Although pricey at £470, there’s very little the Fenix 3 Sapphire HR can’t do, whatever your pursuit. You get GPS and barometer-fuelled global location, altitude and pressure figures that are easy to summon up in various formats, an effective digital compass, and the ability to record myriad activities as well as track a boggling array of stats from heart and recovery rates to stress levels, cadence, stride length, lactate threshold and many more. You’d suppose the device would be convoluted to use and with poor battery life as a consequence, but neither is true. Deliberately approaching the Fenix without consulting the manual, I found instinct was strong enough to unlock 99% of features without trouble, while moderate use has seen a need to charge it every two weeks on average (although a full 12hrs+ of GPS measuring a mountain route will drain it pretty comprehensively). At 86g it’s relatively heavy, but the silicone strap is well judged and it still remains possible to wear it whilst jogging. The crisp scratch-resistant display is superb, and the world of data it can display fascinating. If the price is a barrier, also consider the lower-spec Fenix 3 (£380).
VERDICT: Big and pricey, but supremely capable and expertly designed.
BEST FOR: Multi sports.
