Magnetic North

Important: When taking a bearing, the 

watch MUST be parallel to the 
horizon or the data will be 
inaccurate.

This watch will also display the opposite

bearing is used to accurately 
backtrack your direction or determine 
you location on a map

[MODE] to toggle between forward 
and reverse bearings. The icon "    " 
displays for Reverse Bearing

Time Mode

This watch will provide a "compass 

lock" function to secure an 
improtant bearing.  When the      
"        " is displayed, the 
compass reading will not change

intersection of these two lines

    
Use this watch and a protractor to 

keep to a trail
