CruzPro: CH30 Chain counter

CH30 Contacatena CruzPro

Intelligent chain counter for CruzPro CH30 winch, self-loosening function, ideal to set sail and leave the anchor at the desired length.


Unlike the CH55, the CruzPro CH30 is a real computer available to the winch. Displays the meters of ground chain and battery voltage at the winch. It can be programmed to automatically slow down the ascent of the anchor when only 1.5 Mt of chain remains, thus avoiding abrupt blows to the delphinarium.

The self-loosening function allows you to reduce the speed of pull in proportion to the length of the remaining chain. It can automatically release the chain and stop at the desired length. If the chain goes out of place, the CH-30 immediately locks the winch. Each time the anchor is sailed it can be programmed to go back a few meshes to relieve the tension at the winch. NMEA 0183 output or external alarm output. Power supply 12/24 Vdc.
