Bathyswath is a comprehensive bathymetric & seabed mapping survey system, derived from the established & respected SWATHplus system, now renamed as Bathyswath 1. Bathyswath 2 is the latest generation of the Bathyswath 1.

Bathyswath uses wide swath widths, this increases survey speeds significantly, especially in shallow water.

It has 3 frequencies: 1 1 7, 234 or 468 kHz to be used respectively up to 350, 200 & 80m of water depth.

The US Geological Survey (USGS) said: “Operating swath of the bathymetric system ranged from 15 to 20 times water depth in in depths less than 15m”.
