LS Recorders

The LS family of underwater recorders, including the single channel LS1 and LS1X-Al and stereo recorders LS2 and LS2X-Al, make it easy to setup, deploy, and handle acoustic recordings. Their compact design and the option to use of alkaline D cells means travel with these acoustic recorders is easy.

Anodized and longer aluminum housings of the LS1X-Al and LS2X-Al mean they can be deployed in deeper locations (up to 3,000m) and for longer periods than our other recorders.

The LS family of recorders share these key features:

  • Easy to Configure

    • Set record duration and sleep interval

    • Push button interface and OLED display

    • No computer required

  • Huge Data Capacity

    • MicroSD card allows you to collect up to 1 TB of data

  • Simple Output

    • Recordings stored as wav files

    • Card and batteries can be replaced in the field for rapid turnaround
