The depth portion of our ST50 Tri Data worked well last year. Now it is reading very high. It is indicating a 50 - 60 foot depth in our slip instead of 9 - 10 feet.
I looked in the manual from the PO and no help.
Any ideas?:confused:

The ST50 is such a simple system that I am surprised you're having problems. I am a little out of my depth here - sorry for the pun - but my thinking goes like this...
Have there been any changes in boat wiring since last year? How about the bottom? Has your hull become crudded up with algae? When last did you clean the bottom? (Assuming you're Michigan based barnacles won't be a problem, but other debris on the hull? Don't you folks have a quagga mussel issue up there?
In the depth display there is menu access to the depth sounder defaults that allow the user to establish the datum to which the depths are displayed. You might try 'exercising' that function just to see it changes anything. If you still have the problem I suggest calling Raymarine customer support in New Hampshire. Leave a message if you go to voice mail. In my experience they have been very prompt in returning calls.

My ST50 depth sounder exhibited the reverse issue; it read 3.5 feet in my actually 8 foot deep slip. It had been fine the prior week. As soon as I started moving out of the slip, the depth returned to it's proper value. I'm assuming something soft had fouled the transducer, but don't know for sure.

Thank you to everyone for your help.
Over the winter I painted the bezels the hold the instruments. When I took the ST 50’s out I carefully marked the wiring.
Also, I have been replacing some of the wiring in the control panel since I noticed some of the spade connectors were not tight. And some of the wires looked like they were overheated.
I went back and checked supply voltage to the instruments – 13.3 vdc.
Then I took the ST 50 tri data connectors apart and reconnected them.
Somewhere in all of that the ST 50 depth readout started working correctly.
Over the weekend, I checked it several times and things seem ok.

Good news. Sometimes electronics just need to be waked up.

So does this mean Al Gore, did not invent the Internet and the baked potato either?
