In this video, I’ll show you how to change units & position format.
If you are a metric or Imperial person, simple way to change those distance settings. Also if you are working on maps, like surveying, search & rescue, police or fire work, you may need to adjust your unit to match the UTM format if you are working with a paper map.
These settings can be restored to the defaults easy enough. If you are just doing geocaching are simple hiking, you have no need to change the position format.
