Aqualung Dimension BCD Black/Charcoal
Regular price $699.00Unit price
Product Information
This is a used Aqua Lung Dimension BCD, a back-inflation buoyancy compensator designed to hold a stable horizontal trim while keeping the chest and torso clear of bulk. Lift sits behind the diver and the bladder wraps around the cylinder, keeping the front of the harness open for gauges and accessories.
An adjustable harness accommodates a range of torso lengths, and the integrated weight system releases with a single pull. Durable fabric panels and reinforced stitching stand up to repeated saltwater exposure.
As a used item, this BCD shows cosmetic wear consistent with prior diving. Please review the listing photos for the condition of this specific unit.
- Wrapture Harness System: patented swivel shoulder buckles and ultra-thin back plate provide unsurpassed comfort and prevent the BCD from riding up on the surface. Out of the water, the system allows you to stand up straight by keeping the cylinder close to your center of gravity and transferring the weight to your hips
- SureLock II Weight Release: Safe, single-pull weight release with patented SureLock II Mechanical Weight Release System
- ResisteK Material: Looks good, and stays that way, made of new, technologically advanced ResisteK material to resist fading and abrasion in saltwater and chlorine
- HP Hose Routings: HP hose routings through the back keep your entire kit low profile, minimizing drag
- Smooth, Flat Valves: Proprietary flat valves further reduce drag
- Bladder Retraction System: Bladder retraction system pulls in the sides of the bladder during deflation to keep you streamlined and reduce drag
- Adjustable Chest Strap: Adjustable sliding chest strap can be raised or lowered on a rail system for added comfort. Helps you avoid drysuit valves
- Additional Dump Option: Right shoulder pull
- Gear Up!: Multiple pockets, D-rings, and knife attachment points make stowing and accessing gear easy
- Rolled Neck Collar: Comfortable rolled neck collar
- Non-Ditchable Weight Pockets: Located on the back of the BCD, these pockets help you achieve proper positioning in the water
- Capacity: All sizes of the Dimension are capable of holding up to 30lbs/13.5kg of lead weight

Frequently Asked Questions
How should a scuba BCD fit?
A BCD should fit snugly enough that it does not ride up toward your ears when inflated, while still letting you breathe fully. Fasten the waist and cummerbund first, then adjust the shoulder straps so the tank sits close to your back and the shoulders cannot slide off. With the BCD fully inflated at the surface you should still be able to take a deep, comfortable breath; if it squeezes your chest, loosen it or move up a size.
How do I rinse and care for a BCD after diving?
Rinse the outside in fresh water and also flush the inside of the bladder, because salt water gets in through the inflator and dump valves. Fill the bladder roughly a third full of fresh water through the oral inflator, slosh it around, then drain it out through the inflator and each dump valve. Hang it to dry out of direct sunlight and store it partially inflated so the bladder walls do not stick together.
Should I use integrated weights or a weight belt?
Integrated weight pockets carry the lead in the BCD itself, which many divers find more comfortable and easier on the hips, while a weight belt keeps the weight independent of your BCD. Either way, you must be able to release your ditchable weight quickly with one hand, and your buddy should know how your system releases. Non-ditchable trim pockets are useful for balance but should never hold weight you might need to drop.
How do I pack a BCD for travel?
Make sure the BCD is completely dry inside and out before packing so it does not mildew in transit. Remove all weights, deflate it fully, and fold or roll it around softer items such as a wetsuit to cushion the inflator and valves. Avoid hard creases in the air cell, and unpack and air it out as soon as you arrive.
When does a BCD need to be serviced?
Follow the service interval in the manufacturer's manual, which is commonly an annual inspection alongside the rest of your life-support gear. Have the inflator, dump valves, and bladder checked any time the inflator sticks, free-flows, feels rough, or the BCD holds air poorly. Between services, confirm that it inflates and deflates properly as part of every pre-dive check.
What is the difference between a jacket-style and a back-inflate BCD?
A jacket-style BCD holds air in panels that wrap around your sides as well as your back, while a back-inflate BCD keeps the entire air cell behind you. Jacket styles tend to feel very stable and upright at the surface, and back-inflate styles keep the chest clear and are often preferred for horizontal trim underwater. Neither is objectively better, so treat it as a fit and preference decision and try both if you can.
Will my BCD fit any scuba tank?
Most recreational BCDs use an adjustable cam band sized for common single-cylinder diameters, so standard aluminum and steel tanks generally work. Re-check the band tension after the first wetting, because webbing can relax slightly and let the tank shift. If you dive doubles or unusual cylinder diameters, confirm compatibility with the manufacturer before assuming it will hold.
