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.
