Todays smart phones have a hardware that is mind boggling. Why not put it to useful use?
"My Anchor Watch" uses the GPS on your smartphone to monitor your boat's position. If the boat moves outside of set limits, the program will alert you immediately. There are no more sleepless nights when you worry about weather your boat is dragging or not. Keep the phone next to where you are sleeping and a quick glance will asure you that all is ok.
If the boat drags out of the predefined areas, it will alert you in any way you decide. Flashing text, sounding alarm or even send an SMS to another phone.
These functionllities are not available in any other anchor watch! To get it at this price is only improving matters. Isn't technology advances wonderful!
