That looked extremely promising until I saw the price. $55,000!!!!!

I think I will wait until Walmart stocks them.

I know this this might seem daft, but, I was idly wondering whilst gazing
at my carnation shaped propeller if a second, narrow angle depth gague with
it's transducer shooting horizontally forwards just below the water surface,
would give advance warning of an impending prop repair? (alarm set at, say,
40 feet). How would the sonar cope with seeing (hearing) the water surface
and waves? would 2 sonars interfere with each other?

Echopilots are a bit more reasonably priced. But they are best suited to
sailing boats - if you have a carnation prop I take it you are going quite
fast...

Not fast at all, less than 5 mph. I was about 20' west of the moorings round
the back of the island north of Belle Isle on Windemere. (in-case you happen
to find yourself there ;-) The boat came to a dead stop. I think the skeg or
the leg jammed against a rock as the prop, still turning, tried to drill its
way through the side of it. It's amazing how much damage can be done in just
a second. I also caught my spare prop, leaving the middle of the Brock Hole
(?) jetty south side. 2 props in one day, I hear the cheers from speed limit
supporters!
This was Easter this year, about a week before the TV report about how low
the water is on Windemere this year...

Quite often actually - but normally on a windsurfer so not much worry!

That collision avoidance scanner looks interesting. Wonder what it will
cost and if they will make a smaller unit like their FLS Bronze unit. I
am not so concerned about the forward bottom profile. I want a device
that will detect anything between the surface and say 10' deep out to a
distance that will give time for reaction. The Interphase Probe would
probably work but the Echopilot looks to be a lot more sophisticated and
easier to interpret.

Yes, it looks great and just the ticket, but £44000 will buy a lot of new
props. I was thinking of adapting an old fish finder I have. The image shows
the sender at the bow of the boat, which is fine for displacement craft. It
would have to be mounted at the stern for planing hulls, and it would see
the boat hull. Would the setup be reliable with the 'bounce' and the ever
changing angle of attack to the water. What about rough seas?
