If you are going to use your Garmin GPSmap60 as a mapping reciever, here is a quick tutorial on how to set it up so that you can get the most accuracy out of it. This tutorial is to set up your track log to record a postition once every second, some might think that this is to much but unless memory is an issue i try to alway collect all the data I can, at the best resolution possible. This way it might possibly save you a trip back out to the field because you already have the best data you can collect. OK to get on with it, First turn on your GPS unit and bring up the main menu.
Here you will select the Tracks icon, this will take you into the tracks access menu.
At the tracks menu page you can; turn tracking on/off, clear your track log, save it, trackback, and access the track setup screen, which is where we want to go.
Use the drop down menu to select the TIME interval, and then set the interval to 1 second.
I also make sure that the Wrap When Full box is Not checked. If you think that you will run out of memory adjust the time interval possibly to 2 seconds. If this is not an option you will have to make arrangement so that you can download your gps in the field when it gets full.
