Reg, oooopppps, I mean Rick ;-),
I have heard/seen metal detectors that the head/coil was waterproof (except
for the controls). I think that the $$$$ was apprx. $100.00 and up.
The problem is that usually (or in our case) the search area is huge,
mostly because where the boat stopped moving is not always where it dropped.
Few years back, a friend's boat lost it's prop, at first he thought he blew
the tranny (no forward/reverse).
Upon further inspection we figured it out, so being water lovers
(in my case a frog ;-), we grabbed our scuba gear and returned to the spot.
This was supposed to be splash, 1 2 3, gotcha.......
We never found it ;-(, it's still hiding in the muck/weed/etc, and
that was after two tanks of air......
I figure that I/we have more chances of wiping out skiing and coming
out with a prop blade in our teeth then finding it diving/metal detecting
;-(........

| I have to agree with .1 It is VERY difficult to find anything
underwater if you do not have a fixed point of reference when the loss
occured and even worse if you were moving.
I have done search and recovery diving on several occasions for big
props off of small ferrys. Most spun off during docking (high rev
reversing to stop) and it is AMAZING how far those things can go.
You also get alot of side to side travel.
There are alot of brands of U/W manometers but the decent ones are not
cheap. They make some tow behind versions that work well but cost $600
up to the thousands.
One more word of warning before you do invest in a detector or throw
away money renting one... There is an awful lot of JUNK on the
bottom. Density increases drasticaly as you near a harbour or popular
beach, fishing area or other anchorage. You just wouldn't believe the
stuff folks throw overboard.
Sorry to be a pessimist,
