    Tried setting up one of these for my non-dominant eye in conjuction with a PVS-14 on a TNVC bridge a while back in the hopes that I could transition between thermal/nvg by simply switching between one or the other (either flipping them or just closing one eye or the other).

    Didn’t work. This is definitely a handheld monocular despite having a mounting interface. YMMV.

      Can you expound on this? Was it the eye relief, lag/refresh rate, or something else? Thanks.

    • Fact check says:

      That’s interesting considering this new product was just released 2 days ago. So I’m a bit confused on how managed to get this product well before it was even made public. When did you try to set this up again?

      • Joey says:

        I think someone wants to seem like they have something important to say and/or wants people to think that said person has the money for both NODS and thermals. Wants to look like a grand thumb or t. Rex arms or a BRCC YouTube video.

    I hope that one day thermal monoculars will become more affordable I’ve used a few in the $800 range that were incredible I can’t imagine what a $3,000 thermal would look like and I can’t wait to win the lottery hopefully soon so that I might have a chance to check these things out
