GPS evolved. The Soleus GPS FIT 1.0 has a new highly ventilated strap, simpler 4 button user interface, and much larger numbers on the customizable display viewing area. Simple and easy to use, the Soleus GPS FIT 1.0 will allow runners to accurately track their Speed, Pace, and Distance. Auto lap splits at every mile and the "always on" night light mode helps for late night (or early morning) runs and training. Our GPS Fit 1.0 knows exactly where to find the global positioning satellites orbiting miles above the Earth that will help you keep track of your run, walk, hike or bike. You can even personalize your Soleus GPS Fit 1.0 by inputting your personal data to track calories burned during your workouts.
