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.

The Cambridge (SS Cambridge) was a refrigerated steam cargo liner that was built in Germany and launched in 1916 as the Vogtland. Later renamed Cambridge, she operated between Britain and Australasia until 1940, when a German mine sank her off the coast of Wilsons Promontory.

The shipwreck of the SS Cambridge is historically significant as the first Allied vessel to be lost in Australian waters in World War II. Along with the wrecks of the MS City of Rayville (1940), HMAS Goorangai (1940) and SS Iron Crown (1942) the Cambridge represents the arrival of World War II in Australian waters, the strategic importance of the Bass Strait shipping lane, and the extent of Axis activities in the Southern hemisphere.

Diving the Cambridge Shipwreck

The Cambridge was located on 21 May 1988 by the National Safety Council vessel M.V. Blue Nabila using side scan sonar. The vessel is relatively intact and lies in 68 metres of water. The GPS mark we have for the Cambridge is near the stern.

Cambridge Shipwreck History — Built in 1916

The Cambridge was a steel twin screw steamer built in 1916, by J. C. Tecklenborg AG in Wesermunde, Germany. She was built as a refrigerated steam cargo liner on a length of 524.5 ft (160 m), a breadth of 65.7 ft (20 m) and a draught of 37.3 ft (11 m). As built, her tonnages were Units: unknown unit type given, Units: unknown unit type given and Units: unknown unit type given. Her holds had Units: unknown unit type given of refrigerated cargo space.

The vessel had two screws, each driven by a triple expansion engine. Between them her twin engines were rated at 1,106 nominal horsepower (nhp) or 3,475 indicated horsepower (ihp), giving her a speed of 14 knots (26 kpm). The ship had one funnel and four masts.

The steamer was originally built as the Vogtland, but after World War 1, the vessel was taken as part war reparations and its name changed to Cambridge.

Cambridge Sinking — Wrecked 7 November 1940

While on a voyage from Cardiff (United Kingdom) to Brisbane via Sydney, with tin plate and a general cargo, with a crew of 58 under the command of Captain A. J. Paddy Agnell, the SS Cambridge struck a German mine and sunk in Bass Strait, 3.7 nm (6.85 km) SE of Wilsons Promontory.

At about 11 p.m. on Thursday 7 November 1940 as the Cambridge headed east past Wilsons Promontory, a sudden explosion occurred and the vessel started to sink by the stern. The explosion occurred in the after end of the ship. An attempt to send out a distress signal on the wireless failed because the dynamos had been damaged in the explosion. The emergency wireless set was used to send distress signals. As the ship was settling quickly the crew were mustered and ordered to abandon ship, and three lifeboats were launched.

The lifeboats with the crew aboard quickly cleared the sinking vessel. However, the ship's carpenter, J. Kinnear, was observed on the deck of the Cambridge. Because of the danger of being submerged by the suction of the fast sinking vessel, the lifeboats were unable to get close enough to save him. It was believed that he went below to retrieve personal items when the rest of the crew were abandoning ship.

Captain Angell later described the Cambridge as it "sank under the waves and disappeared leaving only a great spout of water and steam rising into the sky, then settling down into a bubbling patch of sea".

The gear from the lifeboats was salved but the boats themselves were abandoned because the sea was too rough to take them in tow. The crew then spent an anxious night floating around in a minefield. They knew land was not far away as they could see the South-East Point lighthouse, but were additionally worried about drifting further out to sea. However they were picked up in the morning by the minesweeper HMAS Orara, and taken ashore at Port Welshpool.

Bass Strait was closed to shipping and the HMAS Orara and another minesweeper the HMAS Durraween commenced sweeping off the Promontory on 9 November 1940, and eventually 43 mines from the Bass Strait fields were detonated or rendered safe after being washed ashore.

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.
