Underwater Recording Systems include a hydrophone and a digital recorder. Autonomous, Computer-based, and Portable recording systems are available. The portable SQ26-MT is the most compact underwater recording system that exists.

Portable recording

Model SQ26-MT

The SQ26-MT underwater recording system consists of the Sensor Technology SQ26-08 hydrophone and the new M-Audio MicroTrack II solid state digital recorder, a 4GB high-speed compact flash memory card, solar chargeable battery pack to provide more than 10 hours of continuous recording time, a 12V USB power adapter to charge the MicroTrack's battery while in the field, and a waterproof Pelican case with custom anti-static foam to protect the system. One of the cool things about this underwater recording system is that the hydrophone is powered by the MicroTrack'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-MT is the most compact underwater recording system that exists. Files recorded by the MicroTrack can be transferred to your computer directly or via USB for analysis with SpectraPRO or SpectraLAB software, sold separately.

Model C55-E44

This underwater recording system consists of the Cetacean Research™  C55 hydrophone and the  Edirol R-44 digital recorder. This professional, portable, 4-channel system features sample rates up to 96Hz at 24-bit resolution. Files are recorded directly to a SDHC / SD memory card on the R-44, allowing for virtually unlimited CD-quality recording time, depending on the size and quantity of the SDHC / SD memory cards on hand. The files can be analyzed with SpectraPRO or SpectraLAB software, sold separately.

Model C55-F2

This underwater recording system consists of the Cetacean Research™  C55 hydrophone and the Fostex FR-2 digital recorder. This professional, and very portable, system features a sample rate of 192kHz at 24-bit resolution! Files are recorded directly to Compact Flash memory or to PCMCIA Flash Drive on the FR-2. The files can be transferred to your computer directly or via USB for analysis with SpectraLAB software, sold separately.

Computer based recording

Model SS03-T144

This underwater recording system consists of the SS03-10 Sea-Phone hydrophone and the  TASCAM US-144mkII USB audio/MIDI computer interface. When connected to your notebook computer, the SS03--T144 becomes a portable digital recording studio with 24-bit resolution and 96kHz sample rate. The sounds can be recorded and analyzed with SpectraPRO or SpectraLAB software, sold separately.

Model C55-T144

This underwater recording system consists of the Cetacean Research™  C55 hydrophone and the  TASCAM US-144mkII USB audio/MIDI computer interface. When connected to your notebook computer, the C55-T144 becomes a portable digital recording studio with 24-bit resolution and 96kHz sample rate. This system has a better low frequency response than the SS03-T144 and is expandable to higher frequency sound acquisition for future applications. The sounds can be recorded and analyzed with SpectraPRO or SpectraLAB software, sold separately.
