Anchor watch
There will be times when you're anchored that the current may cause your vessel to drift. You can set an ANCHOR WATCH alarm on the X100 that notifies you when you drift too far.
Once set, a virtual safety zone is set up around your anchor point. If your boat drifts beyond this area because of wind, currents, or other factors, ANCHOR WATCH will alert you with a pop-up or alarm. Make sure you turn on anchor watch after the boat is anchored and not drifting. It’s a great way to have peace of mind, knowing you’ll be notified if your vessel starts moving unexpectedly.
Below shows you how to turn ANCHOR WATCHON or OFF.
