The M36 hydrophone was developed as an aid in the area of marine observation. The M36 is available in various configurations, including two depth ratings, current or voltage pre-amp signalling, and 0-35dB gain, all selectable at time of order.
The M36 comes standard with a male 8-pin micro bulkhead connector from Subconn.

The M36-100 is a wide-band omni-directional hydrophone designed for marine observation. It comes with a pre-amplified output of 0 to 35 dB (selectable on order) with current or voltage signalling (also selectable at time of order) and is capable of deployments up to 2500 metres.
The M36 is also available as the M36-600, a deep-water version of the M36-100 capable of deployment in water depths up to 6000 metres.
