Applying advanced technology for a new dimension in sports diving

Inspired by a love of diving, engineered for maximum performance
We dive for different reasons, but whatever inspires us to take to the water, our gear must add to the enjoyment. Through meticulous design, by applying advanced materials technology and engineering expertise, the NX ZEN really does make us feel at one with the aquatic world.

Jump on any dive boat in the last 20 years and every BCD you see will be a slight variation on a theme. The NX ZEN is the result of our passion to break from that tradition, from what works, into what performs at a previously unheard of level.

Deconstructing traditional designs, bringing XDEEP’S technical diving experience and expertise, led to a step change in BCD design and application.


The NX ZEN is so named for a reason; that feeling of being ‘at one’ with the world that diving brings. Advances in materials technology, in diving design and our ability to apply modern engineering concepts created a dive system that delivered on our priorities.

A stable, comfortable and ergonomic BCD that is truly ZEN.


Modern BCD’s not only need to create a sense of freedom in the water but also provide security and confidence on the surface. Careful attention to the wing design and the balance point of the NX ZEN system means you are held comfortably and confidently whilst waiting for your boat pickup or sharing the excitement of the dive with your buddies,
NX Series

Built for unmatched performance and comfort.
Epic look is just a side effect.

At XDEEP we are passionate about doing things better, improving and refining our products. We want BCD’s to be safer, to be robust and reliable and to be more comfortable for divers. Our engineers and designers leave no stone unturned in the pursuit of this goal. From the overall design concept to the little details, everything is examined and improved. Once we have come up with the design we obssess about identifying and using the best materials.

The NX Series is the culmination of our experience, expertise and passion so far. The NX collection of products has already changed dive industry thinking and has improved diver experiences from exploration cave diving to tropical reefs.

Less is more

The ZEN wing is deliberately narrow so that it does not protrude from the side of your tank. This brings advantages in enhancing your buoyancy control, in reducing any entanglement hazards and in significantly reducing drag. As we reduce drag we usually improve our gas consumption, enabling longer and safer dives.

How is this possible?

Traditional wings have a large central ‘dead zone’. No air bladder, just fabric. By using this space for more effectively we have reduced the dead zone considerably which means we can reduce the overall bladder size.

LESS effort
MORE comfort and safety

The tight to the tank streamlining makes buoyancy control more precise. The wing shape adds stability due to reduced air migration and attention to the ideal balance for easy expert trim.

When diving in currents you want to reduce drag for ease of finning. When exploring swim throughs in a wreck or reef you want to be free of entanglement. This is where you will truly value the NX ZEN’s design.

A breakthrough at the top

As a result of the revolutionary inflator design, first seen on the NX GHOST we have been able to make a design breakthrough at the top of the wing. We have created a leaner and smaller shape, opening up space around the valves and hoses, reducing unwanted air migration and creating better balance for better trim.

Failure points have been eliminated as far as possible by removing all threads and gaskets. The material is completely resistant to any crushing or traumatic forces. A direct weld of the inflator to the bladder ensures a robust and direct connection for maximum performance.
Smaller Upper Wing Section
The compact engineering of the NX Series inflator has allowed a reduction in the required size of the upper part of the wing. This results in a position at the Surface that lifts you high out of the water and, ensures lift is in the right place when submerged.

Precise control of gas movement
Traditional inflation systems are mounted on the side, so that as gas is injected it can disturb trim if you are in a good flat position.

The compact nature of the NX series adapter allows it to be placed dead centre, eliminating unwanted gas movement. Air is added and is immediately distributed equally down both sides of the wing, leaving you in perfect trim.
Tailored to your tank
Removing the old fashioned angular inflator joint means we have been able to tailor the wing shape to perfectly fit your tank. Air flow around the wing and tank is more efficient and is optimally balanced to help you achieve perfect trim and precise buoyancy.

The classic back plates design history dates back to what could be cut out of an old road sign. For the first time since then we have looked properly at the ergonomics and anatomy of the back. The redesign has created a plate that is better in every respect.

Enlarging the upper part of the back plate has achieved better weight distribution during the dive and removes load from the lumbar region. The lower plate design, spreads the load comfortably safely allowing for the optimal attachment of weight pockets and accessories.

The new NX Series back plate is comfortable, stable and protective of your back.

ZEN, as with any other set from the NX Series is equipped with XDEEP’s perfect 3D Mesh lining.

This soft but non compressive pad adds to your comfort, whether in board shorts or drysuit. It helps prevent any small movement of the back plate against your back, adding to stability and security.
The 3D Mesh material does not need any additional lead due to the smart materials technology that allow easy water penetration and drainage.


The back plate design has resulted in major improvements in donning and doffing the system.

When the harness is unfastened, the shoulder straps are 20% longer than in a classic harness. This creates more room even if you have restricted movement in the shoulders. Tightening the buckle of the waist strap pulls the shoulder straps snugly down, perfectly tensioning the harness fit to your body. No need to adjust for changes from wetsuit to drysuit. The whole system is comfortably held closer to your body stabilising the entire scuba unit.

V-shaped crotch strap

The NX Series harness is equipped with totally new V shaped crotch strap.

The V shape is more comfortable, eliminating the single strap design running directly between the legs. Whether walking with your gear to jump in or scootering around a reef, you will feel the very direct benefit.
The V-shaped crotch strap distributes load over a larger area, allowing you to sit comfortably into the crotch strap whilst at the Surface.
The V is formed by two attachment points at the bottom of the back plate. This ensures there is an even tension preventing sideways slippage of the system and spreading the load for stability.
The NX Series V-strap is equipped with two Cargo D-Rings instead of the usual one. The design results in the D rings being set off to each side as opposed to a traditional centre ring, providing easier access to clipped off gear.


To truly be at one with your equipment, your weight system must be perfectly balanced, be secure and easy to configure and use. The modular weight system in the NX series means you can confine your weight belt to history.

Simple to use

Even in bulky gloves the weight pocket can be quickly and easily removed and passed up onto the boat. Pockets are made in two parts with the weights fitting into separate slots. This ensures the weights are secure, cannot fall out accidentally and stay exactly where you want them.

Drop weights only when you want to

Robust ITW Nexus buckles snap into place with a solid click, reassuring you that your weights for that dive are solid and secure. Unintentional weight loss and a resultant rapid ascent is a serious risk, best eliminated.

Should an incident demand dropping your weights, the buckles construction and size make it simple and very quick.

Look after the environment

Whilst lead is useful to divers given its high mass to volume characteristics, it carries some environmental considerations. In air lead forms lead oxide, a carcinogenic compound that can pollute enclosed air spaces such as cars and boats. The oxide forms on each lead block surface as it is used.

Once lead is installed in an XDEEP pocket the pocket design and material provides effective protection.

Details make a Difference

Throughout the NX series it is the attention to detail that separates our products from the rest. On the weight pockets a rigid edge makes it easy to keep the pocket open to add weights – even underwater. The difference is in the detail; the result is in the performance.
