Tech Tip: Get the Lead Out!

Adding weight is rarely the solution to a trim problem. In many cases, just removing excess weight from the waist belt will reduce the size of the compensating gas bubble and is often a better approach to adjusting trim. However, sometimes the amount of weight is correct but it needs to be redistributed to correct a trim problem, particularly if aluminium cylinders or drysuits are involved. Proceed cautiously and try to remove weight somewhere else when adding a trim weight because in many cases the diver already has too much weight and adding weight, even trim weight, just makes the problem worse. For help as to how to figure out how much lead you need, please see The Scuba Doctor's Perfect Scuba Diving Weighting guide.

65 Metre Hole

Other | Boat access

Depth: 60 m (197 ft) to 65 m (213 ft)

The 65 Metre Hole dive site is inside Port Phillip. It's a slack water flood or ebb dive. It's a deep dive for technical rated divers.

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.

Wathaurong (Wadda-Warrung) country

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.
