HP Wireless Transmitter for DG03/DG05

This small wireless transmitter screws in to the high-pressure (HP) port of a first stage regulator and can communicate with the Hollis DG03 and DG05 dive computers to allow them to display the cylinder gas pressure (in PSI or BAR) without the use of the typical HP hose. This feature is often referred to as hoseless 'air integration' but since the dive computers are capable of handing a variety of breathing gases the term air integration is a misnomer.

Each transmitter has its own unique ID and up to four transmitters can be linked to a DG05 or up to three transmitters can be linked to a DG03 computer. The transmitter is charcoal in color, rated for depth up to 330 feet / 100 meters, and has a user replaceable CR2 battery. As supplied, the transmitter is suitable for use with any breathing gas mixture including 100% oxygen.

HP Wireless Transmitter An antenna inside the dive computer receives the signals when it is positioned within 6 feet of the transmitter and within a zone parallel or at a 45 degree angle to the transmitter. Best reception is achieved when the dive computer and transmitter are within 3 feet (1 meter) of each other. During a dive you may at times move the dive computer so that is out of the signal pattern of the transmitter, resulting in a temporary interruption of the link. The link may also be interrupted if the dive computer is within 3 feet (1 meter) of a running DPV or after a strobe light flashes. The link will be restored within 4 seconds after the dive computer is reoriented, moved back into range, or the interference clears. For technical diving, Dive Gear Express recommends following the best practice of also including a standard analog SPG on the regulator as a backup.
