Two separate parts of a scuba helmet are the backplate (wing) and the wing (wing). Both pieces are attached to a buoyancy compensator that establishes neutral buoyancy underwater and positive buoyancy on the surface. The wing and backplate are modular systems that can be disassembled from each other. They are a good option for scuba divers that aren't sure which type to 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. Backplate and wings made from 316 stainless-steel are highly resistant to saltwater. It is cut with a CNC machine and polished manually to avoid sharp edges that can prematurely wear the strap. These can be used with either a single or dual-airtank system. 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 backplates are ideal for colder climates where they will decrease the weight that you'll be carrying during your dive. Stainless steel backplates fit all types of dive tanks better than lead pieces. A Halcyon Dealer can provide weighting advice to determine what's appropriate for your body weight. You won't need to replace this backplate as often because it will last longer.
Plastic
The buoyancy of the plastic backplate and wing is not good, but it is still beneficial when replacing the weight on your weightbelt. Jacket BCDs include 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 crucial that you choose the right type and size of back plate to suit your needs.
Softpack harness
There are many types of harnesses available for wings and back plates. Backplates, wing BCDs, and the most common are both available. They come with all the components needed, including a harness and backplate. Softpack BCDs, which are lightweight and flexible, are great for technical divers.

The problem with steel backplate harnesses, however, is their inability to be adjusted. The harness is not designed to work with single tanks and is only suitable for double tanks with permanent bands. The steel harness, while the most rigid, is also very cumbersome and difficult to use during travel. In addition, it is only suitable for double tanks, and the steel backplate may be unsuitable for use on land. You can attach adapters to make it compatible with single tanks. However, this is not recommended.
