Model SQ26-H1

The portable SQ26-H1 underwater recording system consists of...

Options include

  • a bluetooth speaker system with either headphones or with a waterproof speaker which can be attached to the deck of a kayak or boat with the included suction cup mount. Sound quality is excellent!
  • SpectraPRO or SpectraLAB signal analysis software.

One of the cool things about this underwater recording system is that the hydrophone is powered by the Zoom H1's plug-in power microphone jack.

It will record sounds up to 40kHz, which is twice as high as humans with perfect hearing can detect.

The SQ26-H1 is the most compact underwater recording system that exists. Files recorded by the Zoom H1 can easily be transferred to your computer via USB for analysis with  SpectraPRO or SpectraLAB software, sold separately.
