Scuba diving regulators are what make diving possible. Forget every other piece of equipment; if you have a reg and an air source, you can dive. When Jacques Yves Cousteau and Emile Gagnan modified a welding regulator into a pressure-sensitive demand regulator in 1943, they opened the mysteries of the underwater world to anyone willing to discover them. In 1952, Melbourne based Ted Eldred invented the Porpoise separate first and second stage regulator that is the basis of today's modern regulator designs.

The Scuba Doctor has a wide range of regulators from carefully selected brands who all produce supreme performers in their own field of diving regulator design. These top-quality breathing regulators offer you enough choice to find the perfect regulator for your needs.

All of the scuba diving regulators we sell are CE EN250 certified. That is, they pass the requirements of the European standard for diving equipment to meet the demands placed on it at depth and under high breathing loads. This basically means that these regulators have been tested to make sure they will deliver gas to you at a depth of 50 metres, at acceptable temperatures, in any situation, even if you have two panicking divers demanding gas from them.

We're here to help you select the right scuba diving regulator, octopus and regulator accessories for your diving needs.

Types of Scuba Diving Regulators

Although there are many different brands and models of diving regulators to choose from there are only 3 basic types.

  • Balanced
  • Unbalanced
  • Over Balanced

Each of these types has its own characteristics, benefits and drawbacks.

Regulator Features

Diving regulators have a host of features, all of which you need to consider before spending your hard-earned cash. From how your regs attach to your air tank, to what you should look for in a second stage, everything from top to bottom needs to be looked at closely.

Maintenance and Care

An important consideration most people overlook is maintenance. If you buy an older model second-hand regulator or some exotic piece of equipment, you may have a hard time getting it serviced.

Scuba regulators should be serviced annually and if your local shop can't do it, you may have just bought yourself an expensive paperweight.

You also have to think about what if you have a problem on vacation? Will you be able to get your diving regulator serviced on-site?

If you stick with a fairly new regulator, of common make and model, you shouldn't have any trouble with service, home or abroad.

Putting It All Together

Before you buy your first set of scuba regulators you have some thinking to do. Not about the nice shiny new toy you are going to buy, but about what kind of diving you do and what kind of diver you are.

If you dive mostly on vacation, in warm tropical waters, on shallow coral reefs, you will require a far less robust, and expensive, diving regulator than if you are plunging to the cold depths on mixed gas.

Be honest with yourself.

Make a checklist of what you are looking for in a scuba diving regulator.

Start reading reviews and manufacturers specifications. Or call or email us. We're here to help.

Do your homework and you'll have scuba regulators that you'll enjoy and be able to dive with for years.

Tech Tip: Hose Protectors Don't Protect Hoses

The 'hose protectors' on the ends of the hoses next to the first stage provide a cosmetic appearance, however, there is no evidence they prevent hose damage. Hoses sometimes fail where the fitting is swaged onto the hose, but that's caused by gas pressure, and a hose protector is not going to prevent that from happening. Because hose protectors interfere with routing and streamlining, they are almost never seen on regs used in technical diving. In fact, hose protectors may compromise safety and many experienced divers don't use or recommend them. Hose protectors hold water against the fitting, causing corrosion and hiding developing problems. The post-dive maintenance recommendation is to pull the hose protectors back from the fittings, rinse and inspect. However, our observation is that not only do most divers not perform this suggested maintenance, when they do they are actually pulling hard at the most failure-prone part of the hose. Our maintenance recommendation: permanently remove all hose protectors (we carefully use a pair of side cutters rather than pull them off) and replace the hose if there is evidence of excessive wear or damage.

Open Water Rated Phillip Island Wreck Dive Site

Twin Screw Steam Bucket Dredge | Max Depth: 20 m (66 ft)

Level: Open Water and beyond.

The George Kermode is a scuttled steam bucket dredge boat sitting offshore from the Phillip Island Grand Prix Circuit on the southern side of Phillip Island. A fantastic wreck dive, she is fairly well intact with lots of penetration opportunities.

Given the location of the George Kermode off Phillip Island in Bass Strait, and the long run from launching at the Newhaven boat ramp or Flinders Pier, it usually requires a few days of strong northerly winds to flatten the swell out at the dive site.

The George Kermode shipwreck lies roughly 1.4 km SSE from the centre of Cunningham Bay (Siberia Corner of Phillip Island Circuit) upside-down in 20 m (66 ft) of water, coming up off the bottom to nearly 12 m (39 ft) in some places. It's a relatively shallow dive compared to most of the other wrecks accessible outside of Port Phillip so you get plenty of time to explore.

There are plenty of fish as well as interesting bits of industrial hardware like the enormous cog gear wheels. The George Kermode wreck is broken up in the middle, with big dredge buckets lying out on the sand in several locations. With the bottom of the hull pointing towards the sky, there is plenty to enjoy as you swim through the boilers. There are lots of nooks and crannies to look in, and it can be tricky to work out which bit of the wreck is which. For those suitably qualified, the George Kermode offers some excellent penetration. Accessible points of interest include two massive boilers, the chain lockers, and a large section of the bow.

The reef around the wreck site can also be an interesting dive.

See WillyWeather (Cunningham Bay) as a guide for the tide times and the height of the tide.

George Kermode Shipwreck History — Built in 1914

George Kermode Scuttling
George Kermode Scuttling
© Unknown

Built in 1914 by Fleming and Ferguson in Paisley, Scotland as Sir William Matthews for the Ceylon Government, she was a twin screwed steam bucket dredge. The overall length of the vessel was approximately 230.104 ft (70 m), beam 44.10 ft (13 m) and draught 17.10 ft (5.21 m) giving a displacement weight of 803 t (885 s-ton).

She was purchased from the Western Australian Government by the Melbourne Harbour Trust on 10 October 1941. After an extensive overhaul, the vessel was renamed the George Kermode and commenced operation in Victorian waters on 22 June 1942. The vessel was hired out to the Port of Burnie in 1945-46 but continued in the ownership of the Melbourne Harbour Trust.

George Kermode Sinking — Scuttled 1 April 1976

The George Kermode was scuttled by the Department of Conservation, Forests and Land on Thursday 1 April 1976 as part of an artificial reef programme. This program resulted in a number of artificial reefs being established in Port Phillip, including one off Carrum containing the wooden steamer Uralba.

Over the years we've been provided with different GPS marks for the George Kermode shipwreck. The GPS marks we know of in circulation for the George Kermode are:

  • Scuba Doctor:
    Latitude: 38° 31.230′ S   (38.5205° S / 38° 31′ 13.8″ S)
    Longitude: 145° 14.687′ E   (145.244783° E / 145° 14′ 41.22″ E)
  • Peter:
    Latitude: 38° 31.212′ S   (38.5202° S / 38° 31′ 12.72″ S)
    Longitude: 145° 14.712′ E   (145.2452° E / 145° 14′ 42.72″ E)

    49 m, bearing 47°, NE

The GPS mark we're using seems to be on the southern side of the wreck and near its western end. It might be a good place to anchor close by the wreck.

The GPS mark from "Peter" is pretty much amidships over the highest point of the shipwreck. It might be a good "first finder" mark but not so good to drop the pick on in case it falls inside.

The wreck alignment is about 60° (ENE), or 240° (WSW) going the other way. This may be of assistance to any first timers heading down to dive the George Kermode. You can launch your dive boat both from Flinders and from Newhaven (Phillip Island) boat ramps. The distances are similar at around 22 km one-way, but the more weather exposed route from Flinders requires careful consideration if there is any chance of a west or south-westerly springing up for the homeward run.

Heritage Warning: Any shipwreck or shipwreck relic that is 75 years or older is protected by legislation. Other items of maritime heritage 75 years or older are also protected by legislation. Activities such as digging for bottles, coins or other artefacts that involve the disturbance of archaeological sites may be in breach of the legislation, and penalties may apply. The legislation requires the mandatory reporting to Heritage Victoria as soon as practicable of any archaeological site that is identified. See Maritime heritage. Anyone with information about looting or stolen artefacts should call Heritage Victoria on (03) 7022 6390, or send an email to

Bass Strait Warning: Always keep an eye on sea conditions throughout any shore or boat dive in Bass Strait on Victoria's coastline. Please read the warnings on the web page diving-in-bass-strait 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.
