BC/BCD Wings


Confused by the different brands?
All of the modular backplate and wing systems we sell are modular, and will work when mixing between component brands. Just because you have a particular brand of backplate doesn't mean you need to buy the same manufacture harness and wing. Different manufacturers each have their own features and selling points, and like everything there are pros and cons which matter differently to different divers.

Tech Tip:
Will back inflation float an unconscious diver face up?

We usually hear this from divers who have always worn a jacket style BC, and we'd like to point out that it's irrelevant. It's true, that boating regulations require an approved wearable Personal Floatation Device (PFD) to float the unconscious victim face up in the water. But a Buoyancy Control Device (BCD) for scuba divers is not designed to be a PFD for an unconscious boating accident victim, regardless if the BC is jacket or back inflation.

We offer back inflation style options because experienced divers have learned the back inflation BCD is better than a jacket BCD, offering very precise control of buoyancy and trim as well as offering a more streamlined profile. An improperly fitted back inflation BCD might cause you to tip forward, but a properly fitted back inflation BCD, worn with a crotch strap, will allow you to assume and hold any position under the water, or on the surface.

When on the surface, divers new to back inflation will need to break the habit of holding down the power inflator until they feel squeeze (there won't be any), or hear the OPV release. With an over inflated air cell they will have a huge amount of buoyancy on their back, causing them to float too high in the water and tip forward. Instead, they should add only enough gas until their head is just above the water.

Finally, a very common error when selecting a back inflation BCD is to choose an buoyancy aircell (called a 'wing') that is much too big, causing a 'taco effect' that makes managing buoyancy considerably more difficult. The cylinder size, type and configuration, not lift capacity, is the best guide to selecting the correct wing. While many doubles wing designs can be adjusted for occasional use with singles, keep in mind they are not designed to be used primarily as singles wings and they are not optimal with singles. Unless you are diving one of the very large steel cylinders, a 30 lb (14 kg) is about the maximum lift you need for single tank sport diving.

Depth: 2 m (6.56 ft) to 12 m (39 ft)

Kitty Miller Bay lies on the south coast of Phillip Island, between Watt Point to the east and Kennan Head to the west, looking out into Bass Strait. This secretive splash spot is directly adjacent to the world-famous Phillip Island Penguin Parade. Kitty Miller Bay is one of Phillip Island's best protected beaches. Great for snorkelling and scuba diving.

The western side of the bay is more protected, but the eastern side is more interesting if you're experienced enough to handle the sometime challenging conditions.

At the southern end of Kitty Miller Road, Phillip Island, it's a long walk from the car park down to the rocky beach of Kitty Miller Bay. There are entry points to the western and eastern side of the bay.

Kitty Miller Bay features 500 metres of shoreline shelter, vast rock platforms, seaweed gardens and seagrass beds, bustling with zebra fish, leather jackets, rays and Port Jackson sharks. Inexperienced snorkellers should stick to the shallows of the western corner, while those with more confidence might try the east. Take care at all times: the water might appear calm, but conditions can change quickly.

Ideal Conditions: Kitty Miller Bay is one of the safer south coast beaches, owing to the generally low waves and gently sloping central beach section. The best conditions come after several days of still weather or northerly winds. Enter on the receding tide, whenever it is safe to do so. The lower the tide, the more protected the waters, but some areas are better at mid-tide. See WillyWeather (Kitty Miller Bay) as a guide for the tide times and the height of the tide.

Kitty Miller Bay lies 500 metres inside the bordering Watt Point and Kennon Head, with wide rock platforms at the base of the headlands, and reefs in between them. Consequently, the 500 metre long, semi-circular, south facing beach is reasonably sheltered and waves average only 0.7 metre at the beach, and even lower at low tide.

Kitty Miller Road runs straight out to the beach, with a small car park behind the low dune that backs the beach. The beach is narrow at high tide, while at low tide it expands to more than 50 metres wide, with deeper water off the centre and extensive intertidal rock flats to either side. Rips are only present during higher waves.

Kitty Miller Bay is named after the daughter of a Phillip Island settler (Phillip Island Historical Society).

Speke Shipwreck

The shipwreck of the Speke lies nearby on the eastern side of Watt Point. The 3000 ton, 100m long, steel barque was on a voyage from Melbourne to South America when she saw hit by a huge storm off Phillip Island. She was driven ashore in February 1906 and broke up on the sea terrace just to the east of Walt Point. The bow wreckage is visible at low water. The rest of the wreck lies in shallow water close to the sea terrace and has been pulverised into small pieces by the swell. The reefs in the surrounding area are also interesting.

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.
