BESTSIGHT Night Vision Scope,DIY Night Vision(Day and Night),Quick Installation Barrle,5" Display Screen with 5w 850nm Infrared Illuminator,View 200m in Night,for 38-44mm Eyepiece Scope (TMNV01P)

I was very skeptical of this product due to its low cost. I initially looked into two other similar units after watching ratting videos on YouTube but I could not find distributors for them, at least none here in the United States. At the time I ordered the Bestsight I had been involved in attempting to rid an area of an extremely intelligent rat and using a night vision unit was the last option. The night before the Bestsight arrived I was able to eliminate said rat with my Air Arms 510 pellet rifle and illuminated reticle Meopta scope but it was just as much due to luck than anything. At the time of this writing I only have access to a distance of 20 yards here in the city for testing but here's what I found: My airgun rig consistently holds one-hole groups at 20 yards. The rifle was zeroed with just the scope using 9/16" dot targets. Then I installed the Bestsight. It was tested at night in complete 100% darkness as both the firing point and the target were inside buildings and there was no moon or star light. Without the illuminator I could see absolutely nothing. The illuminator was turned on and I could clearly see my dots. Firing several groups resulted in ragged holes with no shift in impact point. Just for kicks, the next day, I used the Bestsight to shoot groups in the daylight to see what would happen. I had to turn the magnification of the scope up more than at night for some reason but the ragged hole groups were in the same spot. My rat problem had been eliminated so I haven't been able to use the Bestsight for that application yet, but I am confident that when the next one comes along the Bestsight will be up to the task.

GARBAGE - Great concept, terrible delivery.CONS: There were several issues with the kit I received.1 - First, right out of the box the instructions are in poorly broken EngRish. It was easy enough to figure out but if you're going to butcher the instructions don't even bother sending them.2 - Second, the scope adapter rings that they send didn't tighten all the way on the scope, so the mount was unstable. I was able to stack the rings together to make it work but it still moved around more than I wanted it too.3 - That would've been ok if it would actually work at night, sadly it does a poor job. That brings me to number three, poor night performance. Since the only reason to buy something like this is to use it at night you would kind of expect it to work at night, right? Well, the truth is its only good for about 10 yards in front of you, anything farther than that forget it. The way they have the IR light setup in the pictures will not work. If you mount the light on your scope the IR washout from the flashlight creates a glow in the scope that is so bright you can't see the redacle. The only way to get it to work is to mount the light somewhere else. Even then, the range is pathetic... maybe 50 yards..maybe. I even tried a brighter IR spot light that I bought somewhere else.. it was better buy still pretty terrible.4 - Camera malfunctions? The camera itself had issues with cutting in and out (which I wash eventually able to eliminate with all new batteries, also reminds me to mention batteries) and after a shot the screen would get significantly dimmer and never return to normal with out removing the batteries. I was shooting this on an air rifle too so its not like the recoil was so severe that it over-rated the camera parts. So between not being able to see through the scope from the washout and trying to focus a dimly lit it was a constant chore just trying to see through the scope enough to focus.5 - The batteries - it takes 18650's, not included. I must have completely spaced this since I though it would take regular AA's.. it doesn't. You'll need to grab a set of rechargable 18650's but I caution you.. not all of them are the same. I had several different brands laying around and not all of them fit into this batter fixture.PROS -1. works well at short distances.2. adjustable camera focus - i was surprised to learn that the camera was adjustable. I was able to focus on the target or the redicle based on the camera focus.3... sorry thats all, I'll be sending this back.

A good value- as one military veteran reviewer wrote. This DIY night vision camera/IR set up is great for the price. Enclosed directions are visual, not much written. Best directions can be found on YouTube. Installed this system on a Bushnell 3x10x40 scope.9 inch scopes are too short to accommodate the IR flashlight clamp in front. Kit includes two camera tube fittings. Used the two-threaded ringed screw-on tube that fits over the eyepiece in back. Note: it will make your scope longer and heavier. The other is a hollow piece held in with six screws, but risks scratching the scope eyepiece unless you wrap it with the enclosed tape. The 18650 lithium batteries must be ones with flat positive buttons on top- the ones with higher buttons won’t fit the video screen battery tray. Video screen is straight forward, with menu and increase/decrease buttons on back. Choices are brightness, contrast, saturation, language, and reset. Make sure to rotate/focus the camera lens to your scope by slipping your fingers in the tube access holes to turn the lens. You also have to adjust the tube fitted over the eyepiece to center the crosshairs on the video screen. You’ll learn this system by playing with it. Observations during first rat night hunting: turned everything on, adjusted scope focus, used other switch located on back of the camera tube- it gives two positions of black/white or a light green tint. Found that the green screen was less grainy, had better focus. Unit won’t work in total darkness- even with the IR flashlight on. Had to position a low beam lantern nearby to see my baiting plate. It’s a trade-off deciding how much light to shine nearby to enable seeing your target vs scaring rats off. But when focused on plants with my back yard night lights on, the system was very good and clear.Didn’t get any takers for the cat food bait that night. Some reviews report ability to see the rat’s eye reflections during use but not possible in my case. Perhaps hunters in a place with rats galore will have a different experience. If you like video/IR setups then this kit is for you. Haven’t tried this system during the day, but it looks pretty straightforward.I plan to test a different kit that has a scope attachment and bracket to hold my iPhone. Downloaded Night Eyes and Night Vision apps so the iPhone serves as both the light and camera source. The apps also offer green/red/black n white screens. Cost is under $40 via Amazon and I’ll review it later.
