Rebreather Accessories


The recreational and technical rebreather world is ever changing. New parts and accessories arrive, old parts get discontinued, and the internet rumour mill is ever churning with questionable information. Give us a call or an email if you have any questions on the latest consumables, parts and accessories for your rebreather.

Tech Tip: Etiquette and Rebreather Divers

Soon you may find yourself on a boat with a rebreather diver; or perhaps you may even get assigned a rebreather diver as a buddy. Like you, the rebreather diver has been trained to do a few minutes of setup and checks on their equipment before they dive. Often, another diver will approach and begin asking questions at just this moment. The rebreather diver really would like to talk about their equipment and answer questions, but part of their training included a reminder to avoid becoming distracted during their checks. Help them out by waiting until you see their setup is completed. If you are assigned a rebreather diver as a buddy, they will need to have a brief safety protocol discussion with you as there are some differences from your open-circuit training.



16lb Reef

Wall Dive Wall Dive | Boat access Boat access

Inside Port Phillip Marine Park - No Fishing Open Water Rated Reef Dive Site Slack Water

Depth: 12 m (39 ft) to 18 m (59 ft)

Level: Open Water and beyond.

16lb Reef was supposedly home to one of the biggest crays ever seen around Port Phillip. Originally spotted by a cray diver who was unable to reach it, the cray remained the stuff of legend until its existence was confirmed several years later. As far as anyone knows it is still there.

16lb Reef is located on Lonsdale Wall, near the heads, inside Port Phillip. There are many overhangs and small dropoffs, with a wide variety of fish including the spectacular Southern Blue Devil.

The Rip & Tides Warning: Always keep an eye on sea conditions throughout any shore or boat dive within "The Rip" (aka "The Heads"). This is a dangerous stretch of water, where Bass Straight meets Port Phillip, which has claimed many ships and lives. Please read the warnings on the web page diving-the-rip before diving or snorkelling this site.

Lonsdale Wall

This dive site is one of many on Lonsdale Wall, located just inside The Heads on the Lonsdale side of Port Philip — one of Australia's premier dive locations. Lonsdale Wall is one side of an underwater canyon formed by the old Yarra River as it flowed out to sea through the plains, carving steep-walled edges out of soft rock sides. Between the end of the last Ice Age around 8000 BCE and around 6000 BCE, the sea-level rose to drown what was then the lower reaches of the Yarra River. Thus the canyon formed by the river near what is now The Heads, or The Rip, was flooded creating the Lonsdale Wall, North Wall and Nepean Wall areas. Lonsdale Wall extends for one kilometre, providing many spectacular dive sites. An almost vertical drop characterises Lonsdale Wall with the wall starting as shallow as 8 m (26 ft) metres deep in places and sometimes dropping down to well over 60 m (197 ft) deep.

Port Phillip Heads Marine National Park

This site lies in the Port Phillip Heads Marine National Park. The park is made up of six separate marine areas around the southern end of Port Phillip: Swan Bay, Mud Islands, Point Lonsdale, Point Nepean, Popes Eye, and Portsea Hole.

Thirty-one of the 120 shipwrecks known to have occurred within a 10 nautical mile radius of Port Phillip Heads are thought to be within the Port Phillip Heads Marine National Park in Point Lonsdale and Point Nepean.

Aboriginal tradition indicates that the Bellarine Peninsula side of the Port Phillip Heads Marine National Park is part of Country of the Wathaurung people, and the Mornington Peninsula side, including Mud Islands, is part of Country of the Boon Wurrung people.

Traditional Owners — This dive site is in the traditional Country of the Wathaurong (Wadda-Warrung) people of the Kulin Nation. This truly ancient Country includes the coastline of Port Phillip, from the Werribee River in the north-east, the Bellarine Peninsula, and down to Cape Otway in the south-west. We wish to acknowledge the Wathaurong as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging. We acknowledge Bunjil the Creator Spirit of this beautiful land, who travels as an eagle, and Waarn, who protects the waterways and travels as a crow, and thank them for continuing to watch over this Country today and beyond.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
