Hi all,
I'm new to the group so first time post.
Question I have is that I have a GP 1870 Sounder/plotter running a P66 transom mount transducer and when I use the unit in full manual mode in 200Hz , I cannot adjust the gain to max(100%) without it showing anymore noise/clutter. The boat is stationary and the picture of the screen from the top of waterline to the bottom is very clear. It will show schools of fish, but I cannot adjust the gain to possibly see more fish.
If I change to 50Hz and I adjust the gain to max, the screen becomes noisy/cluttered which I can tune out with less gain or by adjusting the clutter etc.
Has anyone else encountered this at 200Hz setting?
Appreciate your replies.
