ðµBang for the Buck 3.5 Before I tried out the Fenix 6 Pro Solar, all I knew is that itâs one of Garminâs more maximalist models thatâs âtested to U.S. military standards for thermal, shock and water resistanceâ and priced at $799.99. Admittedly that description sounded a little excessive for my purposes as most of my activity comes in the form of running. But I was curious about how user-friendly and useful in general its many features would be. And it delivers to the military standards â but it's a great fitness wearable for athletes or adventurers who obsess over data, tracking, mapping, and more.Â
