 We should recall that when it comes to diving it may be considered as a group action. One of the deciding element of a well performing group is the effective communication between its course, many sort of portable radio devices may explain the problem, but electronic systems are not very attractive. In recreational diving is still attractive to communicate by a hand gestures. The most casual hand are command marks.
These marks require a back talk. We have three command marks:
a.Ok the use of the ok signal does not change from its known above water application. Like all other command marks, the ok sign must be feedback, either with an
affirmation or an evidence of the difficulty if the one happen.
b.Stop/hold failure to properly identify and acknowledge the hold command can be hazardous. Misunderstandings relating to the hold
command have resulted in few confusing places and a least one death. 'Stop' is communicated with an open palm.
c.Exit when communicating that a dive is gone, divers must be especially clear. Dives can be
gone for few reason: because a team member has completed thirds, or because he is uncomfortable, cold, or feeling not healthy. The moment the exit signal is given, every diver is required to get feedback in kind, and begin to exit the overhead. To reduce confusion, most divers use the thumb up.
We may talk, that effective communication, is something which cement a group of a divers. When it comes to effective mutual effort hand marks, light communication, and electronic channels are extremely necessaryessential. Talking about attractive hand marks used by divers to communicate we may take under our consideration the following signs:
1.out-of-air That gesture is done, by drawing the hand across the throat. Of course, the out of air signal asking instantaneous attention. Upon receiving this out of air, divers should prepare
to gice air while quickly approaching the out-of-air diver.
2.Silt Upset of the fundamental sediment , may be indicated by rubbing the thumb traversing the ends of ones fingers while holding the hand in a palm-down posture. A divers may opt to use this signal to communicate to other divers that they are disturbing the fundamental condition, or to give a notice the team of a specifically susceptible area.
3.Light is on divers should periodically look at other divers to verify that t is all ok with their equipment, and to determinate whether are any irregularities, such as an reserve light activated by accident.
4.Safety stop it is suggest that on all dives, regardless of decompression obligation, divers execute at least a three minute safety stop. One usually used sign to indicate a safety stop is to hold a fist with a raised pinky finger.
5.Line the middle finger crossed over the index finger is a usually to indicate the line. A diver may communicate more specific information about the line with signal used in conjunction with this signal.
6.Bubbles in order to indicate the presence of bubble, the diver holds out one hand and rings the index finger on to the thumb in a repetitive motion with the amount of distance increasing to indicate larger bubbles.
During loss of seeing under water, light and hand marks while we are diving, become useless. Divers must resort to physical contact to communicate with one another. If entangled in the line, divers can communicate a this by crossing the middle and index fingers, an placing them in a dive buddy hand, twisting them back and forth. In touch contact, both divers should be on the line and in contact.Therefore, to
communicate a line entanglement, a diver can simply follow the line up to the dive buddys hand, and using the space former by the divers hold on the line, insert his own signaling fingers therein. In back talk, divers can acknowledge this entanglement by firmly squeezing the entangled divers hand on the line.
