Hi Gabriel,

Have you managed to find a transducer yet ? If not, let me know, and I =
can send you one. All you owe me is for postage (the cavity and cooling =
fins etc. weigh a few ounces.....).

I used to work with these a few years ago, and we had a lot of problems =
with the transducers drying out. A circuit to sennse the presence of =
water is necessary. If no water , the transducer would swing to much and =
crak.

P.S. You need a fair bit of power.D.S.
