BCD completely modular

This jacket 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

A BCD with a technical-functional harness

AREA51-TEK is a jacket with a variable structure. It has an essential but highly functional harness, specifically designed for technical immersions.

More info

The harness of AREA51 is more comfortable and practical than the one of this more performing scuba jacket, which has HT polyester straps anchored to the plate. The plate is more comfortable thanks to an anatomical padding plate, which is fixed through 8 stainless steel screws, and it has an inner pocket to keep the lift bag or the signal tube. You can adjust the higher part of the harness and the ventral belt passing the straps through the plate cuts. The higher part of the band, passing through the plate cuts at shoulders level, is reinforced through a HT polyamide strap, which is sewn to the band. At the centre of the band, there is a stainless steel grommet, which serves as a barycentre, and to fix the harness to the jacket bladder. To make the scuba BCD band more comfortable, next to the shoulders, there are 2 shoulder straps (made of Cordura 1000). Each shoulder strap has 2 50-mm stainless steel D-rings and as these rings are not sewn, you can adjust the straps as you prefer. A stainless steel weight fixing blocks the ring. In the higher part of the shoulder strap, this jacket has a 60-mm OR to be used as an inflator holder. You can adjust the height of the shoulder straps. They are bound to the rest of the band through 2 50-mm stainless steel D-rings, where there is also the breast line. You can fasten and unfasten the jacket shoulder straps through 2 50-mm nylon fasteners in the lower part, almost at hips level (under the breast line). The ventral belt is equipped with 2 50-mm stainless steel D-rings to hook the decompression tanks. You can fix the inguinal belt through the horizontal cut in the plate lower part. 2 stainless steel weight fixings block one part of the ventral belt, the one passing through the plate cuts. To prevent the 2 stainless steel weight fixing from touching the plate, there are also 2 nylon weight fixings. A stainless steel buckle allows closing the ventral belt of the jacket. Next to the buckle, there is a slot with a 25-mm stainless steel D-ring to anchor the scuba jacket 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-TEK is available in different versions, one for every different need. This is only possible because the BCD Audaxpro are built by combining high technology and skilled Italian craftsmanship.

Choose the most suitable textile for your immersions

  • Standard model made of highly resistant textile (cordura)
  • Suitable for technical scuba immersions but also for recreational diving
  • 8 different colours
  • BCD with reflective textile (scotchlite)
  • Suitable for night immersions or diving with low visibility; ideal BCD for scuba guides
  • 8 different colours
  • Made of an anti-cut and fire-resistant textile (kevlar)

  • 1 available colour

Choose your favorite color for your BCD

The GAV AREA51-TEK is available in 8 different colors (except Kevlar model). You can choose between black, white, blue, red, yellow, orange, fuchsia and camouflage

Choose your BCD with the suitable buoyancy force

AREA51-TEK jacket can face any kind of immersions and any depths, including the extreme ones. Audaxpro gives you the possibility to choose the BCD AREA51-TEK with the suitable buoyancy thrusts 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 the double air chamber, to the 4-overpressure and rapid-discharge valves, the double-tube system increases the safety level of this scuba jacket, which is already assured by the quality of Audaxpro materials and their production technologies.

More info

The inner bladder of this scuba BCD 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 BC 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 there, at the centre, this diving jacket presents also 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 latex bands. The latter ones are necessary to adjust and empty the buoyancy compensator air chamber of this scuba jacket.


Buoyancy thrusts: 30, 40 or 50 litres

Tank maximum capacity: 20 mono-tank or 20+20 bi-tank

Overpressure and rapid-discharge valves: 2

Double Tube

Buoyancy thrusts: 30, 40 or 50 litres

Tank maximum capacity: 20 mono-tank or 20+20 bi-tank

Balance the BCD weight according to your equipment

Thanks to the Audaxpro technical modular system, you can set the weight of your scuba BCD according to the different equipment you may choose for every immersion. AREA51-TEK buoyancy compensator, differently from AREA51, can only be used with plates because the jacket special harness is fixed exactly on them. Nevertheless, you can get a stainless steel plate and back plate if you need to increase the jacket weight, or a plate and back plate made of anodized aluminium if you want to diminish it. This BCD has an anatomical back plate padding, which ensures you the best comfort. The back plate padding has an inner pocket where the lift bag or the signal tube can be kept.

More info

This special scuba BCD is assembled either with a stainless steel plate (kg. 2,160) and back plate (gr. 690) or with an aluminium plate (gr. 730) and back plate (gr. 230). In the back plate, 2 big back strips are assembled to fix the diving BC tank. You can choose between 2 different types of big strips for this scuba jacket, one for mono (110 cm) and one for bi-tank (150 cm). On the strips, there are 2 non-slip rubber grips for the tank.

Choose the inflator you prefer for your BCD

The AREA51 BC has been designed to guarantee the best functionality during your diving performances. The inflator has been strategically placed, in order to save space, allow an immediate localization and simplify the use of this scuba jacket. Moreover, with AREA51-TEK BCD you can choose between 2 inflator models, one with simple curve connection, the other one with discharge valve and metal anti-fraying wire. Both have a piston control, a nickel-plated brass inner mechanism and derlin non-slip buttons.

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-TEK BCD.

More info

The pockets of this special scuba jacket are made of cordura 1000. In theAREA51-TEK BCD 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 jacket choosing one among the whole Audaxpro pocket collection.
