The backplate and wing are two separable components of a scuba harness. Both are attached to a buoyancy compensationator which creates buoyancy below and above water. Backplate, wing, and the rest of the system are modular. Each piece can be removed from the others. They are a good option for scuba divers that aren't sure which type to get. Here are the pros and disadvantages of 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. You can use them with either 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 backplates are ideal for colder climates where they will decrease the weight that you'll be carrying during your dive. Unlike lead pieces, stainless steel backplates are easy to adjust to fit most dive tanks. A Halcyon Dealer is able to provide weighting advice and help you decide what weight suits your body. You won't need to replace this backplate as often because it will last longer.
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 come with pockets and weight integration. These ancillary options are not available on the backplate and wings. These components can be purchased separately. This article will discuss the pros and cons of both. It is vital to select the right backplate for your needs.
Softpack harness
There are many different types of wings and back plate harnesses. The most popular are wing BCDs (backplates) and wing plates. 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. This harness is not suitable for single tanks. It is only compatible with double tanks with permanent bands. The steel harness is the most rigid option but is clumsy to use when traveling. The steel harness is only compatible with double tanks. Additionally, the steel backplate may not be suitable for use on land. Although it can be used with single tanks by attaching adapters this is not recommended.
