The anti-clutter sea control is often referred to as STC (Sensitivity Time Control) which decreases the amplification of the receiver immediately after a radar pulse is transmitted, and progressively increases the sensitivity as the range increases. A common mistake is to over adjust the A/C SEA control so that the surface clutter is completely removed. By rotating the control fully clockwise, you see how dangerous this can be; a dark zone is created near the center of the screen and close-in targets can be lost. This dark zone is even more dangerous if the gain has not been properly adjusted. Always leave a little surface clutter visible on the screen. If no surface clutter is observed (on very calm water), set the control at the fully counterclockwise position.

OBS

Turn clockwise to increase sea anti-clutter (STC, Sensitivity Time Control) effect, and counter-clockwise to decrease sea anti-clutter effect.
