[CA] Erratic sonar readings
Advice/help required..
Fitted a new Raymarine E97 MFD a few weeks ago along with a new transducer (P48) - today was our first trip out to sea, MFD was great but the sonar readings were awful. Plodding out of the marina they looked fine and the readings were as we would expect but once at sea - dreadful! I know they are not great at speed, that doesn’t worry me, but the sea was lovely and flat, drifting at 1 or 2 knots, readings were jumping from 3ft to 60ft to 170ft - just all over the place! We were in about 200ft of water. Transducer is in the same place as the last one we had fitted (Dragonfly 7 Pro) and that was great. Setup on the MFD seemed ok, it recognised the transducer and set the correct frequency. Any thoughts? Cheers.
