[QUOTE="ChadRack, post: 20695, member: 90"] I think GPS and topographic maps go together great for ranging. I use it to plot locations of deer stands on our lease and also to make sure that they are far enough apart. The units with the position averaging feature work best. UTM is the easiest way to tranfer coordinates back and forth between the unit and the map, but in can be done in DMS if you have an older map. Most local map stores carry the see-thru scales, but you can make one also. I take the difference in the "Northing" and "Easting" and use standard math on the angle to figure the distance. Then repeat if there is a large difference in elevation. I've haven't tested this since they turned the SA off, but accuracy should be in the 10' range now. The more readings you take, the more accurate your answer will be. [/QUOTE]
