BCDs BCs


Buoyancy Control Device (BCD) for Scuba Divers: If you don't have the right one you can spend your dives constantly fighting your BCD. You want to float and it's dragging you down, you want to dive and it's keeping you up. For the most part, this is fixed by actually knowing how to use your BCD properly. But choosing the right BCD for your diving, needs and diving ability, make learning how to use it a lot easier.

Types of Scuba Diving BCD

There five basic types of Scuba Buoyancy Compensators.

  • Vest or Jacket
  • Rear or Back
  • Wing
  • Sidemount
  • Horse Collar

Only the first four of these are really used in scuba diving today.

We prefer back/rear inflation and wing style BCDs. Experienced divers have learned the rear inflation bladder BCDs are better than a wrap-around bladder jacket/vest BCDs. Rear wings offer very precise control of buoyancy and trim as well as offering a more streamlined profile. A properly fitting back/rear inflation BCD, worn with a crotch strap, will allow you to assume and hold any position under the water, or on the surface.

BCD Features

Buoyancy compensators can have a ton of features, or very few. Options are almost limitless.

The more features it has usually the more expensive it is. But what do you need, and what is just fluff is what you have to think about.

Maintenance And Care

Scuba BCDs are expensive. Practicing good post-dive care and general maintenance will give your equipment a long life and save you from having to spend money on a new one.

Putting It All Together

There is a lot to consider before buying a BCD.

On the surface a scuba BCD should fit like a snug jacket. Not too tight under the arms, or across the torso. Women should choose a model designed for them.

But like everything else when it comes to diving, it's about more than just fit and style

You need to consider what type of diving you are doing, and what gear you'll need to carry with you to do it. A BCD is not just an airbag. A good one is like Batman's utility belt.

Consider what features are essential to you, and find the one that most closely fits that profile.

Start reading reviews and manufacturers materials, read forums and ask other divers for their opinions. Or just call and ask us.

Be honest with yourself about the type of diving you'll be doing. Make a checklist of everything you need in a scuba BCD,do your homework, and you should end up with the right scuba BCD for you.

Seal Gully

Reef Dive Reef Dive | Boat access Boat access

Marine Park - No Fishing Open Water Rated Reef Dive Site

Depth: 1 m (3.28 ft) to 8 m (26 ft)

Level: Open Water and beyond.

Seal Gully is aptly named after the Australian Fur Seals that often camp at this spot when not hauled out on the drying section of Beware Reef. This site lies immediately to the south-east of the drying reef.

It is a large crack in the rock about 6 metres deep that runs to the south for over 50 metres before broadening out into deeper water at its southern end. This is a beautiful dive for small groups as the space on hand does not allow for much manoeuvring by the diver.

The top lip of the gully is covered in cray weed and bull kelp so it is better to dive within the confines of the gully where the real action is. The two walls of the gully are teeming with invertebrate life: Jewell anemones, zoanthids, soft and hard corals, hydroids, bryzoan, sponges, and nudibranchs to name but a few.

The younger seals will always be inquisitive and will often come and take a look to check you out, so be ready with the camera for that special shot. Even though this is one of the shallowest dives, this site can be prone to extreme currents and heavy surges, so both divers and skippers of boats be aware of the conditions before entering the water. Seals are protected by law.

Beware Reef Marine Sanctuary

This dive site lies in the Beware Reef Marine Sanctuary which is a challenging place to dive, please take care.

Beware Reef Marine Sanctuary encompasses a series of pinnacles of granite rock rising 30 metres off the sea floor, with only a small section at its northern extremity rising some two metres above sea level. This underwater mountain range runs for just over one kilometre to the south-east from the drying part of the reef, and the marine sanctuary that protects this unique reef covers an area of 220 hectares. The reef lies five kilometres to the south-east of Cape Conran and about three kilometres offshore from the beach at Yeerung River.

Dive Sites

Dive sites at Beware Reef Marine Sanctuary include:

There are many other great sites for the inquisitive diver to explore here.

Boat Launch

There is a boat ramp at West Cape, Cape Conran which is suitable for most vessels up to six metres and a 4WD is normally required for launch and retrieval. The ramp can be inundated with sand and kelp for short periods of time. Due to the shallow angle of the ramp, low tides can be difficult to launch and retrieve vessels.

The boat launch site is exposed to westerly/ south-westerly winds and ocean swells. Calm sea conditions with light northerly winds and higher tides is ideal.

From the boat ramp at West Cape, avoid 'prop rock' which is about 50 metres directly out from the ramp and very shallow at low tide, and head south until you round the cape. Once clear of the cape head in an easterly direction for about 4 kilometres. The exposed section of Beware Reef is visible on a clear day once you clear the tip of Cape Conran. Often whitewater can be seen breaking on the exposed reef before the bare rock itself is sighted.

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.
