DolphinEAR/PRO

 

 

 

DolphinEar/PRO hydrophones are designed using a unique large aperature MPC piezo-electric element that respond to sound pressure variations over a wide dynamic range. They are completely encased in a special epoxy casing making them far more rugged than most under-water microphone designs.

Despite it's low cost, DolphinEar/PRO provides high quality, BALANCED audio output over a wide fequency range. It is supplied with 10 meters (33 feet) of high quality Neoprene/PVC cable terminated in a standard 3 pin XLR connector.

Unlike standard ball-type hydrophones, DolphinEar/PRO's unique disc design minimizes flow noise while recording from a boat in medium to heavy sea conditions.

DolphinEar/PRO may be buried in earth, or sand, for use as a geophone-type microphone. It is also suitable for direct immersion into many hazardous chemical solutions.
