One of the most innovative features of SIMS, Direction Finder is one of the main tools for finding people.

If people have a handheld radio, an EPIRB (Emergency Position Indicating Radio Beacon) or a PLB (Personal Locator Beacon), Direction Finder will pick it up.

As well as displaying a bearing to the signal source, Direction Finder will draw a line on the chart to show where the signal is coming from.
