Bathyswath-2-UW 234kHz

Product Name:Bathyswath-2-UW 234kHz
Description:Bathyswath is a comprehensive bathymetric & seabed mapping survey system, derived from the established & respected SWATHplus system. Bathyswath 2 is the latest generation of our bathymetric systems. The Underwater (UW) version of Bathyswath has the system electronics inside a pressure-tight sub-sea unit bottle. This is useful for mounting on the end of a pole fixed to a survey vessel, or on sub-sea vehicles. You will not find lower prices for a similar quality (IHO standards compliant, bathymetry and sidescan). Bathyswath provides wide swath widths; this increases survey speeds significantly, especially in shallow water. It has 3 frequencies: 117, 234 or 468 kHz, to be used respectively up to 350, 200 & 80m of water depth.
