Powering down Unit powers off after a short use. Sometimes operates up to two minutes but usually less. Also seems to shut down faaster with the Ir "ON". Initially I thought that it must be the batteries. I replaced with new AA energizers. No luck. Again I replaced with Duracell. No Luck. I tested the voltage of each battery and found no less than 1.5 volts per battery. I tried Ni-Cad batteries with an initial output of 1.63 volts each. Again no luck. I am utilizing my PVS 7B in complete darkness as to avoid the bright light shut down possibility. I'm fresh out of ideas. Any suggestions? Thanks -Jay

How long have you had the system? Did you purchase from USNV or private party? If from USNV why not call them up and send it in for repair. If from private party,,,,,that's the chance you take. Sounds like you have either a failing power supply or an electrical short somewhere. In any event the system should be looked at by somebody who knows about night vision. If purchased within the past 2 years it will still be under warranty.

I have a Meade ETX-70. When turned on, the handset says there is a Motor Unit Fault: Motor failure detected due to moving handset between scopes, low battery level, obstructed or overloaded scope. I've replaced the batteries with fresh ones, with no luck. I do not understand what they mean by "moving handset between scopes". (Note: twice the motor unit engaged and the telescope rotated on base while warning was scrolling across handset,


This is usually caused by low battery power-- as the hand controller reported. DO NOT USE rechargeable batteries they do not have enough volts. Use alkaline batteries only.This can also be caused by a broken gear or a failed internal motor. You can return these to Meade for repair.Here is the contact number:http://www.meade.com/support/index.html

I recently accuired a pair of an/pvs-7b night vision goggles. When trying them out they didnt work. I checked the batteries already in them, there was no old crusty battery acid. I replaced them and still nothing. I read on how to adjust the dioptre. still nothing. Whats the deal?

Pinseeker 1500 recently stop giving readings over 100 yds. Changed batteries, no luck. Does laser light go bad and can it be replaced?


Hi, well in answer to your query, Yes & Yes. Most often though it is dirty optics? However IF you are sure that's NOT the problem. Then indeed there most likely IS a problem with the range finding Laser Diode, or the receiving detector. In any event, you will have to return the unit to Bushnell, so it can be repaired. These units require exact calibration, in a workshop, after any work has been done to recalibrate the laser and receiver, this is NOT possible with a DIY. please look below, it's common.. and seems a inexpensive task..

I dropped my Nikon LR550 Waterproof Golf Rangefinder and now it won't turn on or provide the normal display. i have tried replacing the battery but no luck. any suggestions?


Hello dh.... sadly these things, like Nikon cameras don't bounce well. Send it into Nikon for a free estimate. If you open it up you will void any warranty on it. Joe

Hello, i have a paramount/3.6x moonlight product that is not working. i tried calling moonlight products at 1-619-625-0300 without any luck. i bought it new and it appears in perfect condition. about all i can do is replace the batteries and that did not help. 1) does moonlight products still exist? 2) is there anyone that might be capable of trouble shooting the problem and telling me if it is worthwhile fixing this monocular? 3) can i trust sending this to them, expect an honest assessment, and be reasonably certain they will return it? thanks, carl


Hello, Your Paramount 3-6X was manufactured for Night Vision and Night Vision sold them to Moonlight which had their name Paramount and logo install on the monocular. Now, Moonlight uses a foil type sticker with their name and logo on the sticker and it is installed on the Night Vision Inc. Russian NV devises. Here is the bad news. The hole monocular was manufactured in Russia. I'm telling you the truth. Forget about getting it repaired. The cost to repair your monocular would be cost prohibitive. Auction it off on eBay, or you can send me a message through fixya. What do you want for it? Sorry, GB....stewbison
