COROS VERTIX 2

£599.99, coros.com

A brand-new feature on COROS’ very latest rangetopping adventure watch, the Vertix 2, is ECGsensor tech built into the bezel – which makes HRV tests stupidly easy to do. You simply sit still, relax and hold the bezel for a minute. The test reveals an HRV Index score out of 100 and a short guidance message that tells you how relaxed or strained you are, how well your body is recovered and how ready you are compared to your baseline average. Like all HRV tests, for optimum insights you need to take morning measurements at the same time each day. Preferably pre-coffee, exercise and any other factors that may skew your results. We’d have liked an alert to remind us to take the test.
