How do you signal out of air in scuba diving?
Clench your fist and draw it toward your chest. You tell your diving buddy you are almost out of air by signaling this to them.
Why do divers tap their heads with fist?
‘OK’ and ‘Problem’ on the Surface
The “OK” sign is made by joining both arms in a ring above the head, or if only one arm is free, by touching the top of the head with the fingertips. To indicate a problem the diver waves his arm overhead to call for attention.
What are the four E’s of diving?
PADI’s “Four E’s Philosophy” is that the dive lifestyle requires four elements: Education, Experience, Equipment and Environmental Conservation. Beyond simply learning to scuba dive, you expand your capabilities as a diver through continued education.
