I just bought an old Whites 5000D GEB TR Disc Series 1 metal detector from someone. He has a single 9 volt battery hooked up to it. My question is...How many volts does this unit require? I think it is 12 volts but the battery pack is missing and I am not sure. I do know that some of these run off of a battery pack plus a nine volt but I think this is just the 12 volt system. Can anyone verify this for me? Could I go to Radio Shack and get a 8 AA battery holder and would this work? Also inside the battery door there is a date stamped "OP" What does this mean? Sorry about all the questions but I am new to this model so any input would be appreciated. Thanks, RDF
