The backplate and wing setup, an alternative to the traditional jacket-style BCD, offers divers enhanced freedom of movement and easier access to equipment, making it a favored choice for many technical divers and those engaging in advanced underwater explorations.

Backplates come in various sizes and thicknesses to accommodate different body types and diving needs. Features such as mounting holes for attaching gear, varying plate thicknesses, and the choice between a metal or a soft backplate cater to diverse diving styles. Whether diving in warm tropical waters or engaging in deep cold-water expeditions, the backplate is an integral piece of equipment that offers both safety and comfort.

Understanding Scuba Backplates

Scuba backplates are a crucial component in a diver’s gear, offering a stable mounting point for tanks and enhancing diver comfort through their design and material composition.

Materials and Design

Scuba backplates are constructed using durable materials such as stainless steel and aluminum. Stainless steel backplates are heavier, which may negate the need for additional weight, while aluminum backplates are lighter, suitable for travel and warm water diving. The design of a backplate can greatly affect diver comfort and performance. Some backplates feature a contoured design to better fit the natural curves of the diver’s body, offering enhanced comfort and reducing strain during extended periods underwater.

Sizing and Fit for Divers

The fit of a backplate is just as important as the material. Proper sizing ensures comfort and stability, reducing the likelihood of the gear shifting during a dive. Although most backplates come in a standard size, some manufacturers offer multiple sizes, like a smaller version for divers with shorter torsos. The right size allows the waist strap to sit on the diver’s waist and the shoulder straps to stay securely in place instead of sliding off the shoulders.

• Ensure the backplate sits flush against the diver’s back without any gaps.
• Select a size that positions the waist strap correctly and keeps shoulder straps in place.

Harness Systems and Configurations

In scuba diving, harness systems play an essential role in securing the diver’s buoyancy control device (BCD) and tank. These systems are designed for a snug and customizable fit, ensuring stability and comfort underwater.

Harness Types and Features

Harnesses typically come in a variety of configurations, where webbing material, adjustability, and attachment points are central to their design. They can be categorized mainly as:

• Padding: Some divers opt for additional padding on shoulder straps for comfort, although this may vary depending on personal preference and dive conditions.

Crotch Straps and Cam Bands

Crotch Straps are an integral part of a harness system:

• Prevent the BCD from riding up while diving, enhancing stability.
• Generally adjustable and can feature loops for accessory attachment.

Cam Bands secure the scuba tank to the BCD:

• Usually made of heavy-duty nylon and include a buckle for easy fastening.
• Can be single or double, depending on the diver’s setup requirements.

These two components are critical for ensuring that the diver’s gear remains in place throughout their underwater exploration, providing safety and reliability.

Wing and Buoyancy Control

The wing is a critical component in a backplate and wing (BPW) buoyancy compensator device (BCD), providing essential lift to maintain control underwater. It is crucial for divers to understand how the wing and its bladder system work in conjunction with the backplate to achieve precise buoyancy control.

Bladder Types and Lift Capacity

The bladder of a wing BCD is responsible for providing lift underwater. Bladder types are typically categorized as:

• Single Bladder: Suitable for recreational diving, it offers one chamber for inflation.
• Dual Bladder: Used in technical diving, it provides redundancy with two separate chambers.

Lift capacity, measured in pounds (lbs) or Newtons (N), varies according to the wing’s design and purpose. It must be chosen based on:

1. Dive Environment: Deeper or more demanding dives require higher lift capacity.
2. Dive Gear: More equipment necessitates a wing with greater lift.

A typical lift capacity range is:

• Recreational diving: 20-40 lbs (90-180 N)
• Technical diving: 40-60 lbs (180-270 N) or more

Wing to Backplate Attachment

The wing attaches to the backplate using a secure and durable system, typically involving:

• Bolts and Grommets: Stainless steel bolts pass through grommets on the wing to affix it to the backplate.
• Book Screws: Sometimes used in place of bolts for easy assembly and disassembly.

This attachment must be reliable to ensure that the wing does not shift or detach during a dive. Proper alignment of the wing to the backplate is crucial for balanced buoyancy control. Divers must routinely inspect these connections for any signs of wear or damage.

Accessories and Customization Options

Customizing a scuba backplate allows divers to tailor their gear to specific diving activities and personal preferences. With a variety of pockets, D-rings, and expansion options, one can enhance functionality and compatibility of their rig.

Pockets, D-rings, and Expansion

Scuba backplates can be equipped with a range of pockets and D-rings. These additions serve for storage and attachment points for various diving accessories. Surface Marker Buoys (SMBs), lights, and spools can be conveniently attached, ensuring immediate access when needed. Expansion of a backplate setup often involves Single Tank Adapters (STAs) which provide stability and weight distribution for a single tank setup.

• STA: Offers firm mounting for a single tank
• Pockets: Useful for carrying extra gear, like lift bags
• D-rings: Allow for the attachment of accessories

Personalizing Your Rig

When personalizing a dive rig, divers should consider the accessories that match their diving style.
