What are the diving hand signals
There are numerous diving hand signals that divers use to communicate underwater. Here are some commonly used ones:
1. OK: Forming a circle with your thumb and index finger.
2. Up/Ascend: Extend one arm upwards with a closed fist and move it up and down repeatedly.
3. Down/Descend: Extend one arm downwards with a closed fist and move it up and down repeatedly.
4. Stop: Hold one hand flat, palm facing outward, and move it back and forth in front of your body.
5. Look: Point your index and middle finger toward your eyes.
6. No/Don't: Extend one arm out with the palm facing down, and move it side to side.
7. Go/Continue: Point your index finger in the direction you want to go.
8. Problem/Help me: Wave one arm back and forth horizontally above your head.
9. Air/Out of air: Tap the top of your head with a flat palm.
10. Buddy check: Point both index fingers together and move them side to side in front of your body.
It's important for divers to learn and understand these hand signals to effectively communicate and ensure their safety while diving.
