I put this up on find mall also and thought it should be here too.
I just finished my water proof compadre mod. The compadre is the first detector that I bought and I still like it the best. I got a new 7" compadre and decided to mod my old 5.75" verison in to a water machine. It has volume, and sens, and disc on the inside (waterproof pots are $50 each so I didnt use them). It works so far (tested in pool) I will be happy to share any info I used to help others buld on mod similar designs.
Parts
Compadre, small water proof box ( from Dicks), Small on off switch, 10k ohm pot and 100 ohm resistor(sens), 5k ohm pot( volume) some knobs for the new pots, 9v battery holder, water tight cable clamps, rubber switch nipple. I found a pair of minelab excal headphones on ebay. I could only get one side to work so I took out the old buzzers and used some 300 ohm speakers I had. Then re sealed them in. Used some 1/4-20 nylon bolts and electrical conduit to hold control box to shaft. I used pvc and a heat gun to make the internal mount for the parts.
I changed out the normal Compadre disc pot (100k ohm with switch) to a normal 100k ohm pot. I didnt have water proof pots so I figured the next best thing would be to set up the detector how I like to run it, and then just turn it on and off from the outside. This would reduce the amount of opening and closing the box when potentially wet or dirty. I generally run my Compadre set about Iron and leave it there, so this works for me.

Lots of great info. THANKS! Hoping to do a water mod myself, but have stalled out, have got a straight shaft made up & water proof box. Wanted to do a back pac or chest type mount, but like you said coil wires to short. You do not have to CUT the ends off the wires, in order to use the m3207's do you?
