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 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-H1 compact portable hydrophone system
- µRUDAR-mk2™ autonomous underwater recording system
- SQ26-08 Hydrophone
