Suunto released their BRILLIANT Suunto Spartan Trainer (Aug 2017) – complete with GPS and wrist based HR for almost HALF the price of the Suunto Spartan Sport wrist HR. Same firmware, 10 hours GPS battery etc.

Could be the BEST ever value for money Suunto sports watch.

Fitbit released their new Fitbit Ionic (Aug 2017) ahead of the Apple Watch 3.

The Fitbit Ionic is their first genuine smartwatch with integrated GPS and wrist based heart rate. A couple of key features are 4+ day battery life with up to 10+ hours of GPS use. Our initial review of the Fitbit Ionic has now been published

Garmin released three new products in Aug 2017.

The Garmin Vivomove HR – a hybrid smartwatch, the Vivoactive 3 replacing the Vivoactive HR and the Vivosport replacing the Vivosmart HR+.

The Vivosport will be challenging the Fitbit Charge 2 as the best fitness tracker for 2018 – and with colour display, slimline styling, built-in GPS & wrist based heart rate it’s got a great chance.
