[QUOTE="cronhelm, post: 353, member: 98"] The GPS ranging method generally requirs that the fixes be taken beforehand. However with a good military map it should be possible to get reasonably close by entering coordinates off the map. Most people hunt the same areas so it should be a simply matter to collect data points over time. The program can calculate the range from one firing position to 30 Target Reference Points. More if you feel like doing some minor modifications to the spreadsheet. The spreadsheet requires that a single wind direction be entered and from that the corrected windage (taking angle into account) is calculated for every TRP. The spreadsheet also compensates for angle and can be used for moving targets. I have a Cassiopea handheld computer with an LCD screen that is easy to see in broad daylight. Once the gps data points are entered this thing is the cat's *** for ranging and shooting to or near known positions. The spreadsheet can calculate ranges as quickly as you can enter the coordinates of the firing position. Peter Cronhelm [/QUOTE]
