How BCDs are made?

Imagine scuba diving while hovering, weightless underwater – eye to eye with a fish. How is it possible? It starts with your buoyancy control device (BCD). But have you ever wondered how it’s made?

A BCD does exactly what its name describes – it gives you control in the water. Sometimes you want to float on the surface comfortably. Occasionally, you want to kneel or stand on the bottom, sometimes during a training course. Most of the time, you want to drift along effortlessly mid-water, observing the scenery. To do this efficiently, you need a BCD that fits you well, along with a weight system to fine-tune your buoyancy. The BCD also holds your tank.
