A scuba black box that you don't have to die for (NWDExpo)

Sensus Ultra dive data recorder from Reefnet Inc. is just a tiny fob (1″x1.3″x1.75″) that attaches anywhere to your dive equipment. It records your dive time, temperature, depth and accent rate for more dives in more detail than most any dive computer. It takes measurements every 10 seconds with a depth resolution of .5 inches. With a storage capacity of 1500 hours it will hold more dives than most recreational divers make in a lifetime. Unlike most dive computers, the Sensa package includes PC and Mac software and the cable. We paid over half the cost of the entire Sensa package ($150) just to purchase the proprietary cable for our Suunto computers.
