PS-06 plastic sheave

The PS-06 plastic sheave is a small affordable magnetically encoded sheave option for use with A.G.O.’s EWC-6 wire counter unit.  It is based on a commercial Loomis Marine trolling block with magnets and sensors added for wire counting.

It is not a snatch block.  It must be almost completely disassembled to install and remove cables that cannot be fed through its throat opening.

Not recommend for use in high-line-speed applications like Sound Velocity Profiling.
