What feature do modern buoyancy compensators have to replace the traditional weight belt?

Modern buoyancy compensators often incorporate an integrated weight system, which is designed to replace the traditional weight belt used by divers. This integrated system allows divers to carry their weights within the buoyancy compensator itself, rather than on a separate belt.

The advantage of using an integrated weight system includes better weight distribution, which enhances the diver's overall stability and comfort in the water. Additionally, this system simplifies the process of donning and doffing gear, as weights can be securely contained within the buoyancy compensator and adjusted more easily. In the event of an emergency, the integrated system often allows for a quick release of weights, which can be crucial for buoyancy control and safety during a dive.

Other features such as an inflator, pockets, and a harness serve different functions; for instance, the inflator is crucial for adding or releasing air, pockets are useful for carrying additional gear, and the harness provides support. However, it is the integrated weight system that specifically replaces the traditional weight belt, addressing the need for convenience, safety, and better weight management.
