Measuring grade on hills
Anyone have any tricks? I have a new Garmin 2595 which has all the data but I haven't studied long enough to see if I can display grade.

The Garmin dezl560 and 760 gps devices will display grade. I've not used the feature, so I can't comment on the accuracy.

I used the grade feature of the deal 560 yesterday, as we drove up the Black Mountain climb on I-40 in North Carolina. It seemed to be very accurate. Except for a brief 5% and even briefer 8%, it stayed between 6% and 7%. The hill is listed as a having a 7% grade.
On the long descent into Tennessee, the device gave no grade. I surmise that, because of the mountains, it was receiving signals from only 3 satellites. As aside, 3 satellites is sufficient for location, but 4 are required to measure elevation.
