Installation
On a few models of anchor windlass the sensor and the magnet are already installed (chain
counter setting). Therefore, the operations described below are not necessary.
Installing the magnet on the anchor windlass
A hole having a diameter of 6.5 mm (~1/4") and depth of 8 mm (5/16") must be drilled on a tooth of
the gipsy, in a place outside the chain's path.
In the case of vertical shaft anchor windlasses (see Fig. 1B), drill the hole in the lower circumference
of the gipsy.
In the case of horizontal shaft anchor windlasses (see Fig. 2B), drill the hole in the outer
circumference of the gipsy.
