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.
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.
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.
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.
An Android app 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.
A robust wheeled hard case is included for safe storage and transport of the system. A tube is provided to hold the three poles.
