M74 Survey Transducer
The M74 is a low-frequency broadband marine transducer delivering excellent deep-water performance for survey echosounding and detailed sub-bottom profiling. It can be chirped with a long pulse over a wide-frequency band, and is available in 12 kHz and 15 kHz options.
Featuring a SEALCAST urethane housing for long operational life, the transducer includes an easy access cavity for the transformer, which can be matched to suit specific customer impedance requirements. The unit can be provided with a bulkhead or in-line connector.
