This is second fundive at Pattaya with dive info after finishing Advance+nitrox. The first dive is shallow but it gave me another experience of scuba diving.
I rented all equipments with the dive shop. And, the regulator give me air too much. So, my air was run out quickly. At the end of dive, 20 bar, I would ask for air from my buddy. So, this is the first time of my alternate air source but not follow the protocol of alternate air sauce.
