Description:
Also known as Fitbit FB501BKL, the Surge can only be bought in fixed colors and sizes, since its wristband is non-replaceable, unlike other models with interchangeable bands, while it nets a 7-day operating time with GPS tracking turned off, 10 hours in GPS mode, and fully charges within two hours. It also layers a Gorilla Glass cover on its monochrome LCD display and banks on a 5-ATM water resistant encasement to protect its innards (The device is not submersible in water despite its ingress protection rating).
Also known as Fitbit FB501BKL.
