how cool, i had a lowrance x-15 paper graph, it would draw great pictures, paper was costly[:@], and it would break stylus/belts pretty regular (also costly)[:@]. wish i could help with power and transducer info, but i'd bet it would be easier to find old ray jefferson stuff, and that ain easy[:-][&o]

good luck

try sending these guys an email, seeing how they are a florida company that may be why it "showed-up" there[&:]
