Description
The GOYOJO GRS and GRL Series thermal riflescopes help you scan your surroundings, spot heat signatures, and keep track of what you see in low- light conditions. Both series use an uncooled VOx thermal sensor and offer seven thermal color palettes, so you can choose a display that suits your preference and viewing conditions. The GRS series features a 256 × 192 sensor with 12 μm pixels, NETD <35 mK at 25°C, F/1.0, and a 50 Hz refresh rate. Its 25 mm objective lens provides a 7.0° × 5.3° field of view, with 3.5× optical magnification, 1×–8× digital zoom, and 65 mm eye relief. The GRS225 offers algorithmic ranging, while the GRS225RF adds a 905 nm infrared rangefinder with a range of up to 1,000 m (1,093 yd) and ±5 m accuracy, plus intelligent ballistic calculation. The GRL series offers a choice of thermal sensor resolutions: 384 × 288 on the GRL325 and GRL335, and 640 × 512 on the GRL635. NETD is <25 mK at 25°C, F/1.0 for the GRL325 and GRL335, and <20 mK for the GRL635. The GRL325 has a 25 mm objective lens and 3× optical magnification; the GRL335 and GRL635 have 35 mm lenses and 4× optical magnification. All GRL models offer 1×, 2×, 3×, and 4× digital zoom, 50 mm eye relief, and five reticle types with five color options. Both series include useful viewing and recording tools such as picture-in-picture, hot tracking, image enhancement, photo and video capture, and recoil-activated recording. RAV and Wi-Fi app support help you review and manage recorded media. Storage and battery life vary by model: GRS models include 32GB storage and provide approximately 7–9 hours of operation; GRL models include 64GB storage, with approximately 6–8 hours on the GRL325 and GRL335 and about 4 hours on the GRL635. Weather protection and recoil ratings also vary by series. GRS models are rated IP67 and tested to 800 g/0.4 ms; GRL models are rated IP65 and tested to 1,000 g/0.4 ms. Both the GRS and GRL Series are intended for commonly used rifle setups with recoil no greater than a standard .308 Winchester or 7.62×51 mm NATO setup, when properly installed. Do not use with higher-recoil magnum calibers, such as .300 Winchester Magnum or .338 Lapua Magnum. Recoil varies with the specific rifle, ammunition, and mounting configuration.

Quality at this price is insane
Style: 256-25 Rangefinder
Definitely recommend Great rangefinder with excellent performance for the price! I’ve been really impressed with the GOYOJO GRS225RF. The build quality feels solid, it’s easy to use, and the range readings have been accurate and consistent in the field. The optics are clear, and it’s especially useful when I’m out hunting and need quick, reliable distance measurements without carrying a bunch of extra gear. What really stands out to me is the value. You get a lot of features and performance without having to spend a fortune on a high-end rangefinder. After using it in real-world conditions, I would definitely recommend the GRS225RF to anyone looking for a dependable rangefinder for hunting, shooting, or outdoor use. Great product for the money and definitely worth checking out!

Great thermal scope
Style: 256-25 Rangefinder
I’ve been really impressed with the GOYOJO GRS225RF thermal scope. For the price, it offers a lot of features and performs extremely well in low-light and nighttime conditions. The thermal image is clear and makes it easy to pick up heat signatures that would be difficult or impossible to see with a traditional optic. The controls are straightforward, the display is easy to see, and the overall build feels solid. I also like how quickly it starts up and how responsive the image is while scanning an area. Battery life has been good for my use, and the scope has proven to be reliable and enjoyable to use. One of the biggest positives is the value. You get a capable thermal optic without having to spend the kind of money associated with some of the higher-end thermal scopes. Overall, the GOYOJO GRS225RF has exceeded my expectations. It’s a great option for anyone looking for a feature-packed thermal scope that provides a clear image and good performance at a reasonable price. Definitely a piece of gear I’ve enjoyed using and would recommend checking out.

5 STAR REVIEW
Style: 256-25 Rangefinder
This thermal is incredible for the price point. I am so beyond impressed. Having a thermal starts at 1.0X magnification is so nice for the closer shots on coyotes. In my opinion the 256 resolution acts more like a 384 resolution scope. So easy to set up and mount with the included scope rings. Having an external battery and an internal battery is so nice for being able to hunt all night. I never even needed to add the extra battery while I was out hunting for over 5 hours but was nice to have in case I needed it. The one shot zero feature is so easy to use and get this optic zeroed. It stays true no matter what abuse I put it through. It is extremely durable and there are so many color palettes to choose from. The built in range finder is top notch and a HUGE selling point for me. Finding another thermal with all of these options, functionality and durability in this price range would be near impossible. I will absolutely be purchasing more goyojo thermal products in the future. They have my vote. 10/10

GRS225RF - High Performance // Incredible Value
Style: 256-25 Rangefinder
As an avid varmint hunter here in rural Missouri, I can honestly say this thermal scope checks just about every box I look for when I’m out chasing coyotes and hogs after dark. The 25mm lens paired with the 256×192 sensor and sub-35mK sensitivity gives a surprisingly crisp thermal image for this class, and the 1440×1080 OLED display really brings it all together. I’ve used a lot of optics over the years, and being able to reliably detect heat signatures out past 1,000 yards is a game changer when you’re scanning open fields or timber edges. The built-in rangefinding and ballistic assistance is another huge plus—it takes a lot of the guesswork out of longer shots, which is especially valuable when you’re dealing with moving targets at night. What really stands out in practical use is how smooth and adaptable the system feels in the field. The 1–8x zoom range and 50Hz refresh rate make tracking fast-moving coyotes feel natural, without that choppy lag you get from lower-end thermals. The AI image enhancement and multiple viewing modes help cut through Missouri’s humidity, brush, and temperature swings, giving you a clean, usable picture in real-world conditions. I also appreciate the rugged build—between recoil resistance, waterproofing, and solid battery life, it’s clearly made for long nights in rough environments. Features like recoil-activated video and real-time sharing are just icing on the cake. Overall, this scope delivers serious performance and reliability, and it’s quickly become one of my favorite tools in the field.

The most important thing to know about this scope is that it is user-friendly!
Style: 256-25 Rangefinder
So when I first opened the box, I was very pleased with the packaging and how they made sure that the scope was drop proof. Once I finally got the scope out, I started checking out all the features and the one thing that stands out about this scope is it’s very user-friendly very simple to go through all the applications between zeroing, putting in your ballistics and switching through profiles and settings, etc. The image quality on the scope surprised me because it being a 256 core. I would say this 256 core is probably comparable with AGM, RIX, and NOCPIX 256 core. The LRF is a huge win for the scope only because of the fact it is very accurate. The image quality for the scope is definitely a huge factor for a 256 core because you can actually range and identify out to about six 700 yards which most to 56 scanners or scopes you can’t unless it’s 400 yard yards or less. Overall, I would definitely buy the scope 10 more times. I have it on a few different things that I like and I actually run a lot of thermals and I am very impressed with this scope. If you want an honest review, it would be go by the scope and be impressed with everything it offers. i’m excited to see what this company comes out with next as far as a 384 or a 640 Core because then they’ll be right up there with some of these top thermal companies. Keep up the great work.!!

Awesome scope. Key features that makes it great for the money are ...It's a thermal optic Ballistic calculations,1 shot zero along with screen recording and wifi control. All features that usually only come in a high priced optic but for a very nice price. Construction feels solid and operation is very simple. If your looking for a fantastic scope but don't want to spend big bucks then this is for you.

$900 Thermal !!!
Style: 256-25 Rangefinder
Anybody who knows anything at all about optics knows "you get what you pay for" and this scope is no different. Knowing this going into researching and buying this scope is on me but what I needed it for wasn't no big deal. Honestly no more than 100 yards! The reason for the 3 Star is yes the scope is thermal and it dose work and would work mostly for what I needed it for but... I already have a $4,600 thermal scope and don't get me wrong, I'm NOT comparing this scope to my scope!!! The 3rd star is they did accept my return. With that being said I'm a big believer in you get what you pay for BUT you should also get what is advertised that your pay for!!! Like I said it's an OK scope but the images they are selling you with the refresh rates described aren't anywhere close to what you think you are buying. Without going into a bunch of detail I guess common sense takes over from here and if you do need details... well you need to buy this scope it's the one for you!

Best thermal for this price point
Style: 256-25 Rangefinder
For this price point you can’t go wrong with this thermal. This is my second GOYOJO thermal and it did not disappoint again, on choice I mounted it on was a gamo urban once you sight it in and use the ballistic calculator this thing is a tank!!! I’m able to to quietly take out 20-150 yards away. The resolution is distorted in the video due to being compressed 3 times but it looks so much like a 384 resolution thermal when you’re using it. Battery life is great was able to go for 6 hours and still had battery life left in the tank. This thermal is no slouch if your considering a thermal and have a budget this is the one for you with a LRF and ballistic calculator your going to own the night
