Lofrans THETIS 5003 Handheld Windlass Chain Counter Remote Control

The Lofrans THETIS 5003, part number 73632, is a wired three-button handheld windlass remote and chain counter for 12V and 24V DC systems. Its backlit LCD displays chain speed, mooring length in metres or feet and system voltage, while an approximately 4m extendable cable provides freedom of movement during anchoring.

Designed for marine anchoring control, the THETIS 5003 combines windlass operation and chain-counter information in one handheld unit. Its advanced microprocessor supports chain-length monitoring, an anchor-up alarm, voltage indication, adjustable key tones and control of compatible free-fall windlasses.

The soft rubber casing provides an anti-slip grip, while reinforced covers and buttons support regular use on deck. The handset is rated IP66 when installed, and the supplied waterproof plug and socket are rated IP67.

A high-visibility backlit LCD provides eight contrast levels for different lighting conditions. The menu can be displayed in Italian, English, French, German, Spanish or Greek.

The THETIS 5003 supports parallel connection with a compatible windlass control installation. A support bracket or cradle is included for stowing the handset when it is not in use.
