BCD completely modular

This buoyancy compensator is provided with an AUDAXPRO Technical Modular System (T.M.S.), which allows changing the BCD standard configuration according to your needs. Thanks to the Audaxpro T.M.S. you can shape, configure and integrate your BCD as you like. You can, for example:

Adapt your jacket to your physical shape

Adapt it according to the type of immersion

Change its components with any other Audaxpro BCD ones

Upgrade your equipment with a wide series of accessories

BCD with a totally adjustable and super-accessorized harness

AREA51 is a technical buoyancy compensator with a variable structure. It has a comfortable, fully equipped and anatomic harness. It is a Wide Fit scuba BCD, so it covers up to your pelvis. This feature makes it longer than any other Audaxpro BCs, with the exception of the ELEVEN (which is similar to it), and longer than any other BCD on the market. Moreover, its special harness can be easily set and adjusted to your body while wearing it. The BCD total adherence to your torso gives you a great stability and influences positively your posture helping your swimming and consumption while diving.

More info

The preformed harness of this great scuba BCD is entirely made of padded cordura with a soft 2,5-mm pre-compressed expanded polystyrene layer. It is possible to adjust its height with 2 stainless steel buckles placed on the BCD anatomical shoulder straps. The harness and the anatomical shoulder straps are both blocked and adjustable through 2 stainless steel buckles, they are also secured with Velcro. You can fasten and unfasten the jacket shoulder straps through 2 50-mm nylon fasteners. The shoulder straps have 2 50-mm stainless steel D-rings and as these rings are not sewn, you can adjust the straps as you prefer. You can set them also thanks to a HT polyester strip tightening the anatomical shoulder strap to the harness. Moreover, the anatomical shoulder straps are equipped with 2 stainless steel little rings each, which help adjusting the breast line. In the part adjacent to the bladder, there is a HT polyester strip vertically placed at the harness centre, where there are also 3 stainless steel grommets (2 in the higher and 1 in the lower part). Right and left to the central strip there are 2 other strips divided by seams that form some slots. The latter ones make the BCD lighter (SOFT version). This BCD is equipped with 8 stainless steel grommets, 4 on both sides of the harness, and 4 latex rings that can be used to tighten the long hose or the canister. Your diving will be comfortable. In fact, if necessary, you can replace the BCD ventral belt placing 2 rectangular 50-mm nylon rings (on the lower part), at the ventral part level. The ventral belt is equipped with 2 50-mm stainless steel D-rings to hook the decompression tanks. There are 6 25-mm stainless steel D-rings and 2 50-mm stainless steel D-rings to fix some accessories. The harness of this scuba BCD is also equipped with a 50-mm stainless steel D-ring to transport the BCD in the water or on board. Thanks to an anatomical plate padding, the plate of this scuba BCD is more comfortable. Inside the plate padding there is an inner pocket for the lift bag or the signal tube, fixed with 4 stainless steel screws. A rectangular 50-mm nylon ring, placed centrally in the lower part of the harness, is there for fixing the inguinal belt, which can be adjusted through a 50-mm nylon back buckle. A stainless steel buckle allows closing the ventral belt of the jacket. Next to the buckle, there is a loop with a 25-mm stainless steel D-ring that can be used to anchor the scuba BCD to the boat. 

A different version for every different need

Audaxpro BCDs have been designed to ensure the best performances in every kind of diving immersion. For this reason, AREA51 is available in different versions, one for every different need. This is only possible because the Audaxpro BCDs are built by combining high technology and skilled Italian craftsmanship.

Choose your BCD with the suitable buoyancy force

The buoyancy compensator AREA51 can face any kind of immersions and any depths, including the extreme ones. Audaxpro gives you the possibility to choose the BCD AREA51 in the suitable buoyancy thrust for your scuba immersions. You can opt for a monotube version of 30, 40 or 50 litres with 2 overpressure and rapid-discharge valves or between the double-tube models of 30+30, 40+40 or 50+50 litres. Thanks to its double air chamber, to the 4 overpressure and the rapid-discharge valves, the double-tube system increases the scuba jacket safety level, which is already assured by the quality of Audaxpro materials and their production technologies.

More info

The outer bladder of this scuba BCD is made of cordura, while the inner bladder is made of TEXTANE A/B 210 nylon. If necessary, you can replace the jacket inner bladder thanks to a zip placed in the higher part of the bladder. Under the zip, there is a polyester protection for the inner bladder and the zip slider can be concealed. In the central part of the BCD bladder, there are 4 cuts to lighten the jacket, 12 stainless steel grommets to tighten the latex rings and a HT polyester strip, vertically placed at the bladder centre. Right at the centre of the bladder, this diving jacket also presents 3 stainless steel grommets, 2 in the higher and 1 in the lower part of the bladder. The big strips on the bladder sides have slots to pass and tighten the 12 latex bands (3×8, 14 in the 50-liter version). The latter ones are necessary to adjust and empty the BCD air chamber.

Balance the BCD weight according to your equipment

Thanks to the Audaxpro technical modular system, you can set differently the weight of your scuba BCD according to the equipment you choose for every immersion. The AREA51 buoyancy compensator can be bought or used with plates (Plate versions) as well as without them (Soft version). In the Plate version, you can opt for a stainless steel plate and back plate to increase the jacket weight, or for a plate and back plate made of anodized aluminium to diminish it. There is an anatomical back plate padding, which ensures you the best comfort. The back plate padding has an inner pocket to keep the lift bag or the signal tube.

More info

Choose the perfect pocket for your BCD

With Audaxpro, you have the opportunity to choose among many different pocket models for holding ballast and/or other containing objects. All Audaxpro pockets are available in 8 different colours. You can choose the one that matches better your AREA51 BCD.

More info

The pockets of this special scuba BCD are made of cordura 1000. In the AREA51 standard configuration, there are 2 different models with a weight capacity of 5 kg: a horizontal one (6,5x20x14 cm) and a vertical one (6,5x14x20 cm). Every pocket of this jacket has a double opening, a higher and a lower one. There are 2 zips allowing the opening of this diving BCD. Inside the pocket, there is a dividing panel of cordura 1000, so that you can use it as an object holder (the higher part) or as a ballast holder (the lower part). You can fix the pocket on the ventral belt of your jacket passing a strip through 2 50-mm stainless steel buckles and through a slot sewn on the pocket back. A stainless steel screw, passing through a stainless steel grommet placed on the pocket back, ensures that the pocket is tightened to the BCD harness. It is also possible to assemble other pocket models (optional) on your BCD choosing one among the whole Audaxpro pocket collection.
