Hi Tony,
A good "treasure finder" type tow fish with sonar will normally only give a representation of the surface of the deposit. You would need one with a very special frequency to penetrate the deposit layer.
If the deposit is light and the base hard rock then good results can be obtained from a scentific type towed array.
Combining the sonar with a magnetometer will greatly reduce the number of possible targets.
Your biggest difficulty would be to get the tow fish running at the best depth for coverage.
Possible, but needs practice, and from your initial question it would seem that you would need to not only import the device but the skills as well.
Regards
Ross
