Two new Fitbit writsbands set to evolve the product line

Activity tracking wearable firm Fitbit have today announced the impending availability of two new models, including a replacement for the company's best selling Charge HR wristband.

Both products will feature an evolution, not revolution of what's come before, with Charge 2 set to rollout new software based features like connected GPS, multi-sport tracking, cardio fitness feedback and reminders to move. Enhancements to the band itself include a larger, easier to use display and the option for replaceable bands. The new display-less Flex 2 is also set to get some new attention thanks it's swim-proof design - a first for the company.

Charge 2 is available in Australian stores right now, with a global launch next month, while Flex 2 will be available both here and abroad in the coming weeks.
