At $170, Highgear’s Alterra comes with the requisite adventure gauges you’d expect at that price, including an altimeter, a barometer, a digital compass, a thermometer, and more.
Both have a digital face with an altimeter to read your altitude, a barometer for assessing weather, and chronograph functions for tracking splits during workouts or competition.
But the Alterra has a few features the Suunto leaves out, including a digital compass, a thermometer, and a “ski chrono” function for tracking downhill runs.
The $289 Suunto t6, in turn, has exclusives like a heart-rate monitor and an accompanying computer program for analyzing workout data. Highgear does not have either. (See my full review of the Suunto t6 here: thegearjunkie.com/heart-rate-monitor-watches.)
On my trip last month to climb on Mount Shasta, I put these two watches head to head, assessing usability and comparing altimeter readings at various points on the mountainside. The Highgear fared well against its more expensive competition, with few performance discrepancies between the two.
The Alterra’s altimeter was accurate within a 20-foot range, which is good enough for any type of mountaineering.
Its digital compass worked fine, too, spinning to all points with little hesitation, though calibrating it is a slight annoyance that takes about a minute before each outing. I also still just have trouble trusting anything but an analog compass, and thus was loathe to only rely on the Highgear watch, however silly. It’s sort of like always bringing matches, when a Bic lighter might just do the job better.
Overall, compared to the t6, Highgear gave the more-pricey Suunto a literal run for its money in this test.
