I found a monocular on sale locally. They are asking $1500 which seems like a good deal, but as a newbie I'm not sure what questions to ask.
Armasight MNVD 51-3a
From the photos they have provided, the housing is in good shape, I don't see any major blemishes in the image. Name plate indicates 2019 manufacture and the owner says only a handful of hours of use on it.
Comes with the Armasight bag and manual, no mounts or anything else.
Original Specifications attached, this is a discontinued product
I believe this is a Gen 3 tube not sure how to tell as the specifications say 2+ or 3, so if I can get a good deal, it could be swapped into a different housing at a later time?
What else should I be asking? What should I look for before I spend money on this thing?
Thanks in advance.
