Marport’s NHT Hydrophones are the crucial conduits that detect the signals from gear-mounted sensors. For full coverage under all conditions, we recommend that port and starboard hydrophones are used to ensure uninterrupted reception. We offer both towed paravane hydrophone and hull-mounted versions for trawl and seine use.

Our hydrophones are designed with dimensions to make them direct replacements for standard industry units, and we offer a comprehensive range of hydrophone types and configurations with passive and active options to meet virtually any requirement the fishing industry can throw at us.
