The 1.2 inch sunlight-readable Garmin Chroma Display promotes easy reading in bright outdoor conditions, with a high-strength sapphire lens that withstands regular use and abuse. Helpful upgrades make the Fenix 3 HR Training Watch a great candidate for high-level endurance athletes training for upcoming events and outdoor enthusiasts maximizing every available opportunity for exploration and physical fitness.

Improving its signal reception, the omni-directional EXO antenna tracks both GPS and GLONASS satellites for quickly locking onto your precise location. The altimeter, barometer, and 3-axis electronic compass help you navigate through remote stretches of forest without getting lost. GPS track logging creates a "bread crumb trail" as you move across desolate stretches of wilderness, allowing you to navigate back to your starting point with the TracBack feature.

The Elevate wrist heart rate technology measures your heart rate without the use of bulky chest strap monitors.

Advanced running dynamics measure vertical oscillation of your running movements, ground contact time, cadence, and stride length for monitoring your running symmetry.
