This is a winch system for vessel-based calibration of echosounders, sonars, etc, using a calibration sphere. It comprises three battery powered winch\/pole units, two winch controllers, and transit cases for these. An Android app is available to show winch status. It is supplied as a kitset that requires some assembly and the provision of some components youself.<\/p>\n\n\n\n

The winch controller provides a raise\/lower switch for each winch, a speed dial that applies to all winches, an on\/off switch. Two controllers are provided for redundancy.<\/p>\n<\/div>\n\n\n\n

Each winch unit includes a telescopic pole, the electric winch, and the battery mount. All of these are fixed to a plate that is easily secured to the vessel railing. There is a security rope on the inboard end of the pole that can be attached to the vessel. <\/p>\n\n\n\n

Each winch can lift a 3 kg load at maximum speed (1 m\/s) and 6 kg at slower speeds. The winch reel can hold at least 150 m of 0.5 mm diameter line. The rechargeable lithium-ion battery provides sufficient power for about five hours of typical operation.<\/p>\n<\/div>\n\n\n\n

An Android app<\/a> is provided that shows line out, speed, direction, and battery state for each winch. The line out values can be zeroed and saved to remember the line lengths for a particular sphere position. The app communicates with the winch controller via Bluetooth.<\/p>\n<\/div>\n\n\n\n

A robust wheeled hard case is included for safe storage and transport of the system. A tube is provided to hold the three poles.<\/p>\n<\/div>\n\n\n\n
