Guys - There was a thread about 5-6 months ago with a contact name a number for a transducer and fishfinder guru. I couldn't find it anywhere. If anyone could pass that along again I would appreciate it. I have a boat with a thru-hull transducer mounted before I bought the boat and I cannot tell what brand it is. I want to use it with a new depth finder Furuno/Lowrance but dont know if its possible. Is it just the number of pins on the cable that matters? 7-pin/10 pin???
