The Sensor Technology SQ26-08 hydrophone is a general purpose hydrophone ideal for whale watching, full audio-band signal detection, and mobile underwater recording. This hydrophone has a very slick, compact design. The SQ26-08 must be used with a recording device or preamplifier that has a bias powered (a.k.a. plug-in powered) microphone input, such as the MicroTrack II used in our SQ26-MT system. If you are looking for a general purpose hydrophone for listening to underwater sounds without recording, then please see our SS03-10 Sea-Phone hydrophone.
