I'm from Texas, so I haven't paid much attention to the altimeter on my Vista HCx until last week. I did some hiking in the Rockies and got interested in tracking my elevation.
My altimeter, without calibrating, was over a thousand feet off when using just the GPS elevation, even though I was tracking several satellites. I calibrated to a known elevation (9405ft) and began my 3 mile round trip hike with about 400 ft of elevation change at the halfway point. When I returned to my starting point, my altimeter showed 9475ft...doing the math, that's 70 ft off!
I had similar or worse results in different areas around Rocky Mtn Nat'l Park over the next few days.
I've been very happy with my Vista's lateral accuracy, so I was really surprised that the altimetry is so poor. Am I being too picky? Are there tips or tricks to the altimeter setup? Anyone else having this issue with the Vista?
Thanks
