LP 1st Stage Adaptors
The Scuba Doctor offers a large variety of low pressure (LP) first stage regulator port adaptors for recreational, technical, rebreather, sidemount and commercial diving applications.
Most low-pressure hoses are 3/8-inch male and most first stage low-pressure ports are 3/8-inch female. A few brands of first stages have a special low-pressure port that is 1/2-inch female, notably some Apex and older Aqualung models. We offer 1/2-inch to 3/8-inch adaptors.
Reminder: The actual configuration of an adaptor is a mirror image of its use. A 3/8"-24 UNF FEMALE port requires a 3/8"-24 UNF MALE adaptor etc. In technical diving operations where many fittings may get co-mingled, be sure that all adaptor combinations can accommodate the intended flows and pressures.
Looking for a particular fitting you don't see here? Let us know and we'll see if we can order it for you.
We reserve the right to limit order quantities to less than 10 pieces because our supply is appropriate for the demands of individual divers, but not bulk orders. Large volume bulk orders will NOT qualify for our free shipping promotion.
Toms Cave
Wall Dive | 
Boat access
Depth: 22 m (72 ft) to 30 m (98 ft)
Tom's Cave is a nice little cave dive on Lonsdale Wall. The entrance on the wall is at around 30 m (98 ft), then you proceed through the cave and exit at about 22 m (72 ft). It's an easy swim through for advanced divers. There is plenty to see in the area where you exit Tom's Cave.
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.

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.
