PRODUCT NAME : SPERRY MARINE SAFE COMPASS DISTANCE KNOTS SPEED 5 TO 30
COMPANY NAME : SPERRY MARINE
MODEL NUMBER : ANS244-30-C

PRODUCT DESCRIPTION :

The Sperry Marine Safe Compass Distance Knots Speed 5 to 30 likely refers to a specific model of Sperry Marine’s speed log or compass system, designed for use on vessels to accurately measure speed and distance traveled. These systems are crucial for determining a ship’s velocity in knots (nautical miles per hour), especially in various maritime conditions where precise speed and navigation data are necessary.

These systems work by emitting radar signals to the seabed or the water’s surface and then measuring the Doppler shift in those signals. The system then computes the vessel’s speed, typically in knots. The range of 5 to 30 knots mentioned could refer to the operational speed range of the device. Speed logs in this range are typically used on vessels like cargo ships, tankers, and even military vessels to monitor speed for navigation and safety purposes.
