It's a 640. It punches way above its price point. FWIW, I've owned both an Nvision NOX 35 and an Nvision Halo XRF, the latter which many consider to have a better view than than the Trijicon with the 60mm lens. The Pard SA-62 also has the ballistic calculator with the holdover for the distance you want to shoot to. One of the most difficult aspects of shooting at night is judging distance, and is even more difficult when using an air gun.
@karl_h I don’t know about all of those details, but I’ll look into it. Thanks for sharing. I know what I’ve experienced with thermal and night vision regarding humidity (separate issues). For my needs I believe that I can trust what ETX Hans and Jason on the Late Night Vision Show discuss, record, and post. We’re in the same region.
@cmatera I recalled tht you had the N-Vision Halo. I have a buddy with one and he’s shared good things about it with me. From recordings I’ve seen, the IQ doesn’t look too superior to some other 640 units out there (Pulsar and Infiray), but I’m told in person the images look good in the Halo scopes.
Like many, I use a handheld thermal monocular for detection and the scope only to shoot when they are close. The scanner quality is far more important than the scope. The scanner is used for hours, the scope for minutes. Guys who need to save $$ will buy a 640 scanner and a 384 thermal scope. If money is really tight, some use a handheld thermal scanner and regular night vision or even digital night vision. My scanner is a Pulsar Helion XP 50 Pro. When I use my PB's the LRF is not as important. They shoot much flatter in trajectory than air rifles.
I looked at both, I really liked the bolt better. I don’t know if it was the screen or what but I felt it was better. We had(all640) 2agm,2 Bering optics,2 Rico, and 2 pulsar set out. Then he brought out the bolt as me and the wife were handing them back and forth setting them in order. She pretty much said buy the bolt, it was by far my favorite in my price range. I got a quick glimps through a halo, but still liked the bolt. I think pulsar makes the best scanners, but this is just all my opinions. Everyone’s eyes are different and technology is alway evolving. Fusion and thermtec are two other brands to look at. It’s hard to beat comparing scopes back to back. I wish my bolt had the red monochromatic like pulsar, it’s easier on your nightvision. I really like the button layout on the bolt.

www.opticsplanet.com The Burris hasn't seemed to grab any real traction. When they first came out I was enquiring about them on other platforms and caught a lot of snears and jeers without substance relating to their merits (or lack of).
