1) Clearing the pressure from your ears under water
2) Clearing your eye mask when water enters
3) Taking out your regulator, blowing bubbles, putting it back and clearing the water.
I wast pretty stucked for point 3 :( I was quite a loser and took very long to master it. I'm really thankful that my instructor was very patient with me :) If its your first time, can try booking from Amazing Borneo Tours for an amazing experience.
During the dive, we went down to around 10-12metres deep. As a loser, i was worried that my regulator will fall off as im not very confident with point 3. So i hold onto my regulator all the way during the 45mins session. hehe
It was an amazing first time for me! And still thinking about taking PADI Open Water Course.
