My Legend, and Sportrak with a BOO BOO at the Willard Benchmark MR0719 *********************************************************************** MR0719 DESIGNATION - WILLARD MR0719 PID - MR0719 MR0719 STATE/COUNTY- UT/BOX ELDER MR0719 USGS QUAD - MANTUA (1991) MR0719 MR0719 *CURRENT SURVEY CONTROL MR0719 ___________________________________________________________________ MR0719* NAD 83(1994)- 41 22 57.96612(N) 111 58 28.42627(W) ADJUSTED MR0719* NAVD 88 - 2978.1 (meters) 9771. (feet) VERTCON MR0719 ___________________________________________________________________ MR0719 LAPLACE CORR- 10.56 (seconds) DEFLEC99 MR0719 GEOID HEIGHT- -15.97 (meters) GEOID99 I downloaded the coordinates off this datasheet from the Geocaching website into ExpertGPS. On the mountain peak, I placed the receivers as displayed in the picture, and recorded three waypoints over the course of 10 minutes. The distance from the waypoints according to ExpertGPS are: Legend: 8.9 feet, 6.9 feet, 1.9 feet Sportrak 3.0 feet, 3.0 feet, 2.2 feet Both receivers showed great accuracy, which would enable you to easily find this benchmark just by following the GPSR. The Sportrak was the most accurate overall, and the most consistent. Of course being on a mountain top, I had about as good a view of the sky as you're going to find in these parts.
