While not without its flaws, Garmin’s Vivofit fitness tracker is unique in offering a truly waterproof design, the ability to pair with a heart rate monitor, and most notably, over a year of battery life via a standard watch battery. When it launched a couple years ago, the tracker and an optional chest strap heart rate monitor would have set you back $170, but now, you can get both for just $47 with promo code SUMMER. Note: Not valid on the black model.
Don’t want the heart rate strap? You can still get a bare refurb for $30.
