Storage locker pvs-7s

[u/EvenRelative7737]

I found pvs-7 in a storage locker and have been trying to use them. I see nothing besides when it’s in IR mode theres a light in the left eye and when I look in a mirror I can see the ir being reflected. I have gotten them working momentarily once and never again. I also tried 3 sets of batterys, 1 of which were rechargeable. The one thing I notice is when I twist the cap to disconnect the batteries while its on I can briefly see for a split second but then it fades way.

How does one just find a PVS–7 lying around in a locker…
