Hi Matt, Been at sea so sorry for the delay in
replying. The 82-88 tunable transducer was from
It seem to lack power and did not seem to be able
to separate feed just above the bottom, feeding fish
and reading bottom softness/harness was not as good.
I guess I got spoilt with 38 Khz@ 3 Kw.I prefer
38 Khz as the sound cone on the bottom is smaller
than that of 28 Khz. This limits the interference
caused by reflected echos and ghost readings on
uneven and very steep bottom. We can still get
feed and fish on near vertical and fast dropping
walls and have learnt which are real soundings
and which are ghost images. I hope this helps.
