Building on the expertise and experience of the Stealth 2.0 Classic and designed around the popular Stealth harness and weight management system, the Stealth 2.0 TEC offers perfect streamlining and balance with its high capacity lift wing which can easily support  multiple cylinders that any kind of advanced diving requires. The TEC BC bladder is a double-shell structure  with the outer shell made of Cordura 1100 dTEX which provides the highest level of safety for wreck/cave diving. The Stealth 2.0 TEC BC also has a unique multi-chamber design to fit the body tightly, regardless of how full it is. Its anatomical shape makes it extremely comfortable, ensuring that the movement and position of  gas can be properly managed at all stages/depths of any dive.

Future proof: From ocean diving to caves

The xDeep Stealth TEC sidemount system is set up around the proven and unparallelled simplicity and versatility of the popular Stealth sidemount Harness. The system combines the Stealth 2.0 easily adjustable harness and spine weight management system with a new design twin shell 19Kg (42Lbs) TEC wing which can be mounted on the harness in a streamlined and compact way whether fully inflated or empty. The combination allows for perfect rig balancing and diver trim supporting any tank configuration and multiple cylinders. (Please note: Manufacturer recommends not exceeding 8 cylinders on the unit).

Designed specifically for multi tank technical diving

Technical sidemount diving has experienced an explosion of popularity in recent years. Whether on wrecks or in caves, technical divers look to go deeper for longer and to be able to efficiently and safely carry multiple cylinders to support their dives. Sidemount offers many open water advantages. Building on XDeep’s expertise and experience from the STEALTH 2.0 classic, the STEALTH 2.0 TEC promises to be the perfect solution for technical sidemount diving.

Tested and proven design

The birth of the STEALTH 2.0 classic began a revolution in sidemount diving which continues to this day throughout the world. Three years after the classic, XDeep decided to make the worlds best sidemount system even better. As a base XDeep uses the outstanding STEALTH 2.0 harness and weight management system so that all STEALTH components can be seamlessly compatible. In doing so, XDeep has not only retained  the perfect streamlining and balance of the Classic, but done so with a wing that now offers additional lift to cope with the demands of deep, multi-cylinder technical dives.

Dive deeper, longer, safer

The STEALTH 2.0 TEC was designed to excel in deep decompression diving and in extended cave penetrations. 19Kg of lift in the wing can easily support the multiple cylinders that advanced diving requires. Increasing the STEALTH 2.0 buoyancy meant ensuring that the movement and position of the gas could be properly managed. The STEALTH 2.0 TEC BC does this brilliantly, keeping the diver stable, balanced and in trim, whatever the level of inflation.

More lift, even more streamlined

Increasing the lift of the BCD whilst maintaining and even improving the streamlining required a complete rethink on wing design. XDeep’s new solutions offers a spectacular result. Multiple cylinders are now easily supported with this design, even if they are large volume heavy steels or cave filled. At the same time, the STEALTH 2.0 TEC is incredibly slender, even when fully inflated.
Buoyancy control while in trim
Many sidemount BCD’s place the dump valve on one side or the other. Releasing gas from these systems requires a roll onto the diver’s side, which could be done in a basic 2 cylinder configuration, but may require considerable effort when carrying multiple cylinders due to changes of trim and balance that it requires,  By placing the dump valve in the centre of the STEALTH 2.0 TEC wing, divers can release excess gas with either hand, and stay in perfect trim while they do so.

Adjustable feed location for Inflator

Depending on how a diver likes to configure hid/her sidemounts, low pressure inflation feeds usually run off the left and right main cylinders, one to the wing and one to the drysuit. Divers can choose which side they prefer the wing feed to come from with the Stealth 2.0 TEC.

Protection where its needed

If you are going to catch any part of the system in a narrow wreck passage or cave restriction, it will probably be the upper part of your back first. XDeep has thought ahead and reinforced the upper part of the BCD, improving the fit to the divers back and eliminating snagging hazards making it safe, functional and secure.

OPTIONAL: xDeep Quick Release (Buckle) Kit for Stealth 2.0

The optional xDeep Quick Release (Buckle) Kit for Stealth 2.0 sidemount system allows you to quickly adjust the settings on the harness, fine tune it depending on your configuration and/or don or doff the harness without hassle. It’s easy to install. Components include 1x webbing, 2x webbing with plastic D-rings for pull, 2x tri-glides, 2x buckle sets, 2x retainer bands. You can order this together with the harness at an extra cost or purchase it from us separately. To order, please use the select box above.
