Hydrophone

Pressure Sensitive Detector
 
The MP-24 (shown at left) also comes in a yellow pointed Split Case which eases planting in marshes, etc.
Easy method to check polarity
Full one year warranty
High output
Acceleration noise canceling configuration
The MP-24 is a high output, pressure sensitive detector for use in swamps, rivers, bays and transition zones. Sensitivity is approximately six times that of the GS-20DX geophone.

The MP-24 is transformer-coupled and has four piezoelectric crystals connected in an acceleration-canceling arrangement with each crystal operating in the high sensitivity bender mode. The crystals and transformer are permanently molded in a durable polyurethane case. This sealed unit has a thermoplastic resin outer case with easy access ports for polarity testing.
