in Africa?

He keeps thinking I’m in Africa and then I’ll switch back to the states. I don’t know what it’s doing. I can’t depend on it.

Anchor! Drag alarm

Good, but only as good as the gps on your device. For my I-pad gps is pathetic, so I get some false alarms. I-Phone works better.

Simple, highly functional, remote monitoring capable with two phones with wifi or cellular signal. Reliable peace of mind at anchor in my palm with all my other navigation tools.
This app has given me a heads up when I was dragging long before I would have realized more than once. (Voyaging captain of 35 years. 120,000+ blue water miles)
