Here's a more detailed look:
DIGITAL DIVE COMPUTERS
DETAILS: Hollis DG03 dive computers made by Pelagic Pressure Systems. The computers have serial numbers 100 through 1142 that may be used with integrated transmitters that monitor tank pressure. The round black 2-1/2 inch diameter computer has a digital screen and is worn on the diver's wrist like a watch. The name of the product, Hollis DG03, is printed on the front of the unit and the serial number is printed on the back of the unit. These computers allow scuba divers to measure the time and depth of a dive. Only dive computers with software labeled Revision 1A, viewed on the computer's display are included in the recall. They were sold from July 2011 through May 2013.
WHY: The dive computer, when used with an optional integrated transmitter, can malfunction and display an incorrect tank pressure reading to the diver. A diver could unknowingly deplete their air supply based on the reading, resulting in drowning.
INCIDENTS: Two reports of dive computers malfunctioning. No injuries have been reported.
HOW MANY: About 1,000.
