Just purchased a zoop and used it over the weekend for the first time, read manual and took DCT course... Set a dive time alarm to 45 min but i heard nothing at 46 min, also on importing my logs and looking at the DP i apparently exceeded my save ascent rate, (this was a 34 foot drift dive), yet again no beeps or alarms. I was wearing a full hood which muffled sound but still i should have heard something. Anybody experienced this issue before, contacted suunto but have not heard back yet.
