[QUOTE="Dave King, post: 352, member: 3"] Darryl Yes, the GPS works as a ranging instrument but as you suspected, you must get a position fix at the intended impact site. The GPS will get a good fix to within 5 to 7 yards on both ends of the flight path. The program Peter Cromhelm has on his site, the "Thing", lets the user enter multiple positions where an animal/whatever may present itself. It also has a place for the position of the shooter. By using these positions the program gives distance and direction to the various target positions. You can also enter the wind direction and value from the shooter position to one 'main' target site and the program calculates all other wind values based on the single reference wind. (Assume a single source/direction wind.) It's a fairly simple thing, I hunt in areas where I know the animals will enter the fields and clearings at a known location. I pre-fix these locations with the GPS. I also can select any location I desire as my firing position. All I need to do to get a target distance once I've setup my area is select my firing position and the correct critter position, the program has the distance, come-up data and wind setting (providing I've entered wind data). It's probably more value for a varmint shooter but works well for me for deer. I believe Peter has the program on a palm computer and takes it into the field with him. I've used it on a palm type HP Jornada handheld computer and it functions great but the LCD isn't backlighted so it's nearly impossible to read in bright sunlight. A backlighted LCD is pretty much a requirement for the handheld, the Casio E-115 Cassiopea is a backlighted model. [/QUOTE]
