Raytheon L365 problem

[Fish Hawk]

Will show bottom and fish very well but, will not show fish arches. Unit has 240x64 pixel and 2400W, 300W RMS. Had tried moving transducer at a different angle but still no arches.
Thanks. Fish Hawk.

try turning up your sensitivity. I had the same problem at first. But the sensitivity adjustment did the trick for me. Totally satisfied now.
