My old Suunto would record the number of dives, but the dive information was not kept for overwriten dives.Thank you for the reply. When I connect my Zoop to both MacDive and Suunto DM5, all dives on the Zoop are recognized. Again DM5 only recognized a few dives. My only reason for looking at dive apps other than MacDive is the issue with MacDive not exporting to excel. No answer from the MacDive forum.
