As Francis Fletcher will tell you

mine spent a couple of years telling me the water temperature, but not the depth.

Having a lead line, I took my time about fixing it.

Re: As Francis Fletcher will tell you

How do you use a lead line tacking up Chichester harbour at 5knts?

temperature based depth sounder

i think Mirelle actually found his way by using the water temperature, knowing that deeper water is colder that shallow, and drawing a nice graph by calibrating the temprature curves at various times of the year using the lead line. Possibly...

Actually I think Mirelle's leadline was a go faster device. Whizz it miles forward and it plops in mud, then haul oneself forward and repeat process?

IF you tie the unit onto the end of a piece of line with markings on it, drop it over the side until it stops. Then pull the line back in and see how much of it is wet, you can calculate the depth.

Thus the sounder has still done its job, ie worked, to help you find out how deep the water is.

Reminds me of the bloke starts work in a boutique and has to measure a young lady for trousers, asks his boss how to do it.

Take the measuring stick and whack it up as far as it will go. Take the wet from the dry and add an inch for turn-ups.

I had a Stowe which worked more than most. It would tell me that I had 10 metres when, by looking over the side, I could see that we had 3...

profound question, indeed. Do ducks quack, is the pope a catholic? each indicates a functional relationship one to the other eg would a pope quack or a duck be a catholic? in a purely literal sense one can have an agnostic depth sounder which works in the sense that it is in a state of working potential but has yet to reach that ineluctable and divine state whence electrons fire together to momentarily produce a desirable result eg 5.2m at puilldobrhain as if experiencing a rare orgasm ...

We say pah to depthsounders, get a fishfinder. Contours of bottom look great in colour and the trend to deep or shallow much easier to follow. Oh and it shows fish as well.

.....in a sort of way. Fish with swim bladders show up as little arcs like the top of an umbrella, bit like a crooked finger. Captain Birdseye shows up as a prat.

Now lookee here, that is a very unfair stereotype of a fisherman. It is a bit like saying that all yotties speak with a Scottish accent and sail Bendietoys.

BTW, is your Etap one of those with a lifting keel, a bit like the one that was aground for six hours in Keyhaven last Saturday?
