Cylinder Stickers
Tank marking stickers and decals from The Scuba Doctor are the perfect way to correctly and safely label the contents of a cylinder.
Tech Tip: Do I really need that big Nitrox wrap decal on my cylinder?
The large Nitrox tank wrap requirement mostly depends on your local dive shop fill policy. When Nitrox was introduced to sport diving there was widespread anxiety at local dive shop fill stations about cylinder contamination and handling safety. There were also fears of an injury as the result of an unqualified diver inadvertently breathing Voodoo Gas. While there is no law that requires the Nitrox wrap, the highly visible 'Nitrox', 'Nitrox Only', or 'Enriched Air Nitrox' tank wrap was helpful in addressing those early concerns.
Today, experience has demonstrated those safety worries about Nitrox to be relatively minor issues for the sport diving community. The large Nitrox tank wrap was quickly proven to be an imperfect solution to ensuring handling safety and identifying cylinder contents.
Many fill stations have adopted policies and practices that do not rely upon the presence of the Nitrox wrap. As a result, some local dive shops have become ambivalent about requiring the large wraps and are satisfied with a small removable tape label or tag that indicates cylinder contents analysis.
The factor that often determines the large permanent wrap requirement at many local dive shops is how the shop handles Nitrox fills. Shops that fill using premixed gas tend not to require the large wraps, but shops that partial pressure blend in the cylinder itself may still require the wraps.
In the early days practically all Nitrox fills were done using partial pressure blending, causing a common misconception that presence of a Nitrox tank wrap indicates the cylinder and valve are oxygen clean and oxygen compatible. However, the Nitrox wrap does NOT indicate the oxygen cleanliness or oxygen compatibility of the cylinder and valve, the wrap is just a label of what type of gas blend the cylinder may contain.
A separate evidence of inspection decal (aka VIP sticker) is what indicates if cylinder and valve are both suitable for use with compressed gases containing more than 23.5% oxygen at the date of inspection. Dive shop filling stations doing partial pressure blending will insist on your tank have an in-date Oxygen Clean sticker applied by the testing station that oxygen cleaned your cylinder.
Neither the Nitrox sticker or the Oxygen Clean decal indicate what compressed gas is stored in the cylinder. You should properly and clearly label your cylinder with your analysis of the gas mixture.
Clearly label anything that isn't air. If the MOD is less than the maximum possible depth of the dive (think deco cylinders), make sure the MOD stands out where not only you can see it, so can your buddies. Make it obvious to everyone if you are using the wrong cylinder at the wrong depth.
Consider putting a small piece of tape on each second stage, just in front of the mouthpiece, that has the MOD for the cylinder it is attached to. (This is in addition to the standard cylinder markings.) Any little thing that may save your life helps.
Tech Tip: Perfect Positioning of Scuba Tank Stickers
Select the general spot on your scuba cylinder to place the sticker and remove any old stickers and decals from that spot. On painted aluminium cylinders we recommend scraping any blistering or peeling areas to remove loose paint. Take an appropriate cleaner/solvent and wipe the area down a couple of times to remove dirt, wax and all other enemies of good adhesion. If you use any cleaning solvent, keep it off the valve and neck and be sure to rinse with soap and water when you are done.
Once the cylinder is clean, peel the backing off your sticker. Now the trick is to simply spray the area where the sticker is to be placed and also lightly wet the adhesive back of the sticker, with a thin coat of soapy water or Windex before you install the sticker. This gives a little lubrication and just enough surface tension to hold the sticker but not fully adhere it to the surface.
Apply the sticker to the cylinder. While wet, you can slip and slide the sticker into the perfect position. When you're sure it's in the right spot you simply hold it with one hand and squeegee the liquid out with the other.
Once it feels fairly adhered, blot the excess liquid off, and stand back to confirm placement. We say this because you still have some time to pull it off and re-position without penalty as there is a bit of liquid still under the sticker. Once the soap evaporates, the sticker adheres very well to the tank.

Level: Open Water and beyond.
The Gange was a nearly-new, three-masted iron barque on only its second voyage, that was wrecked when it ran aground on Saturday 23 July 1887 on Point Lonsdale Reef.
The Gange shipwreck is historically and socially significant for the interest its wrecking caused in the Victorian community, and the impact the event had on Victorian Pilots Service.
Diving the Gange Shipwreck
The wreck of the Gange lies to the west and seaward of Point Lonsdale Reef, near the Holyhead and George Roper.
The remains of the Gange today are easily recognisable, by the rails and barrels of ruin cement littering the bottom to the South of the outer reef at Point Lonsdale.
The hull of the Gange has broken into two main sections, and though it is quite broken up and flat and there are conspicuous white barrel shaped blocks and other fragments of concrete — remnants of the cargo — that identify the site as being that of the Gange. Some railway iron can also be seen near the site hard up against the reef which may have also been part of the cargo. Wreckage of the Black Boy is also said to be intermingled with that of the Gange and hard to tell apart.
The site is in an area of heavy surge. It is a highly oxygenated white water zone. There is strong surge on the site. As this site is tidal. it's best to dive between the end of the ebb and start of the flood tide.
See WillyWeather (Rip Bank) as a guide for the tide times and the height of the tide.
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.
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.
Gange Shipwreck History — Built in 1885
The Gange was a three-mastered iron barque of 1,071 tons, built in 1885, on the dimensions of 152 ft (46 m) in length, a breadth of 30.1 ft (9.17 m) and a depth of 16.8 ft (5.12 m), by N. Martinloch, Lussin Piccolo on the Gulf of Quarnero, Illyria. The owner of the vessel at the time of its sinking was Eredi Tarabochia of Austria.
Gange Sinking — Wrecked 23 July 1887
Wreck of Austrian Barque Gange

On Friday 22 July 1887, the Gange was nearing the completion of a voyage from London to Melbourne, under the command of Captain Ivaneich, with a crew of 17 (mainly Austrian, with one Greek and two Italians), plus one passenger, newly wed Captain Ivaneich's 18-year old wife, Mrs Nilla Ivaneich, on her honeymoon voyage.
After a voyage of 125 days, at night in squally south-westerly conditions accompanied by rain and hail and a strong ebb tide, the Gange was standing clear of The Heads waiting for a pilot and was burning rockets to attract attention. Captain Ivaneich did not understand a message from one pilot steamer and a boat launched by another failed to get a rope to the barque. The crew of the Gange, meanwhile, were having difficulties with the sails, an ongoing problem during the voyage ascribed by the Captain to the way the vessel had been loaded. As the vessel went to go about a strong squall hit and carried away the foresail sheet, lower topsail and the trysail, and a number of the crew were injured trying to control a vessel.
At this stage, around 9:00 p.m., the Gange was in an extremely perilous position and about to go ashore on Nepean Reef but, due to the risky efforts by the pilots on the schooner Mavis to get close to the barque and lead her westwards out of trouble, this was avoided.
Gradually, the Gange made its way out of danger to the relief of the pilots but unfortunately was now sailing at a rate of five to six knots in a direct line for Point Lonsdale, the Captain believing the blue light the Mavis was burning to lead the Gange out of trouble was to lead him through The Heads. At 11:00 p.m. the ship shook badly, an indication it had grounded. Immediately waves crashed over the decks, flooding the cabins, and Captain Ivaneich ordered the crew to prepare the boats for an opportunity to leave the ship. However, the seas were too heavy and their first priority was to survive by clinging to the rigging. They remained there until midnight, when the Queenscliff lifeboat which had remained anchored near the vessel all night was able to get alongside and rescue off the crew, the Captain and his wife on Saturday 23 July 1887.
Captain Ivaneich (the only person who could speak English among the crew) and the pilots gave conflicting views about the events of that night, the Captain saying he had signalled for a pilot and did not receive one and the pilots saying they were not able to get aboard the Gange as no rope was thrown to them.
However, at the Pilots Board Inquiry, the pilots were exonerated from blame. The press criticised the piloting procedures saying that, like the wreck of the Glaneuse, both large wrecks involved foreign ships and masters who both said they signalled for the assistance of a pilot but did not attain one. Part of the problem was that pilots did not venture for enough out beyond The Heads to meet the ships before they were close to the dangerous entrance.
The Gange was making only its second voyage, consigned to Messrs Robert Virgoe and Co. of Melbourne. The circumstances of loss similar to that of Glaneuse, and there was some comment in the media regarding foreign captains.
The ship broke up during a gale on 7 September 1887 — vessels warned to watch out for floating wreckage. The ship and cargo realised £165 at auction. Not in Lloyds. The wreck of the Gange lies close to the Holyhead and George Roper.

Port Phillip Heads Marine National Park
This site lies in the Port Phillip Heads Marine National Park. The park is made up of six separate marine areas around the southern end of Port Phillip: Swan Bay, Mud Islands, Point Lonsdale, Point Nepean, Popes Eye, and Portsea Hole.
Thirty-one of the 120 shipwrecks known to have occurred within a 10 nautical mile radius of Port Phillip Heads are thought to be within the Port Phillip Heads Marine National Park in Point Lonsdale and Point Nepean.
Aboriginal tradition indicates that the Bellarine Peninsula side of the Port Phillip Heads Marine National Park is part of Country of the Wathaurung people, and the Mornington Peninsula side, including Mud Islands, is part of Country of the Boon Wurrung people.

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.
