Thanks for the info.I had read or talked to someone about this before but i forgot the information.I dont think my fishmark 320 has that kind of power.lol.The way i fish most of the time i only use mine for depth.This spring i have a couple ambitions.1.To try and master my electronics or upgrade and learn them.2.Learn how to fish offshore structure.3.And maybe put down my finesse gear and go strictly for monster fish,,,unless im fishing for a fish fry that is.Thanks again...John.
