DS-860
The Furuno DS-860 is a marine speed log. It is normally installed on the bridge with hull-mounted or networked speed sensors. It is designed for speed data for navigation, radar, ECDIS and recording systems. The operating principle relies on measurement of vessel speed by the sensing principle fitted to the model. The supplied entry gives no additional verified capacity, pressure, power or dimensional figure for this model. Compared with neighbouring models, the relevant differences are speed-through-water/ground capability, sensor technology and interfaces; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on transducer/sensor condition, calibration, outputs, alarms and comparison with independent data. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.

Service & Maintenance
Verify the equipment against an independent navigation reference where practicable, inspect antennas/transducers, cables and power supplies, and confirm required sensor inputs and alarms. Check data distribution to dependent bridge equipment and review calibration, chart or configuration status appropriate to the device. Use vessel procedures and manufacturer tests for acceptance.
