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.

Depth: 2 m (6.56 ft) to 10 m (33 ft)

Level: Open Water and beyond.

Grant Bay Beach (aka Quarry Gates) lies at the western end of Grant Bay, about eight kilometres south of Portland, on Victoria's Discovery Coast. The beach is south of the Portland aluminium smelter, just east of the gates on Quarry Road to the Portland Harbour Trust Quarry.

Grant Bay, also known as Crayfish Bay, is located between Point Danger to the east and Cape Sir William Grant to the west. Grant Bay Beach is accessible from Quarry Road, Portland. A car park is located above Grant Bay Beach at the southern end of the public access on Quarry Road. The beach, which lies deep inside the open bay, faces south-east and is 150 metres long. It consists of a cobble and boulder beach, fronted by rocks and a sandy surf zone. The beach is partially protected by the cape and receives waves averaging between 1 and 1.5 metres. These break over the 100 metre wide sand bar and surge heavily up the steep, rocky beach face. There are two permanent rips draining the beach against the rocks at each end.

Diving and Snorkelling at Grant Bay Beach

There are permanent gutters against the rocks at each end of Grant Bay Beach, and deep water off the beach at high tide. Owing to the steep cobble and boulder beach and the presence of the rocks, reefs and permanent rips it's not a site frequently visited.

The most interesting dive is to head south following the eastern side of Cape Sir William Grant.

Location: Quarry Road, Portland, Victoria 3305

Parking: There is a car park above Grant Bay Beach at the southern end of the public access on Quarry Road, Portland. Before gearing up check out the water. If you see lots of white water, head on home.

Entry/exit: From the car park, head down to the beach and ente the water. Due to the nature of the beach, some prefer to dive the Grant Bay and Beach area as a boat dive.

Ideal Conditions: Grant Bay Beach faces east. It is protected from offshore south-westerly to north-easterly winds. Moderate to strong easterly to southerly winds are not favourable at this location. Best dived on a low swell.

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

Grant Bay Beach can also be accessed by boat from the Portland Harbour, Lee Breakwater Road North Ramp or the Portland Harbour, Lee Breakwater Road South Ramp.

Gunditjmara country
Gunditjmara country

Traditional Owners — This dive site is in the traditional Country of the Gunditjmara people of far south-western Victoria which continues over the state border into a small part of south-east South Australia and is bordered by the Glenelg River to the west and the Wannon River in the north. This truly ancient Country extends 100 metres out to sea from low tide and also includes Deen Maar (aka Lady Julia Percy Island) where the Gunditjmara believe the spirits of their dead travel to wait to be reborn. We wish to acknowledge the Gunditjmara as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging.

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.
