FR610 tracking skiing/snowboarding

Has anyone had any experience in using FR610 to track snow activities? I hear you should switch sport to cycle, bound to be better than fiddling with an iphone app (which I alway forget to stop when ettog on the lift) but I wonder, with its shaky waterproof status, how much snow it can take...

Shaky waterproof status?  First I've heard!  Anyway, I've not used the 610 skiing but I did use the 305 (on cycling mode) without any problems.  Not sure what sort of activities you're planning, but it stayed a lot drier under the sleeve of my skiing jacket than it would do running in the rain.  Should be fine, I would've thought.

The Forerunner 610's waterproof rating is IPX7 - which is waterproof to 1 metre for up to 30 minutes.  http://hrm-reviews.com/is-your-heart-rate-monitor-waterproof/ Don't know why its such a low level when even a lot of cheap ones are waterproof to 50 metres.

However it should still be fine for skiing and as Phil says its probably under your sleeve anyway. 

you were right, it coped very well.

I did much worse not remembering to pause after the ride
