The versatile, portable SQ26-H1 is the most compact underwater recording system that exists.

The SQ26-H1-SP system includes everything listed above, as well as SpectraPLUS-SC signal analysis software. This entry-level system is our most affordable underwater sound monitoring and analysis tool.

The portable SQ26-H1 and SQ26-H1-SP underwater recording systems include...

Options include...

  • a Bluetooth transmitter for the standard waterproof Bluetooth speaker
  • a larger 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!
  • SpectraPLUS signal analysis software (included with the -SP system).
  • a hydrophone cage for protection, flow noise reduction

One of the cool things about this underwater recording system is that the hydrophone is powered by the Zoom H1n's plug-in power microphone jack.
