BCD (Buoyancy Control Device)
(BCD) Buoyancy Control Device comes in many shapes and sizes for both men and women, but its main purpose is to help you control your buoyancy underwater and to provide a safe resting float at the surface.
Buoyancy is controlled with an single air bladder which is either positioned in the rear of the BCD or distributed (jacket-style). Rear lift BCDs allow A little more freedom of movement While diving but are harder to balance at the surface. The tank is secured to the BCD’s backpack with a strap and buckle. Backpacks can differ in their rigidity, but the main difference between backpacks is in their padding.
Cold water diving calls for the use of thick wetsuits, both of which require ample lead to offset their buoyancy, and a BC with enough lift capacity to compensate for the loss of that buoyancy at depth. In contrast, warm water diving requires that a BC have little more than a place to strap the tank, hang your hoses and enough lift to float the diver and minimal weight.
Additional features:
Material weights from 400 to 1000 Denier Nylon. The higher the number means the more abrasion resistant.
BCs offer a variety of shoulder and waist adjustments to help you custom fit the BC to your body.
Single and Dual Tank band configurations.
Quick releases on the shoulders make for easy removal on the deck or in an emergency.
Weight integrated - conveniently and comfortably allows you to carry some of your lead in your BCD. One should still wear a standard weight belt as well with the integrated BC to lower the weight in the unit and to add better balance. This also reduces staff fatigue lifting and retrieving after dives.
A thoughtful diver will remove the weight pockets and hand them up to the boat rather than expecting staff to lift a heavy unit.
Clips & pockets - positioned to provide convenient access to lights, knives, writing tablets, etc

Aqua light BCD
New, highly improved version of the Aqua light model, this BC has been specifically designed for travelers and divers who want an ultra light BC without sacrificing that Cressi quality, finish and accessories. It is made from 210-denier nylon combined with a special self-draining webbing. The soft backpack and tank attachment includes non-slip cushioning and two cam bands. The new version also introduces two large zip-up pockets on this model, perfect to stow small and large accessories. Two wallet weight pockets are applied on the outer side of the main pockets, locked into position by a 40mm adjustable buckle. These pockets have been designed to stow a modest quantity of weight (up to a maximum of 3kg per pocket), which can be instantly dumped thanks to the “gravity” system.
Who it's for
Aqua light R is the perfect BC for demanding travelers. It is ultra light and strong at the same time and comes with all the accessories and technical features that have made Cressi Bcds famous worldwide. Because it is close-fitting it has highly streamlined buoyancy, excellent even in strong currents.
This new version of the Aqua light BC has some new, improved features, putting it right at the top of its category. Users love this BC because it is lightweight, easy to carry and it has excellent buoyancy, which in practice means excellent diving performance, even when dealing with currents. It is made from 210-denier nylon, as it is light and strong at the same time, combined with a special self-draining webbing and strong grip rubber material inserts. The BC structure does not have a rigid backpack to make for easy carrying. The tank is attached with special non-slip cushioning, complete with two cam bands. On the back, at the top of the BC, there is a carry handle that can also be used as an extra safety attachment for the tank valves. The back part of the BC inner is well-padded for diver comfort. The waist strap is separate from the bag and is topped with a dual adjustment strap, allowing a natural “fold out” opening of the BC when there is a large amount of air, so the diver never feels any compression or constricting sensation. It has three deflation/pressure valves: one on the upper end of the hose, a second one on the right shoulder, controlled by a pull tab and third one fitted to the bottom right rear, like all Cressi Bcds controlled by a pull tab with the control on the lower front side of the BC for easier and quicker access to the deflation knob. The two zip-up accessories pockets have been enlarged. They are topped by 2 wallet-style weight pockets, which have also been expanded and are locked into position by a 40mm adjustable buckle. These pockets have been designed to stow a modest quantity of weight, up to a maximum of 3kg per pocket; the weight can be easily stowed even in the water and instantly dumped thanks to the gravity system. Technical features - Two external webbed pockets, which can also be activated in the water - Two large, zip-up accessories pockets - Three deflation and pressure relief valves - Rear valve with front control - Soft, well-padded backpack - Padded cushioning and two cam bands to hold the tank - Two 50mm techno polymer D-rings on the shoulders - Two 50mm techno polymer D-rings on the bottom edge of the BC - Two 30mm techno polymer D-rings above the pockets - Adjustable waist strap - Ultra light and easy to carry - Material: 210 denier nylon and self-draining webbing - Sizes: XS, S, M, L, XL - Buoyancy in Newton: 75 (XS), 90 (S), 105 (M), 150 (L), 160(XL) - Buoyancy in kg: 7.7 (XS), 9.2 (S), 10.7 (M), 15.3 (L), 16.3 (XL) - Buoyancy in lbs: 16.9 (XS), 20.2 (S), 23.6 (M), 33.7 (L), 36.0 (XL) (values certified by R.I.N.A. according to CE standard 0474) - Weight in kg: 2.300 (XS), 2.350 (S), 2.550 (M), 2.650 (L), 2.750 (XL) AERO PRO 
Spearhead model of the new AERO range, it has been specifically designed to be able to stow all the diver's weights in the different pockets. Complete with the brand new Lock-Aid System (L.A.S.), which consists of two special slip-off weight containers complete with the brand new and patented Lock-Aid-System with mechanical safety release for rapid extraction; each one can stow up to 4.5 kg of weight.
The shoulder straps are separate from the bag, which provides considerable buoyancy as required by the models with fully integrated weights.
Notwithstanding this, the mixed front-back volume and the anatomic conformation guarantee an extremely streamlined and enveloping structure that is perfect for forward moving.
The extensive accessories include two accessory holder zip-up pockets, two weight pockets on the back, several stainless steel D-rings, two knife sheaths and two carry handles.
The choice of materials makes it possible to keep the weight down for air travel.
Notwithstanding the excellent buoyancy guaranteed by the mixed front-back structure of the bag, this wraparound jacket guarantees a particularly small forward moving section.
Considerable comfort is guaranteed by the anatomic padded back and by the two-piece elasticized waistband, extensively adjustable in length, complete with the famous Freematic Cressi system that stops the abdomen from feeling compressed even when it is fully inflated.
The integrated weights system uses large pockets that can be slipped off towards the front of the jacket, with the brand new, patented Lock-Aid-System, which makes extraction immediate and extremely easy, while still combined with anti-slip off safety.
The extensive accessories include two accessory holder zip-up pockets, two 50 mm D-rings on the shoulders, two on the bottom of the jacket, a knife sheath above each of the front pockets and two more weight pockets on the back.
There are three dump/pressure valves: one situated at the upper extremity of the hose, a second one on the right shoulder, controlled by the tubed line and a third one fitted to the bottom right rear of the jacket.
Although the structure is strong, the judicious choice of materials has made it possible to keep the weight right down for air travel.

BACK JAC BCD
In the new AERO range, this is the rear expanding model that offers the maximum buoyancy of all. The anatomic conformation of the jacket and the special elastic bag retainer keep the size smaller and ensure a favorable forward moving section.
Like the other models in the AERO series, it has been specifically designed to be able to stow all the diver's weights in the different pockets.
Complete with the brand new Lock-Aid System (L.A.S.), which consists of two special slip-off weight containers complete with the brand new and patented Lock-Aid-System with mechanical safety release for rapid extraction; each one can stow up to 4.5 kg of weight.
The extensive accessories include two accessory holder zip-up pockets, two weight pockets on the back, several stainless steel D-rings and two knife sheaths.
A judicious choice of materials has made it possible to combine its extreme sturdiness with a smaller weight for air travel.
The rear expanding bag offers extreme comfort without in the least interfering with the diver's body, irrespective of how inflated it is. The special elastic bag retainer guarantees quick deflation and at the same time keeps the volume to a minimum.
Considerable comfort is guaranteed by the soft covering made from special webbed material on the back and all along the inner jacket. The two-piece elasticized waistband, adjustable in length, comes complete with the famous Freematic Cressi system.
The integrated weights system uses large pockets that can be slipped off towards the front of the jacket, with the brand new, patented Lock-Aid-System, which makes extraction immediate and extremely easy, while still combined with anti-slip off safety.
The two large webbed, vertical accessories pockets are concealed and when not used they can be rolled up and protected by a zip.
