The P1920 Steering repeater gives a visual indication of heading from both true and magnetic inputs.
The requirement is for the helmsman at the steering position to read the compass and 15° to either side of the lubber line. To achieve this the P1920 has both a numerical and a digital tape indicator.
The digital tape copies the feel of looking directly at the compass. It is helpful as it gives the helmsman and other members of the bridge team good awareness of the rate of turn and the difficulty level of maintaining heading.
