Scuba Diving Signals

Diving alerts are communication that divers use underwater with their fingers, due to the fact conversation underwater without special and high priced equipment is not possible.

Without figuring out humans use a whole lot of hand or body gestures to explicit themselves. Movements like shrugging the shoulders for “I do not know”, nodding the pinnacle for “Yes” and shaking the top for “no” are very common in our society. Also couples who’ve lived together for some time can communicate with body, eyes and arms and they do not need to speak to recognize each different.

All the indicators were created for better information between divers, due to the fact going each time to the surface to communicate is dangerous and a while there’s no time for writing the whole thing on a slate. The indicators were also introduced through navy divers inside the early years of scuba diving.

Beside the hand signals used underwater, divers at the surface use different diving alerts or gadgets to communicate.

The famous diver down flag (red with a white line across): shows that there may be a diver beneath. No different boats are allowed and there may be a second, large quarter in which boat’s pace is restrained. The flag can be located on a boat or on a buoy. And in some nations it have to move down when all divers are out of the water. Today this flag represents scuba diving international.

The Alfa Flag (white and blue): in worldwide transport communications every letter of the alphabet is represented by a colored flag. This flag represents the letter “A” Alfa. By itself approach “Diver Down; Keep Clear at slow velocity”. The flag have to be flown from any vessel that has diving operations happening which restricts ship’s maneuvers.

Surface marker buoys (SMB): Good for signaling boat drivers of your region while performing the protection stop or ascending. SMB makes boat drivers see you from some distance on the surface. The Yellow SMB it’s miles used extra commonly in tech-diving and manner emergency underwater/ need assistance (for the ones divers that need to spend hours on decompression stops).
