Fitbit Surge Fitness Watch (Large): Built with GPS tracking and continuous, wrist-based heart rate monitoring, Surge displays real-time workout stats like distance, pace, elevation climbed, and heart rate intensity, so you can make the most of your training.
Will change review to 5 stars once GPS issue is straightnes out. At this point, this is an overpriced step counter. They claim they have a new firmware update coming but it has been 2 months since my purchase. The MAIN reason I purchsed was the GPS function and strapless heart rate function. Heart rate function is sporadic and GPS shuts off after .2 miles or less. Looking forward to firmware update
