Hookah Regulators


Hookah rigs deliver air from a compressor on the surface down to a diver below, just like those old school cartoons. Divers doing serious long term jobs underwater may opt for these regulators, which are specially designed for hookah style diving. Please bear in mind that a regular scuba diving regulator cannot be used for hookah applications! Hookah regulators function with a different set of pressures and have specific regulators for specific conditions.

A Hookah regulator setup is entirely different from a scuba regulator. It consists of a 'second stage' only, which is fed directly from the output of the reserve tank via a Hookah air hose. There are no tank valve and first stage regulator assemblies of the type that are used with scuba cylinders.

Hookah second stage regulators typically employ a 'tilt', or 'pin' valve, which delivers a full airflow to the diver at low-pressure. This type of regulator is specifically designed for use with low-pressure Hookah compressors. Hookah second stage regulators, as are all modern regulators, are of the single hose, 'demand' type. A 'demand' regulator works on a relatively low volume of air since it only has to deliver air as the diver breathes, or 'demands' it.

Scuba second stage regulators typically can't be used for Hookah applications without special modifications. A typical Hookah compressor operates in a low-pressure range which is not enough pressure to drive the spring-loaded downstream valve of a scuba second stage regulator.

A diver who already owns a scuba second stage regulator, but who wishes to use it for Hookah applications, must take the regulator to a competent dive shop and get the regulator converted over for low-pressure use. The conversion can be made by installing a set of low tension springs which will give maximum efficiency when operated at low Hookah pressures. A dive shop will also have the necessary test equipment to make certain the adaptation has been effective.

Please read Introduction to Hookah Diving for more information about things you need to consider with a hookah diving setup.

Depth: 8 m (26 ft) to 20 m (66 ft)

Level: Open Water and beyond.

McKechnie Craig Bommie includes 100 ha of reef area between Boulder Point (aka Bluenose) and House Reef (a large reef platform with the solitary house on the cliff above) on Victoria's Discovery Coast. When locals think of The Crags, they usually have in mind McKechnie Craig Bommie rather than the "car park" Crags (which are found a further 3 km to the north-west).

At Cape Reamur, the coast swings to the north-west and begins the 50 km long, sweeping arc that becomes Portland Bay.

McKechnies Craigs Bommie sits in the southern portion and rises to within a few metres of the surface. The entire south-west edge of the reef complex is bounded by a sand edge ranging from 8 metres at the northern end to 20 metres south of the bommie.

The extent and variety of diving here has to be seen to be believed. Bare tumbled boulders along the deeper sand edge, through to thick stands of kelp and cray weed. The location has been a huge contributor to the commercial abalone catch for many decades.

McKechnie Craig Bommie is reached by boat heading out from the Port Fairy, Griffiths Street Boat Ramp.

McKechnie Craig Bommie is exposed to the westerly winds and waves. Best dived with a low swell. See WillyWeather (Cape Reamur) as a guide for the tide times and the height of the tide.

Eastern Maar country
Eastern Maar country

Traditional Owners — This dive site is in the traditional Country of the Eastern Maar people of south-western Victoria between the Shaw and Eumerella Rivers and from Yambuk in the south to beyond Lake Linlithgow in the north. This truly ancient Country extends as far north as Ararat and encompasses the coastal townships of Port Fairy in the west, Warrnambool, Peterborough, Port Campbell, Apollo Bay, Lorne, and Airies Inlet in the east, including the Great Ocean Road area. It also stretches 100 metres out to sea from low tide and therefore includes the iconic Twelve Apostles. "Eastern Maar" is a name adopted by the people who identify as Maar, Eastern Gunditjmara, Tjap Wurrung, Peek Whurrong, Kirrae Whurrung, Kuurn Kopan Noot and/or Yarro waetch (Tooram Tribe) amongst others. We wish to acknowledge the Eastern Maar as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging.

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.
