Why We Like The Suunto 9 Baro

Designed to balance battery saving and accurate GPS tracking, the Suunto 9 Baro is an invaluable tool for the dedicate long-distance athlete. With three distinct battery modes, this sport watch assures long-lasting performance when we head out on the trail. It has 25 hours of battery life with Performance mode, 40 with Endurance, and up to 120 hours with Ultra mode. The Suunto 9 also sends smart reminders based on personal activity history to always charge up before the next run. If the battery runs low in the backcountry, the watch will automatically suggest switching to a different training mode to conserve battery life.

One of the biggest problems with ultra athletes and GPS watches is battery life. On longer runs, GPS frequency is often reduced in order to preserve battery life, which may lead to a less accurate reading, especially on technical trails and tight switchbacks. Suunto's response to this problem is their FusedTrack algorithm. FusedTrack fills in the gaps of waning GPS signals with motion sensor data, ensuring both a more accurate reading and a prolonged battery life for heading out for hours at a time.

Of course, extended battery life is only so great if there are features worth keeping charged, and with the Suunto 9 there certainly are. It has a built-in heart rate monitor in the wrist to help monitor an active performance during speed workouts and high-altitude runs. Speaking of altitude, this watch has a FusedAlti altitude tracker that works similarly to FusedTrack, combining GPS and barometric altitude for a more accurate reading. Weather tracking gives temperature readings and storm warnings, while speed tracking, plenty of log storage, and over 80 sport modes help monitor work outs of all kinds. The new Outdoor watch face displays atmospheric and compass data for bearing through tough sections.

Finally, it wouldn't be a good performance watch if the watch itself wasn't tough. A durable sapphire crystal face stands up to scratches and trail abrasions, while a silicone strap stays comfortable and offers a secure grip. For rainy weather and pool running it has 100m water resistance ensuring we can log an accurate workout in the water.
