The CSW-10 is the bigger version of the CSW-7, our most popular and versatile design. The CSW-10 is useful for medium cable lengths combined with large cable bending diameters or heavy weights in almost any light-duty marine application. It's a four person portable model that is capable of lifting and lowering most instrumentation payloads (595 lb/270kg typical, please contact us for more information on load pull and line speed, values can vary significantly). This winch comes as a complete package, including a range of standard features only available as options on our other winches.

The CSW-10 is directly available from several instrument manufacturers, equipped for use with their sensors. These manufacturers include: L-3 Klein (Klein 3900 and 5000 Side Scan Sonars), Marine Magnetics (Seaspy magnetometer) and CMAX Sonar (Side Scan Sonar).


It is used to perform CTD profiling, side scan sonar, magnetometer towing, Rosette water sampling, towed instrument sleds, environmental and pipe line monitoring, lightweight grab samplers and small capture nets.
