I need to find a sonar transducer that transmits in a full 360 DEG=20
pattern.  All fish locators/ depth finders transmit in a 60 DEG cone.

I also need some one who can design a circuit that would send out a ping=20
for a short time ( less then 100MS)  Also the circuit would listen for a=20
ping and thenout put a signal.

I have communicated with design techs work with fish locator and sonar=20
units.  They tell me they cant help but claim it would be a peice of=20
cake for an electronics technician to design a circuit.

Is there any one out there who has the ability to do this and would want=20
to help with this?
