I dive with Wolfgang's students in advanced course in front of Serena resort. After three times empty lung warmups, I do deep diving to 45.7m, bad start but good timing for doing mouthfill. I found a way to hear the notify of doing mouthfill from my diving computer, which is doing equilizing by left hand. It is closer to my ear. At the bottom, I still have some air in the mouth, it means I can go deeper easily. But last 10m I ascent too fast, I feel some dizzy.
