The winder includes a mechanically driven depth counter to show the operator the depth of the sampler at all times. The design also includes a reduction gear drive between the winding handle and the reel to assist the lifting and lowering of samplers.

The stainless steel cable avoids contamination that can occur with ropes and chains, and the special hook minimises the risk of a sampler becoming detached from the winder.

The hook and cable, together with the winder’s earthing strap, ensure electrical continuity and prevent the build up of static electricity.
