There’s a huge range of customisation options. You can set the compass to point to true geographic, magnetic, or grid north. Lots of configuration profiles are available, for hiking, geocaching, running, mountaineering, fishing, sailing and more. These optimise the settings and views for the activity in question, for example putting the geocache entry at the top of the main menu after Start GPS. You can create your own custom profiles, too. This is a particularly handy feature, as the wealth of menu options can be hard to hunt through otherwise.
Where the fenix particularly wins out over handheld hiking sat-navs is in battery life, however. Most handheld models will give you at best 8-10 hours of usage. In regular GPS mode, the fenix will operate for 16 hours, but there’s also an UltraTrac option that only records one track point every minute, to save power. In this mode, the GPS will last 50 hours. Since the fenix will operate in pure watch mode for up to six weeks, you could get close to a week of seven-hours-per-day hiking in UltraTrac mode between charges. The fenix also supports WAAS for more accurate positioning, but this is currently only operational in the US.
With all these capabilities, the fenix is a chunky beast. We also wouldn’t say it has the rugged good looks of the best Casio G-Shocks. However, it is a solid device, rated waterproof to 50m. The large buttons are also easy enough to use when wearing thick gloves. Aside from the heart-rate monitor, the Performer Bundle also includes a natty alternative terracotta orange wrist strap, which can be attached instead of the standard black strap to show off that you have the slightly more expensive model.
You can download tracks and waypoints to a PC or upload data to the fenix, with ANT , Bluetooth and wired connections all supported. However, no ANT receiver is included in the box, with just a USB cable supplied for data connection and charge. This hooks on the back of the watch, latching onto exposed contacts. Although the fenix is compatible with Garmin’s Connect online workout tracking service, the primary desktop management software is an app for Windows and Mac called Basecamp. A version of Basecamp is also available for iOS, although it is only compatible with the iPhone 4S and above. Using Basecamp, you can view your fenix tracks and waypoints on its simple map, a slightly more detailed global map, or optional extra maps, but annoyingly not Google Maps, although you can send waypoints to Google Earth.
You can also use a browser plug-in to send various waypoint files to the fenix, in particular geocache data. So you can use the watch to help you find these hidden treasure troves. The watch supports the basic information about and description of geocaches, including hints. But the 70 x 70 pixel screen doesn’t have much room for text, making this very hard to read, although you can scroll through using the watch buttons. Nevertheless, its exemplary locational abilities mean it does a very good job of directing you towards a cache.
The Garmin fenix is packed with useful functions for the serious hiker or mountaineer, although it does have a major drawback – its price. At £349 for the watch on its own, or an extra £30 for the Performer Bundle, it’s more expensive than any of Garmin’s Oregon range, where the latter’s touchscreen and topographic map-viewing abilities make them more appropriate for general orienteering and hiking. But if your outdoor activities require the long battery life, exercise features and convenience of the fenix, it’s a tempting proposition.
