Hello everyone .
I'm in need of some advice on my night vision unit its a GB sights aspro . I brought it in January this year .. but its got a home made power source of two ultra fire 3600 mah batterys which only give me 20 minutes of use.... Unfortunately it never came with a manual so I dont know what power source it should have or should be using could I use a ns50 battery pack or simler ...is it 6v or 12v ...... I just dont know and have spent months looking on line for little if any information on the aspro with no luck maybe some one is the owner of one or knows what I could or s
