You are having a problem with parallax. This is a common problem with Gen 1 equipment. Be sure to use a FRESH and high quality battery. Do not expect a picture perfect image with GEN 1 equipment. Be sure to follow the instructions that come with the unit.

OK, is the IR luminator working with a red glow. Don't look at it. Some these IR luminator have a adjustable lens that one can screw out or screw it in. If the IR isn't igniting then the LED could be bad , broken wire, or bad switch. stewbison

double vision ( ghosting) sometimes indicates an antenna misalignment/ bad connections or reflection of the signal from something like a roof or building wall

Unit simply does nothing when its turned on. the IR assist still works. (AN/PVS-7B/D


Letto, This PVS-7B has a generation II image intensifier tube in it. The image tube is manufactured by ITT liton company. The only way to fix this wonderful NV devise is to send to ITT Night Vision Company. They are listed in the internet. Unless you can find someone to work on it, but the really need to know what they are doing. stewbison

My pvs7 wont stay on thay shut of after 30 seconds and then start to shut of ever few seconds


Hello, have you or someone else pointed this night vision devise at bright lights, street lights, head lights. If so, maybe the damage has/hasn't alread been done. STOP. This PVS-7 goggles with ITT image tube with generation 2 or 2+ or possibly generation 3 tube. The devise is an American made unit, and the best in the world. Nobody can compete with the USA on NV. They sat the standards on Night Vision.

Have you replace the 6 volt battery? Get the goggle in a darken room then turn the switch on.
see if the 25mm plate will turn green and stay on. But first replace that battery.
Therefore, if this test works, then never and I mean never shine NV devises into bright lights, it will destroy them every time.

PS. send me another message and let see what happen. stewbison

Looking to buy a used pair of pvs 7 nightvision goggles and owner says there are a couple of small black spots when you view is this a cause for concern and what else should i look for ?


Hello, that is normally to have some black spots. Now, if tries to tell that this Military spec. He wrong. Two black spot on any image tubes used by the US Military is rejected, they only allow one black spot and that if everything else is OK. How fuzzy is around the outer circle of the image tube. If there is a uniformed green pattern through out the scope. I would say it was OK. But remember "Buy be Aware". GB...stewbison

Double vision..


Adjust the convergence in the menu. If it will not adjust then solder connections on convergence ics or ics themselves need replaced.
