how do you guys use your gps to get on your waypoints,do you get close and stop short of the waypoint or try to get on it and drop a bouy, seems like everytime i get close,is all of a sudden its behind me, just cant figure it out, ive got some good numbers from friends but right now they arent doing me any good..also do i need to have the waas turned on? not even sure what it is,i know its supposed to be more accurate so i figured it owuld be on all the time, but was looking through settings on my 520 i think may be the1197 and seen a link to turn on waas? any tips for using the gps isw apprerciated...just would like to use it more then to know what general area im in and how fast im going... thanks
