The DG03 dive computer problem that has been described to Dive Gear Express is that under some circumstances when the DG03 is used with a high-pressure transmitter, the DG03 does not update the displayed cylinder gas pressure in a timely manner. This could cause the diver to believe they have more breathing gas in the cylinder than is actually present. Note this issue applies only to the Hollis DG03 dive computer (Hollis Part Number 204.2360) when used with a wireless transmitter, and we are told it does NOT apply to any other model dive computer or to the wireless transmitter.
Hollis is in the process of implementing a Voluntary Recall on the DG03 dive computer in cooperation with the US Consumer Product Safety Commission and we are told by Hollis that in approximately one week the
Hollis Gear website will contain detailed information explaining action to be taken and procedures for upgrading the firmware in DG03 dive computer.
In the meantime, Hollis has not provided us with any guidance regarding your continued use of the DG03. We recommend you do NOT rely upon the DG03 to monitor scuba tank pressure, or to estimate remaining volume or duration of breathing gas supply. Relying upon such information from the DG03 before this issue has been addressed could result in your serious injury or death.
