GOYOJO Digital Night Vision Scope, HD Day & Night 5-20X Hunting Night Vision Optics, 2560x1920 Resolution NV Scopes for Hunting Surveillance Wildlife Observation

This really only has one key issue and that's its weight compared to other digital optics. The housing is entirely machined aluminum which makes this extremely durable, but also very heavy at ~2lb. This will affect the handling of your rifle, although it can help counterbalance bullpups which tend to be rear heavy. This being said, as most modern LPVOs are also 2lb, you're getting a lot more capability with this optic for the weight.The QD mount is probably the best I have seen of any Chinese manufacturer. Usually Chinese QD mounts are very sensitive to the tension setting, as too much will cause it to break when the lever is closed but too lose may cause the optic to fall off under recoil. This QD uses a secondary throw lever lock so recoil can never shake the lever out of alignment. The optic also comes with a cantilever adapter which raises the height of the optic by ~0.5” and can adjust to up to 4” of rear adjustment. Note that due to the hole pattern on the adapter, you cannot adjust the optic forward. The cantilever mount is important when mounting this on bolt actions where if a bent/extended bolt handle is not used, the optic body may interfere with the cycling of the bolt. It should be noted that the screws are not tight from the factory so they should be tightened, or the optic could fall off. Additionally, the package does not come with enough screws to mount the cantilever adapter unless you only mount screws in a diagonal pattern (think like how you tighten bolts on a tire). You need to get 6 more screws from the hardware store.Contrary to what another reviewer has said, zeroing is easy. What he probably was confused about was that after entering the zeroing menu, you have to press the power button once to allow the arrows to switch to adjusting the POA. The instruction manual is clear about this. This also has a pseudo single shot zero. You use a steady rest or sand bag for your rifle to immobilize it, fire a single shot (realistically you should fire a group), ensure the POA is on the POI, then enter zeroing and you can see the old POA and your new POA as a white crosshair. Move the white crosshair to the POI, and you are zeroed. There are 5 memory slots to save zero and reticle configuration (type and color).The calibration distance setting does not change anything, it just allows you to label the zero setting with a distance which will be displayed on the screen, so at a glance you can make sure you are on the right zero assuming you are zeroing at different distances per caliber. For example, this won’t be helpful if you zero both 5.56 and 308 at 100 yards.This runs on an 18350 battery which is an odd size as it is slightly larger than a CR123A. The battery compartment is very easy to change out, however you really do not need to buy more of these special batteries as the optic can be charged while being used by a USB C cable, so a small battery bank can be mounted to the stock of the gun. Note that if you do this, you lose some water resistance and a fairly bright LED light shines from the USB plug which is supposed to remind you to keep it closed. This could be rectified by an application of dielectric grease and then RTV silicone sealant to give the male USB C cable a water resistant interface that also blocks the light. Note that if the USB cable is accidentally unplugged, the device will automatically shut off, so it is important for the cable to be securely attached if you are powering the optic externally. There is an auto power off setting, however it is disabled by default.Unlike most digital scopes, this has objective (parallax) and ocular adjustment like a normal scope. The ocular adjustment is helpful if you wear glasses and lose them as it will allow you to still see the screen clearly unless your eyesight diverges beyond the scope adjustment range. The eyebox is very wide of ~4”, so mounting on heavy recoiling guns should not be an issue. However it does include an optional eye cup which helps with eye splash from the screen illumination. The eyebox minimum distance is virtually 0 as you can use the scope body as an eye cup and put your eye right up next to it. This is obviously not advised for a gun that recoils.The screen brightness at the lowest setting is still visible in full sunlight, however contrast is significantly reduced and things in shadows may not be visible even if the eyecup is used due to the naked eye pupil constricting due to the daylight. For this reason, the maximum power is still best for daytime use. Note that the scope does not remember the brightness setting and will always return to level 6 (out of 9).The screen has three settings, color, monochrome, and green. Green does not impart a heavy shade to the image, so it is a valid option unlike in most digital night vision. Note that when this setting is changed, the brightness setting resets to level 6. This can cause temporary blindness at night with the sudden increase in brightness. Color is not a very useful setting at night because it has a mechanical IR filter which you can hear click off when switching to monochrome or green. You cannot use color without the IR filter, so the other two settings have significantly better visibility at night.The IR illuminator is part of the scope body, and although it is much smaller than most LED based illuminators, this is more powerful because it appears it is actually using a laser. The illuminator has an adjustable bezel to change the throw from a box shaped grid laser matrix, to a wide flood light. The illuminator is fairly well centered in the scope FOV which is very nice. The illuminator is slow to turn on as it turns on and off by holding the right arrow, which will turn to color mode first, then you have to hold the right arrow again before the illuminator turns on. This also means that after turning the IR light on, you will likely need to go into the menu to restore the monochrome or green setting.The PIP is easily toggled by holding the up button, and a great feature is that when PIP is engaged, magnification only affects the PIP, not the main screen. However this benefit is not well utilized as the magnification range is far higher than a digital optic is capable of resolving. Anything higher than base magnification is hard to use in low light as the noise in the image will obscure target details.The package includes a 16GB micro sd card which can be easily swapped by the user unlike most of the budget digital optics. The optic can record audio, but this can be disabled. Note that the reticle does not display in the video footage.The optic has a wifi function which can be turned off, but it is supposed to allow the optic vision to be relayed to a smartphone. However the TRVCAM program it requires is no longer present in the Play store.The best feature of this optic is the top rail. This allows you to mount a red dot which allows you to use IIT night vision to passively aim instead of having to rely on a laser. This is useful because while the frame rate is high at 50/60Hz, a red dot will not have any lag, and the high base magnification of this scope means it can be difficult to use it to shoot rapidly at close range. Note that BAC both eyes open aiming is possible with this optic which can mimic a red dot due to the center illuminated reticle, however the scope cover needs to be applied as the brightness of the screen can wash out the red POA.This scope has two unadvertised features which are fantastic additions. The first is an onscreen compass which displays the bearing of the POA very accurately and it is not tilt sensitive (which allows you to more accurately use landmarks that may be on hills or valleys). The compass is accurate, although it is slow to settle.The second feature is a tilt reading. On the left side of the screen there is cant reading in degrees which is a very useful feature since at night you typically can’t see the horizon to properly level your gun. If your gun is canted, your shots will veer off zero horizontally. The angle of the gun is given in MOA or MRAD on the right side of the screen. This reading not being given in degrees is unfortunate, but it’s easy to work into your DOPE. Having a cant reading in a precise magnitude is great for barricade shooting as it allows you to shoot tilted but with a predictable zero shift.Both the compass and the tilt readings run off a gyroscope which can be calibrated. This involves placing the scope on a properly level surface and then hitting the calibration button and waiting for it to complete. However, since the calibration setting is not saved when the optic is turned off, and the default calibration is accurate enough, it is really not worth doing.The BDC setting is a stadiametric rangefinder which is engaged by clicking the down button and exited by holding the left button. In BDC mode, you select between a deer, hog, wolf, or rabbit. Then you adjust the top bar until the space between it and the bottom bar is the height of the animal, and the range is displayed. While quick to access, this is not a very useful feature as it is prone to error since the range output does not change based on what magnification setting you are in. Additionally the size of the animals indexed may vary significantly in real life hunting. A better use of this mode is for calibers like 300 blackout where you figure out which animal setting corresponds with your subsonic zero at base magnification. Note that adjusting the top bar to perfectly match your alternate zero is not useful since when you exit BDC mode and return, it will always be reset to the height of the animal at 91m (100yards).This optic really rivals some of the more expensive digital optics that cost well over $500, and it gets a lot of things right that most budget digital optics don’t.

Very good far, the image is very chrisp and the refresh rate is very responsive. I have still yet to properly test in a field environment but just by looking down the steet at cars and all that you can see a lot of detail.This scope is nothing crazy amazing and you won't be able to identify in great detail at long range but it's perfect to help cue you on with normal glass binoculars or a normal scope.This scope would also be very good to mount to a tripod with a swivel arm and use it with your phone to help keep it steady.I have seen in other reviews that people are complaining of a clicking sound and the display freezing. This does not mean your scope is broken, this is 100% intentional and is part of the automatic calibration and you can turn this function off if it bothers you.The only downside which is minor in my opinion is the button placement it would be nicer if they had a more tactile feel to them and it was easier to tell which button you are using just by feel alone.

Very frustrating! IT CANNOT HOLD ZERO! I have taken it to the range 4 times now to get it sighted-in. Each time, I end up having to adjust it a lot. I took it off of the rail, tightened all of the screws and cranked it tight onto the rail to make sure there was no wiggle from the mount. On the last trip, I locked in at 50 yards, then checked it at 100 yards. It was pretty close so I called it good. Since I had a suspicion that it wasn’t holding zero, I decided to check it one more time. I couldn’t even hit the target at 100 yards on the last recheck. This has been the struggle since I bought it. I sight it in, call it good, then it’s way off when I try again later. I wanted to save money, but I’m actually losing money on this because I still have to buy a better unit and now I have this paper weight.

Ever since we moved to the country, we have always wanted a night vision scope, for shooting as well as just looking to see what was around our home.I was happily surprised with the one I purchased because it does so much and at the price point compared to others, it seems to stand up to scopes way more expensive.Being able to zoom to 5x, 10x, 15x and 20x is an appreciated option, although, with no sun and obviously night vision, when you get to 20x zoom, it does break down a little but reading the reviews and understanding the technology, that is to be expected.The app was easy to download and understand the simple directions.I love that we can record what we see through the scope. That is not an option with many of the scopes I looked at.Also, it fits handguns as well as the long guns. That gives a great opportunity to utilize the scopes functions more ways than I ever imagined.The battery life goes on and on and on, we have only had to charge it once so far.The only downfall is for me, it is a little heavy after a while, but that seems to be expected from the reviews on all of the NV scopes I looked at.Overall, I am happy with my purchase. It is just as described, it has so many options, it is a lot of fun just looking through and seeing what's out in the wetlands and fields.

Well, so far I loke this scope. Yrs, the instructions are not very good. But but the scope is nice. Everything I wanyed in a scope. Someone here saidvthey couldn't figure out how to set it up. Even said they had an electrical engineer trying to figure it out. Really? It's not that hard to figure out the setup and features. I recommend this scope. The only 2 things I don't like is, can't adjust the MOA for under 50 yards, but it's ok. Second thing I download the app so I can view the scope on my phone, but there isn't the option in the app to add the scope. They should remove that info from the features since it doesn't work. But all in all. Nice scope. I use it on a killer Instinct flow 415 compound crossbow, and it works great!
