Thanks for all of the comments and the input. Obviously the general consensus is that GPS units are roughly in the parish as far a distance and where am I is concerned; but with regard to altitude they are effectively pants.
Not all "effectively" pants.
My Montana is quite good at elevation if you let it settle.
When I first got it, I went to a few OS spot heights and placed it on the ground. It was correct within a few feet.
What you can do with many devices, is tell it at what elevation it is at, and then it'll track the ascent accurately ........... plus or minus wind across the breather hole.
I set mine at the elevation of our front drive as I know that from the OS map. It's a menu item in the Settings page.
When I had the Edge705, you couldn't set the elevation, but you could create a waypoint at your front gate, and the waypoint menu allowed an elevation input. As you ride away, you go through the waypoint, and the 705 then flipped to the correct elevation.
