[QUOTE="GPutt33, post: 770574, member: 58767"] First post here, so I hope I'm welcome. I've been using GPS's since the very first civilian Magellan came out. I became kind of a GPS geek I guess and have ended up as an instructor for sheriff depts, search and rescue squads as well as a few corporations. All of the info posted so far is correct. The WAAS system has increases the accuracy. If you have a screen showing active satellites most units will show you the WAAS satellite location as well. I do like setting the unit up on the WGS-84 grid because this compatible with Google Earths coordinate system. I like setting the coordinates to read in Decimal Degrees because this makes it much easier to input not only in map programs but is also the only one you can easily use in Excel. Saving a waypoint of your shooting bench is the first step. Proceed on out to where you want to set up your targets and go-to your saved bench waypoint and it will give you straight line of sight accurate to within 15'. Just make sure when doing this for accuracy you have optimal sat coverage at the time, it does change constantly. The worst piece of info off a GPS is elevation. Think about standing in an egg with 15' out to the shell. The narrow pointy end of the egg is above your head and may be off by as much as 100'+. Make any sense? Hope so :) [/QUOTE]
