Hollis Gear is recalling about 1,000 U.S.-made dive computers because an optional integrated transmitter can malfunction and display an incorrect tank pressure reading to the diver.

Although no injuries have been reported, the malfunction could cause a diver to unknowingly deplete their air supply based on the reading, resulting in drowning. Hollis has received two reports of dive computers malfunctioning.


Consumers should stop using the recalled dive computers until the unit's operating system is upgraded to revision 1B. Consumers can download the upgrade from the firm's website or contact an authorized Hollis dealer for assistance. 

The recall includes Hollis brand DG03 dive computers with 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.

The computers were manufactured by Pelagic Pressure Systems of San Leandro, CA in the United States and sold at authorized Hollis dealers nationwide from July 2011 through May 2013 for about $500.
