Looking for ultrasound transducer

[cronxeh]

I can't seem to find a simple ultrasound transducer probe (that won't 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, preferably cheap?
