Note: On short range scales, do not set the Sea Clutter control so high that all clutter is removed, since this could prevent you from seeing close-echo targets.

The SEA control can be set to Auto-Harbor (default), Auto-Offshore or Manual mode. In Auto-Offshore mode, the Pathfinder Plus Radar optimizes its settings to account for the effects of sea clutter. In harbors or close proximity to land different auto settings may be necessary to cater for the effects of land clutter. To avoid losing small targets it is therefore advisable to set the Sea control to Auto-Harbor mode. Alternatively, set both Sea and Gain to Manual mode then adjust the settings to ensure that all close small targets are visible.

Note: Because the SEA control affects the gain, you may need to manually readjust it if you manually change the Gain setting.
