What is an Anchor Drag Alarm on a Garmin Marine Device?

Several Garmin marine devices allow a user to set an anchor drag alarm to sound when you exceed a specified drift distance while anchored, this is especially helpful anchoring at overnight. It is important to know that when setting the alarm, the GPS location for the alarm is based on the location of your chartplotter, not the location of the anchor. The radius is set by the user from preset options to a custom distance.  

For specific instructions on setting the anchor drag alarm, refer to the device’s owner’s manual, Finding the Owner's Manual for a Garmin Device.
