				Can some explain the use if the CNM and when or why it would come in  handy while on the water?  The small amount I have found so far is not helping to understand what it is.   THX

				thx NK,  I use course up and was reading through some things on the CD and found CNM.   It spoke of waypoints and I just didn't understand how it could help on the water.
 
 Learning how to GROUP waypoints now depending on what lake I'm on.  Just saw that and was curious.
 
 
 thx again
