Data-enabled devices to help you climb every mountain
HOW WE TESTED
To access the accuracy of the altimeter in each of these trekking and climbing tools, we took all five devices on board Europe's highest railway to compare their readings with the known elevations of each station. The Jungfraubahn, which celebrates its centenary this year, winds through the Swiss Alps from Interlaken station at 567 metres above sea level, to its highest point, Jungfraujoch station at 3,454m. The graph below reveals how closely each altimeter correlated with the actual altitude of each station. We also assessed each product's design, functionality and value for money.

To assess accuracy, we plotted the actual station altitudes against those recorded.
