The Sync Humminbird Logging System (SHLS) is a compact, easy to use, shallow water mapping system. The SHLS is a portable, PC based, logging system that collects and records time-stamped, georeferenced, multibeam data. The system uses a customized Humminbird Wide 3D Paramount fishfinder.

The Humminbird sonar uses 6 separate beams for mapping the bottom. The 6 beams provide 53 degrees of continuous coverage up to 70 metres deep. The acrosstrack coverage is approximately 1 times water depth. For example, in 10 metres of water, the swath width is 10 metres with a resolution of 1.6 metres.

SHLS Application

The SHLS operates in water depths ranging from 2 to 70 metres and works with most shallow water vessels. Possible applications for the SHLS include:
