[Primus]

I'am using my Core regulary during the free diving to depths up to 20 meters, but maximum depth which is measuring by Core is 12 meters. However I never press any button while underwater, although I find an information (on Suunto web pages) that Core has UW buttons.

The official rating for the Core is 30 meters.
