Looking for ultrasound transducer

[cronxeh]

I cant seem to find a simple ultrasound transducer probe (that wont have "medical" tagged on it, hiking up the price). I need at least 1.2-2.5 mhz, 360 deg cone, high power. Dual element PZT. This is for marine application (side scan sonar/ROV imaging). Can anyone tell me where I can find it, preferrably cheap?

The Physics Today Buyer's Guide (http://www.physicstoday.org/ptbg/search.jsp) lists a few companies in the ultrasonic transducer (http://www.physicstoday.org/ptbg/resultsP.jsp?state=0&&cat=2037) category. Maybe some of them will have what you need.
