Hi all,
I purchased a boat 2 years ago with a raymarine e80 screen, DSM 300 sounder module and thru hull airmar b164 transducer. Fantastic soundings at all speeds and at depths up to 80m. I've been going further out lately and started to notice that I lose all info after I go deeper than 80m, drifting or going over slow. Heard about issues with the dsm 300 module so I got a new CP370 from raymarine. No difference. It's 1kw setup so it should do 500m easily. I've increased ping speed, changed from 200 to 50hz, left it in auto settings, turned it off, reset settings, increased gains. Have I missed anything. The depth display just flashes and shows nothing until I go shallow again.
Any ideas???
