Depth sounder dead. Was working perfectly until the morning after I got to Seaport. Since then 0.0m on the display.
A fluke it died then? after so long then to happen that night??
Did she sit on the silt and damage it? was in a close up berth at the time but not sure she touched the bottom... the trans d would be pretty hardy wouldn't it?
Did she sit on the silt and she's just caked in mud? Would have come off with a couple of trips up the river and regardless can all transducers go "through hull"?? therefore a bit of mud shouldn't worry it? Worked all the way up the river till shut down that night.
Is it just that the silt isn't giving a good bounce? then it would say max wouldn't it?
She didn't come good with 2 days of sailing. I haven't hauled her. all wiring seems intact. Nothing touched internally to stop her working.
Where to from here? New transducer? Borrow transducer and test? borrow gauge and test? Can I pull it when in the water and check it with limited ingress?

Buy another???

Tips team?

Yours Aye,

Is she covered in silt ?, wait for a warm day down there and go for a swim with a snorkel, take a scrubbing brush while you're at it.

I wish mate but NO ONE swims in the Tamar. Dry suit maybe...

Wouldn't a transducer fire through silt if they can fire through a hull or are through hulls significantly different??

If it was just silt the screen would show some noise at the surface and still show the river bottom. I had the same problem as you last year, when I had a look at the silicon attached through hull transducer it had overheated and expanded the case.
I think there is some merit in keeping the transducer in liquid. The transmission phase of the transducer produces some heat. The high end portable sounders I have used for work won't let you switch the transducer on until you have it in the water. The old sounder was a base model humminbird so it was a good chance to upgrade, the next transducer will be sitting in a container of coolant as recommended by Garmin.

The i50 is just a depth given... also an in hull. Upgrades can be bloody expensive cant they!
