Your fleeting heart

The waterproof Mz-switch is an awfully versatile activity tracker once you get to grips with it

Chest say no

If there’s one criticism labelled at chest straps, it’s that it feels like you’re being kitted out for Laser Quest every time you want to record the results of a lockdown walk. The Mz-switch makes you feel like far less of a twonk.

End of the mode

If you’re mixing things up with a wrist-based PPG run to get the blood pumping before switching to the ECG chest strap for a nifty club pump, a quick press of the module’s button switches between modes.

I wrist again

That’s because the PPG wrist strap is for non-grip activities like running and swimming. For exercise involving heavy wrist movements, like racket sports, rowing or strength training, switch to the PPG forearm or ECG chest strap.

All dried out

In theory this means no downtime during the switch. In practice it can be a little fiddly, especially as the conductive patches on the chest strap sometimes need moistening before the connection will kick in.
