Style, performance and comfort
M400 is an exceptional blend of sporty design, integrated GPS and advanced training features, along with plenty of options to keep an eye on your activity 24/7.
Driven by goals
Push your boundaries and step out of the ordinary. In the Polar Flow service, you can set yourself targets and reach them - in all the sports you do. M400 also keeps tabs on your personal bests and lets you know when you've made a new record.
Set targets in Polar Flow and sync them to your M400. It guides you through your training and lets you know when to speed up and when to take it easy.
See how your running performance is developing. M400 counts your running index score automatically after every run based on your heart rate and the speed data collected by the built-in GPS.
In Polar Flow you can create tailored views for each sport you do, and choose the data you'd like to see when you train.

M400 is water resistant and good for tracking activity when you swim, but it can't record heart rate in water. That is because the Bluetooth Smart used in the device for transmitting data does not work in water. Polar H7 heart rate sensor transmits data via Bluetooth Smart and via GymLink. GymLink does work in water, but M400 doesn't support it.
