When on the sea trial, the Raymarine Tridata depth gauge wasn't giving a reading and was stuck on "Calibrating". An idea what could be casing this?

Don't know why it's doing that. Probably something simple like the software has crashed. Power everything down and turn it all on again. I.e. disconnect the batteries. If it's easier pull the seatalk plug out the back, count to 10 and plug it in again

A need to calibrate!
They have a dealer calibration mode but I would have thought it would reset when it was turned off.
It is cryptic - hold 2 buttons for 5 seconds type thing so just check the manual.
Surprised that was not grounds for rejection!

IIRC, On Andiamo you've got the same st60 tridata as in my DP.
And I'm 90% sure that it only gets inputs through the seatalk connector.
What I mean is that I'd expect the fault (if any) to be elsewhere, with the tridata just saying what he "sees".
If you access the sounder page on your screen, don't you seee some settings option or similar?
That's where I'd look first, but I can't be more accurate 'cause I'm at the airport atm, with no access to my dashboard and its manuals...

That's tongue in cheek J, 'innit?
It's such a small issue, thar you're likely to find worse problems even in brand new boats...!

No, Pete is a hard man. Several experienced yacht brokers have given up the business and gone into therapy after having dealt with Pete

Indeed and we'd already chipped off a few £k during the sea trial. If I'd suggested a further discount for the depth gauge not working I think the broker would have thrown me off the boat!

Pete. If it is broken I have a spare. I have bought a new one but only need the locking ring part. Am in the process of trying to sort different part

Thanks, I'm hoping that it's just got stuck in some calibration mode and disconnecting it will fix it.
Failing that, then I suppose it could be the transducer. Is the part you bought a AIRMAR P79? Do you know if it can be replaced whilst in the water?

Yes and Yes. Twists and comes out of oily medium. Careful unscewing else you'll snap a plastic arm which is what someone did to mine

Another numpty question....
My boat has a newish plotter (Seatalk NG) and an old plotter (Seatalk) plus all of the usual Tridata stuff. I see from the boat's manuals that there's a Seatalk NG <-> Seatalk Converter, which would make sense. I note from the Seatalk Converter manual that the A/P has to plug directly into the plotter (I assume the old one) so no big deal on that front.
However, from what I can recall the Garmin VHF uses NMEA0180 which is semi compatible with Seatalk. However the VHF doesn't appear to be picking up a GPS signal. So what would be the recommended way to connect the VHF with my other kit?

Thanks might take you up on that offer!
Spent a little time investigating this today. The tri-data is actually showing three dashes for depth and the plotter isn't displaying a depth either.
The sounder in the hull looks intact but I haven't opened up the dash yet to see whether it's connected at that end.
Does anyone know if the sounder can be swapped whilst the boat is in the water?

the P79 is fixed in the hull and not though the hull. When you take it out ( unscrew and lift) make sure that the oily medium( propylene glycol antifreeze is recommended) which sits in the bottom of the housing stuck to your hull, needs to be covering the downward face of the sender.

Thanks Mike, is it possible that there's insufficient antifreeze in there and if I pour some more in it might start to work?

Hi Pete
yes it could, it needs to have no air pockets whatsoever between the sender head and the seawater beneath the boat so the liquid used need to be the correct amount (71 ml) to cover the head facing downwards. Sometimes air bubbles in the actual GRP can distort/prevent the reading.The original liquid might have leaked out or not have been filled properly and also check the orientation of the head mine is a 20 degree angled hull and the marks on the unit reading 20degree need to line up otherwise it could be looking at a totally wrong angle. I doubt its the latter if the previous owner fitted it properly.http://www.airmartechnology.com/uploads/InstallGuide/17-217-01.pdf

I'll check the angle (I assume it was factory fitted) but suspect that even if it was mounted at the wrong angle it would find something solid to get a reading from, even if totally inaccurate. When I'm there next I'll check the connection to the tri-data, the angle and the glycol level. 71ml is pretty precise though so I'll have to get a syringe! Note that the excess cable for the depth sounder and the log have been looped and cable tied in place and one of them has a load of insulating tape on it so it could be a bad connection there.
As the sender has no moving parts, do they ever fail?
