Hi
I have a question regarding the deep water performance of my M265LH transducer. I have a TZT14 with a DFF1-UHD mainly for deep water fishing, but are not to impressed of the performance. I had the same equipment with me on a 3,5 year sailing/ fishing trip from Greece to Australia, then installed in a 41" catamaran. The same in hull transducer worked perfect through 15mm (0,6 inch) solid fiberglas, reading bottom down to 1150m (3400`)! After returning to Norway I have the same electronic put in my Contender like 26" CC, and now I have trouble reading bottom in more then 400m. Only difference is the hull is now 30mm (1,2 inch) solid glas. Earlier I had a Airmar 258 mounted in hull in the exact same spot, and had as good or better readings on an old Lowrance. I have been told that the chirp is not as good as the traditional in really deep water, but find it strange that the set up did great with half the glas on my catamaran. 1100m in my catamaran was on hard bottom, the 400m+ is softer bottom, but the 258 did better. Only difference is my CC is more unstable than the catamaran, so might be harder to pick up returns, but again the 258 did at least as good. There is also a setting in the sounder "start setup" I have not noticed before and find a bit strange. There is an adjustment of gain with "off" "minimum" or "auto". Should there been a medium or high? Any idea?
