Two separate parts of a scuba helmet are the backplate (wing) and the wing (wing). Each piece is attached to a buoyancy compensator, which establishes positive buoyancy on the surface and neutral buoyancy underwater. Backplate, wing, and the rest of the system are modular. Each piece can be removed from the others. These are great options for divers who aren't certain which type they should get. Below are the pros and cons for each.
Stainless steel
With or without a helmet, the stainless steel backplate and wings can be made from either stainless steel. The wings and backplate are made from 316 stainlesssteel. This material is highly resistant against saltwater. It is cut by a CNC router and polished manually to prevent any sharp edges from causing premature wear. They can also be used with a single-air-tank system or dual-air-tank systems. For easier storage, the wings and backplate can be removed from stainless steel.
Backplates made from stainless steel are much heavier than those made of aluminium. Stainless steel backupplates are perfect for colder environments, as they'll help reduce the weight of your diving gear. Stainless steel backplates can be adjusted to fit most tanks, unlike lead pieces. A Halcyon Dealer is able to provide weighting advice and help you decide what weight suits your body. You don't have as many to replace the backplate.
Plastic
While the buoyancy of the plastic back plate and wing is negative, it is still advantageous when replacing the weight on the weightbelt. Jacket BCDs also have features such as pockets and weight integration. These ancillary options are not available on the backplate and wings. These components can be ordered separately. The pros and cons of each will be discussed in this article. It is vital to select the right backplate for your needs.
Softpack harness
There are many kinds of harnesses, both for wings or backplate. These include wing BCDs and backplates. They come with all the components needed, including a harness and backplate. Softpack BCDs can be used by technical divers because they are lightweight and flexible, and don't attach to any rigid plates.
The problem with steel backplate harnesses, however, is their inability to be adjusted. The harness is not intended to be used with single tanks. While the steel harness offers the most rigid option, it can be cumbersome when used for travel. In addition, it is only suitable for double tanks, and the steel backplate may be unsuitable for use on land. It can be converted to work with single tanks by attaching adapters, but this is not recommended.
