Important Hand Signals You Must Learn For Scuba Diving

The skill of underwater communication is an essential skill you need to learn for scuba diving in Cancun. There are several important signals that can be life-saving. These signals are not difficult to learn. You are already familiar with many of these gestures. So, let’s learn the most important scuba diving hand signals. 

The ‘OK’ Signal

This is a demand-response signal used to respond to a question and ask a question. For example, you can use this signal to ask if the other diver is OK. You can use the same signal to tell that you are OK. To give this signal, form a loop by joining the index finger and thumb and then extend the remaining fingers.  

The ‘Problem’ or ‘Not OK’

To communicate a problem, flatten and extend your hand and rotate it side to side. After that, use your index finger to point to the problem or source of the problem. For example, after giving this signal, point to your ear to communicate the ear equalization problem. 

‘Problem’ and ‘OK’ on the Surface Signal 

These signals involve the use of the whole arm so that someone can understand the communication from far away. You can make the “OK” sign by joining both arms above the head to make a ring. If one hand is busy, you can use the free hand to touch the top of your head with the fingertips. You can call for attention by waving your arm overhead to indicate a problem. 

‘End The Dive’ or ‘Up’ Signal 

You can use the thumbs-up sign to communicate ‘end the dive’ or ‘up.’ It is an important demand-response scuba diving signal.      

‘Down’ Signal

The thumbs-down hand signal is used to communicate “go down.” This indicates that the diver is prepared for a deeper dive. 

‘Slow Down’ Signal 

This signal is used to tell the diver to swim slowly. You can give this signal with palm-down position and hand motioned down. It also helps in avoiding dangerous underwater behaviors such as hyperventilation. 

‘Stop’ Signal 

There are two methods for communicating “stop.” In the first method, you can hold a flat hand with palm facing forward just as traffic cops do. 

Technical divers prefer the “hold” sign. You can make this sign by extending a fist with the palm-side facing outward. This is also a demand-response signal. 

‘Look’ Signal 

You can give this signal by pointing the third finger and index finger at your eyes. And then, you can use your index finger to point towards an object. 

‘Go In This Direction’ Signal  

This signal is used to indicate the direction of travel. Divers flatten their hands and use their fingertips to point out a direction.     

‘Come Here’ Signal  

To give this signal, you can flatten your hand with palm-up position and bend your fingertips upward toward yourself. 

‘Level Off’ Signal 

This signal is used to tell the diver to maintain the current depth. Usually, this sign is used when divers reach the planned maximum depth. To give this signal, extend and flatten your hand with palm facing down. Now, slowly move your flattened hand side to side. 

There are several other signs you have to learn for scuba diving in Cancun. You will learn these signs during your scuba diving classes.
