The program "iDrifter" serves the continuous monitoring of the position (anchorfix) for anchoring yachts. The program displays graphically the current drift of the yacht relating to the anchor – selectable either as a radar graph or as a map graph.

For this purpose, the current position in relation to the anchor will be identified once per second and digitized as a dot on the display. As soon as a specific distance –adjustable by the skipper- to the anchor fix will be exceeded, an acoustic alarm will resound.

Pleas note:
"Continued use of GPS running in the background can dramatically decrease battery life."
