Well the rumours of a new HR-SWIM strap appear to be FALSE. There is a new HR strap with an apparently extended battery (CR2032? is the same surely) life but not for under the water.

Although if you look at both links you will see the pods appear different. The one from the GB shop is NOT the HRM-RUN pod. Indeed the pod seems to have a slightly unusual shape. Maybe the rumour is still alive 🙂 [or maybe it’s just the non HRM-RUN pod !!!]
