浮力控制是所有潛水員致力追求的技巧，擁有良好的浮力控制，才能在水中隨心所欲地潛游。
越淺水越難控制浮力，而懸浮不動，更是難上加難。 今次我會示範潛水長技巧，如何在2.2米深度的水中以口吹式充氣Bcd並懸浮60秒
Buoyancy control is one of the most important skills in Scuba Diving. Only with good buoyancy control you can dive freely under the sea
The shallower the water, the more difficult it is to control buoyancy, and suspend motionless is even more difficult. This time, I will demonstrates a Dive Master skills (orally inflate the Bcd and hovering for 60 seconds) in a pool with 2.2m depth

其實這片段主要是潛水長學生練習示範技巧用， 如果想睇我哋入門潛水班Open Water同學仔做得如何， 可以點入以下片段喔😄
或者你不會相信，他們全是第一次穿起潛水裝備在泳池練習的新手👍
This video is mainly for the Demostration skill training of Dive Master Candidates. To see how Entry level Open Water students are doing, you can click on the following video 😄
You may not believe that they are all newbies who wear diving gear to practice in the pool for the first time👍

冇錯， 但一般open water學生(入門級課程 )，都係要做同樣技巧，只不過唔需要咁多手勢(數時間等等) 及只係需要做30秒
想睇學生做浮力 (懸浮同游動)
可以睇下面呢條片
