Depth gauge - transducer?

[ITH]

I have inherited Siemens VDO instruments on my newly acquired motor sailer - including depth gauges in cockpit and inside helm. Cockpit gauge is kaput and needs replacing, but I'm told that Siemens VDO are no longer available. Can I fit someone else's gauge (Raytheon?) using the existing VDO transducer - or does the complete package have to be installed?

Have a look on Airmar as in airmar.com. They do transducers for everything, you will be able to cross refer what you've got and what you can use with it.

Thanks for that; I'll rummage round the web site.

Funnily enough I just gave the link to another post. See the recent one on Cetrek.

If I read you correctly you have a depth sounder which works OK on one readout but the other is kaput. This might indicate that you have just a repeater indicator failed. Or does it indicate you have 2 separate systems?
Come back and tell us which it appears to be. A repater may use a NMEA code in which many different indicators will work or it may be just a DC connection. Is there a separate power supply to the kaput indicator? How many wires go into it and of what type?
Let us know olewill

Will do - as soon as I'm back on board. Boat is currently in Holland, me in UK.

Why waste a lot of time if it is old anyhow.
I had same problem on my motorsailor and messed about for weeks, finaly bought a new Nasa Target 2 sounder, fitted it in 4 hours and works perfectly with big digital backlite readout.
Found a good spot in the bilges clear of the engine and keel and just glued the transducer down after testing first with 'Blue Tack'.
