu bekommen. Nur auf kürzeren Entfernungen zu gebrauchen , ab 50 Metern nur noch für Große ziele zu gebrauchen. Der Preis von Amazon ist weit höher als das Teil beim Hersteller kostet...

Fait le job pour le prix attention le zoom de base est un x2 et non un x1

Aún no probado por la noche pero tamaño y peso bien y acabados nivel suficiente. Es que por precio similar hay acabados muy buenos. De momento como mejorable: 1/manual e interfaces solo en inglés o chino 2/ tarjeta de memoria es interna no extraible. 16 GB debieran ser suficientes pero tal vez haya que ir salvando al ordenador y borrando del termico
