Marking and Editing Waypoints
Now you are ready to enter your geocache coordinates. On the Garmin GPSMAP 64, press the Mark button. If you are using a different model, refer to the owner’s manual to learn how to mark a waypoint.
After marking a waypoint, the GPS receiver takes you to the waypoint edit screen. By default, many GPS receivers assign a series of numbers for waypoint names, such as 001, 002, 003, and so on. Unfortunately, this naming convention sometimes causes problems when working with GIS software. It is a good habit to give your waypoints descriptive names to avoid this issue.
Change the name of your waypoint so that it matches the name of the geocache. On the Garmin GPSMAP 64, use the rocker pad to select the name and press the Enter. On the edit screen, enter your geocache name.
Next, select the location option on the waypoint edit screen.
Enter the coordinates for your geocache.
When you are ready, press enter. Then, select Done to save the waypoint.
Repeat these steps for each of your geocaches. You should attempt at least three. You may want to consider adding an extra geocache in case you have trouble with one or more. After entering your geocaches, power down the GPS receiver to save battery life.
