[CA] [CA11] ST60+ Depth Reading Issues

[adam.zyborski@gmail.com]

Hi,

I have noticed on occasion erroneous depth readings, for example sailing along at ~60m depth and suddenly the depth appears to drop to less than 5m which could not be justified by chart readings.

I am currently moored at a depth of ~6m, and every few minutes the depth reading takes a dive down to less than 2m - see attached short video of the depth reading as seen on my graphic display.

I turned off all instruments for a minute or so, turned back on, but the problem persisted. I then turned all off for an hour or so, turned back on, and the problem seems to have gone away (reading steady 6m).

What is the most likely cause ? Transducer or ST60+ display ?
