For this, a lot of equipment is required. Besides a mask, mouthpiece and flippers, you've got to wear a wet suit to prevent injury and keep you warm and lug a large tank of pressurized oxygen and a breathing regulator. And you've got to wear a special diving buoyancy compensator, as well as a weight belt, lead weights, a diving sheath, and so on.
所需的裝備就多了，除了面鏡、呼吸管、蛙鞋以外，必須穿上可防止在海中受寒受傷的潛水衣，還有儲存大量壓縮空氣的氣瓶、呼吸調節器、和可以在水中充排氣的浮力調整救生衣，以及配重帶和鉛塊、潛水靴等等，這些背在身上的裝備加起來有二、三十公斤重。
