Metalsub Tank Harness

Metalsub Tank Harness – Backplate and Continuous Webbing Harness for Single Tank Without Buoyancy Wing

What is Metalsub Tank Harness?

Metalsub Tank Harness is the traditional backplate system with continuous webbing harness designed and manufactured by Metalsub for very specific applications where a single cylinder needs to be secured safely and stably without the interference or bulk of a conventional BCD.

It is important to understand from the outset that this harness does not incorporate a buoyancy wing. It is not a substitute for a standard recreational diving BCD, but rather a specific tool for situations where buoyancy control is managed by other means —drysuit, precise weighting, or an independent wing— and what is needed is solely a robust, low-profile, fully adjustable cylinder retention system.

Low-Profile Rigid Backplate

The Foundation of a Stable and Minimalist Configuration

The central structural element of Metalsub Tank Harness is its low-profile rigid backplate, ergonomically shaped to conform to the natural curvature of the back:

• Elimination of tank swing – The rigid backplate creates a solid, direct connection between the diver's body and the cylinder, eliminating lateral movement and tank shifting that affects balance and hydrodynamics
• Minimal profile – By not incorporating a buoyancy bladder, the assembly has the smallest possible profile, ideal for confined environments or tasks where equipment volume is a critical factor
• Improved posture and balance – The cylinder remains perfectly fixed relative to the body, allowing a horizontal position to be maintained with less muscular effort
• Stable base for the harness – The backplate provides a rigid platform to which the harness anchors, ensuring that the entire system maintains its position throughout the dive

Fully Adjustable Continuous Webbing Harness

Precise Fit for Every Body Type and Every Application

The harness is built with high-strength 50 mm (2-inch) webbing in a continuous webbing system, with independent adjustment at four points:

• Shoulders – Correctly position the backplate on the back and distribute the weight of the cylinder evenly
• Chest – Keeps the shoulder straps in their correct position during active diving
• Waist – Anchors the system to the torso and contributes to weight distribution
• Crotch strap – The adjustable crotch strap is essential to prevent the harness from riding up in an inverted position or at the surface, keeping the system in its correct position in any body orientation

Integrated shoulder pads – Distribute the weight of the cylinder over a larger surface area, reducing pressure points and fatigue on long dives.

High-strength quick-release buckles – All closure points incorporate quick-release buckles that allow the equipment to be put on and taken off quickly and safely, even with gloves or in difficult boat conditions.

Cylinder Clamp with Cam Buckle

Secure and Slip-Free Attachment

The high-strength cylinder clamp with robust cam buckle secures the cylinder to the backplate throughout the entire dive:

• Firm attachment guaranteed – The cam mechanism locks the cylinder with constant and uniform pressure that does not loosen during diving
• Easy to operate – Opens and closes easily for quick cylinder mounting and dismounting
• Compatible with all standard cylinders – Sized to fit all standard single scuba cylinders on the market

Durability for the Marine Environment

Each component of the Metalsub Tank Harness has been designed to withstand continuous use in saltwater environments:

• Corrosion-resistant materials – All metal parts and buckles do not degrade with prolonged exposure to saltwater
• 50 mm high-strength webbing – Maintains its structural integrity and adjustment capacity after years of intensive use
• Durable backplate – Maintains its rigidity and shape throughout its entire service life without deformation

Who Is the Metalsub Tank Harness For?

Metalsub Tank Harness is a system without buoyancy bladder, suitable for very specific uses where a conventional BCD interferes or is not necessary:

• Underwater workers and professional divers – In underwater work where the cylinder needs to be secured without the bulk or interference of a conventional BCD
• Drysuit divers – Who use the drysuit itself as a buoyancy control system and only need a cylinder harness without an additional bladder
• Dives in highly confined environments – Where the minimal profile without a buoyancy bladder is essential for maneuvering
• Custom configurations – As a base to combine with an independent buoyancy bladder according to each user's specific needs

Important: This harness does not include a buoyancy bladder. It is not suitable for standard recreational diving without combining with an independent buoyancy control system.
