TDD-5 Digital Repeater Compass with 0.1° Accuracy, 24V DC Power, and RS422/RS232 Interface for Ship Navigation
The TDD-5 Digital Repeater Compass is a modern repeater compass featuring compact design and flexible installation options including embedded, wall-mounted, or desktop configurations. This advanced instrument transmits the ship's heading data from the gyrocompass to any location on the vessel.
Utilizing the latest electronic and computer technologies, the repeater compass accurately determines bow and stern lines relative to geographical north, independent of the gyrocompass installation location.
