      Brian,

      Thanks for the offer, but the Garmin will accept UTM coordinates, that isn't the problem. The problem is trying to determine an accurate UTM coordinate inside the grid reference box.

      Say a peak like the "Priest" is inside a grid bounded 40-45 on the left and right, and 85-90 bottom to top. I can't figure out how to measure the distance from the left side and up from the bottom to come up with the UTM coordinates. If it was a LAT/LONG grid I could measure the physical distance and use LAT scale to calculate the LAT/LONG. I learned here at work that LAT/LONG isn't accurate enough, so the armed forces have gone to UTM with the goal of getting down to 'rain drop' accuracy. (Granted the hole will be bigger than the drop, but boy can we measure accurately - smile.)

      I can measure miles/meters from the edges of the grid, but how does that convert to UTM I haven't figured out yet.

      Thanks all for the help. The answer is out there.

      Tom
