Failing depth sounder ouput

[AngeloM]

Hi Chuck,

I did verify the E120 was specifying the correct device (B744V). Also attached are a couple of photos taken of the transducer that you requested. if this not what you requested, let me know.

Just to share my more recent experiences. Just outside of our marina, past the Navy pier, the bottom goes from 30 to 40 feet to below 200 feet in a matter of a 200 yards or so. The depth sounder reads leaving the marina and stay well behaved until 60'. Below 60', the reading stop (both the sounder image display and the digital readouts). I tested this by exiting and returning to the marina several times and at different speeds (4 knots to 12knots, its a trawler.) Coming back in, at about 60' in would acquire the signal and both the display and digital readout would provide depth readings. I the tests it was surprisingly consistent at loosing and reacquiring the signal at +/- 60'. I've been trying to figure out if there is some setting that I'm missing that has a value of 60'.

What would you suggest as next steps.

Cheers,
Angelo
