The slim line MP-26 is designed for the modern techniques that are being used for inserting hydrophones into the ground water in transition zones. Both the unit itself and its optional outer care are pointed at the end to facilitate efficient insertion and retrieval. The slim line outer case includes an attachment area for a stainless steel harness used for retrieval purposes which greatly increases the percentage of hydrophone retrieval.
The MP-26 is transformer coupled and has 4 piezo-electric 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, slim line polyurethane case. Standard natural frequency is 10 Hz. Operational depth is 1 to 250 feet.
