For underwater recording, the DolphinEAR/Pro ($299) is a high quality, low cost solution. The omnidirectional device features a 10-meter cable (other cable lengths are optional), 600ohm balanced output that terminates with a standard 3-pin XLR style connector, and a frequency response of 15Hz-20kHz ± 3dB. The transducer is a high-output MPC (Piezo) style, fully encapsulated in a rugged epoxy case. No power is required.
