This chapter covers the use of waypoints on Garmin receivers. Capturing your position as a Waypoint Planning Ahead Waypoint Entry Updating Waypoint Data Viewing Waypoint Data Deleting Waypoints Distance to Waypoints Proximity Alarms Tips and Tricks Waypoints are used to store and remember locations that are of interest to the user.They are often used to store intermediate turns and intersections that help define a route to a particular destination.On the G-III family and emap you first save the waypoint and then you can average by selecting this option from the local menu on the waypoint display screen.(Please see more information on averaging below.) If you are using dgps you can still average the position but the improvement will be much less since dgps is already more accurate.On some units it will automatically use the lowest available number but and on many others you can force the number sequence to continue from wherever you wish.To do this just name a waypoint from the number sequence.
A position marked in this way is designed as a safety feature for boat use when someone might actually fall overboard.
Similar to the waystations used by pony express riders as stopover points waypoints mark significant places on your journey.
In some documents and gps receivers these may also be called landmarks.
You simply hit the MARK key, on the G-III, etrex, 76, and emap press and hold the ENTER key, and the waypoint entry form will appear.
The location you were at the moment you pressed the button is already saved in the waypoint information on the form so even if you are traveling at 65 miles per hour down the freeway you can reliably capture a single point with the press of the button.
