configuration
The MP-25 is a high output, pressure sensitive detector for use in swamps, rivers, bans and transition zones.

The MP-25 is transformer-coupled and has 8 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. The Sidewinder version does not have the outer case.

The MP-25 Sidewinder version is designed for easy mounting to bay cable and reduction of leader cable stress. Its tapered design positions the leader flush with the cable thereby greatly reducing the friction in this area as the hydrophone travels through the squirter.

Anchor slots have been provided for tie wrapping the hydrophone to the bay cable thus facilitating the process of taping the unit to the cable.
