NASA depth sounder

The alarm is missing from mine. There are several 12v piezo alarms on Ebay - does anyone have a specification for one that will fit please?

I used one of these:

but I don't think it really matters.

That's brilliant - thanks very much for the quick reply. I will be in Maplins tomorrow!

I find the alarm supplied bloody annoying. In the end I cut the green wire. It didn't explode!

Ideally it would be replaced by something that makes an occasional sort of throat-clearing 'harrumph' sound when the depth drops below the pre-set 'trigger' depth; then becomes a persistent, faux-nonchalant, not-quite-a-tune whistling as it comes uncomfortably close to the keel depth; then plays 'Air on a G String' (Hamlet ad theme music) once firmly aground!

I used to crew on a racing Stella, and when short tacking against the tide, wifey would call out the depths. On one occasion I was given that job and we ran aground first tack.
The skippers explanation, " Oh I don't listen to what Margaret actually says, just her voice pitch. I don't tack until she is squeaking. You didn't squeak"
