SQ26-08 Hydrophone

The Sensor Technology SQ26-08 has a very slick, compact design, and is a component in several Cetacean Research hydrophone systems, and is also sold separately.

The SQ26-08 Hydrophone is a component. It can not be used as a stand alone hydrophone.

The SQ26-08 is a general purpose hydrophone ideal for whale watching, full audio-band signal detection, and mobile underwater recording; except that it can NOT be used as a stand-alone hydrophone.

The SQ26-08 hydrophone must be used with a recording device or preamplifier that has a bias powered (a.k.a. plug-in powered) microphone input, and thus is included in the following Cetacean Research underwater recording systems:

  • SQ26-08 Hydrophone
  • SQ26-08 Hydrophone and cable
  • SQ26-08 Hydrophone frequency response
  • Cetacean Research™ Hydrophone Cage
  • Cetacean Research™ Hydrophone Cage - top view
