I recently replaced an old 292 with the FCV295 and am having trouble with the low frequency performance. It will not read the bottom, display a depth reading and the display I do get looks suspicious and runs slowly in deep water on both HF and LF. After much checking, I suspect my transducer is the problem. I have a CA50/200-12M. I mostly do offshore trolling but occassionally bottom fish with the boat. My question is what power (Kw?) transducer should I consider? Any recommended models would be appreciated.
