We left Prickly Bay today (Grenada) for Tyrrel Bay (Carriacou) and I noticed a consistent reading of 6m depth
on my ST 70.
Once we had rounded the southern part of Grenada
and headed North, I engaged autopilot
on a course that would be in deeper waters, whilst I went downstairs, removed the transducer and cleaned it thoroughly. I then followed all wiring
making sure all connections were nice and snug - all seemed fine.
I 're booted' the St 70's (have 2 upstairs and one downstairs) and had the same thing - 6m depth
I went to Transducer setup - search - finds 1 x wind
and 1 x DST800
(model number is DST200) s/n 1651160, software
version 1.002 and 1.005
The display (ST70 is software
Depth response level is set at 12 (all units in meters so I assume it means 12 m)
At first I thought it was due to being in water
that is too deep for the transducer echo, but as we passed over 'Kick em Jenny' I headed for Ronde Island and it became clear that even in fairly shallow water
, the ST 70 remained at 6m.
here in Tyrrel Bay - gues what depth I am in - Well ... it says 6m !
I wondered if software could play a role in this?
Does anyone have advice or experience with this problem?
