DSG-ST is the lowest-power underwater acoustic recorder on the market giving unprecedented deployment times. Recordings are saved to high capacity memory cards. DSG-ST was designed to be easy to assemble and deploy, so you can get started with making high quality acoustic recordings over long time periods. We also offer a mounting kit to simplify bottom or subsurface line mounts.
Easy to assemble and deploy with an LED in the hydrophone to indicate when it is recording.
Everything is included to get you started, including a memory card and hydrophone.
PVC (depths to 300 m)
Aluminum (depths to 3,000 m).
Higher sample rates allow you to record higher frequency sounds. The highest frequency that can be recorded is one-half of the sample rate. Higher sample rates use more flash memory than lower sample rates.
Sample rates up to 288 kHz, including 24, 36, 48, 72, 96, and 144 kHz.
Up to 100 days continuous recording and even longer with intermittent recording on a duty cycle.
