Just to add another point, comparing the GM-210 with the BU-353, the reported elevation is different by 30-100 feet (i.e. BU-353 said I was at ~140 feet, GM-210 said I was at 40 feet. I was right on the beach, and I can see the water, and it could NOT have been 140 feet below me. Even with tide and whatnot, the difference is remarkable. I'll do a drive this weekend with my laptop and the carpc to run both GPS receivers at the same time. I hope to put up some pictures to examine the difference in reported position and elevations.
