Getting Elevation With the Suunto Core Green Light
The Altimeter/Barometer Mode of the Suunto Core gives 3 different views. Altimeter, Barometer and Depth Meter. Unlike GPS, the Suunto Core’s Altimeter/Barometer calculates information based on barometric pressure or known reference values. Air pressure changes from location to location, so it is required for the user to calibrate the starting altitude or barometric air pressure before commencing on an activity where the user requires accurate altitude or barometric pressure information. Most outdoors enthusiasts that venture off into the mountains are aware of this and elevation information is usually posted along trail markers or on topographic maps. It is important to check and calibrate the watch with the maps and sign posts as you go.
During my trip to the outdoors of beautiful British Columbia, I spent a lot of time logging runs down some of the best chairlift accessible mountain trails on the planet. I used the Altimeter function during those days to measure and log how much vertical change from the starting point (bottom of the chairlift) we were getting each day. The numbers were staggering at times! We were getting some serious vertical!
Here is a summary of the information recorded by the Suunto Core Green Light for the four days I went mountain biking:
I wasn’t too concerned with the accuracy of the Altimeter as I knew the chairlift would take me to the top and I could ride back to my condo in the afternoon. I’d be pretty picky on altitude accuracy if I was going for a hike into the mountains. Knowing accurate information when hiking in the mountains helps people make decisions on how much further to go or when to make camp. There were certain mornings were I would calibrate the Core’s altimeter to the elevation posted at the bottom of the chairlift and there were other mornings that I forgot. I found that on the days that I didn’t calibrate the Altimeter, it would be out on average about 30-40m from the posted elevation.
It was interesting to check out and compare the data over the 4 days of riding. We managed to peel of a staggering 37 runs and descending 18,876m of vertical over the 4 days!
