Instructions

In the absence of any alternative method, manual signals by line are employed for all communications where two divers or a diver and an attendant are in contact by lifeline.

Manual line signals are of two kinds: PULLS .................Long, steady and distinct pulls. BELLS .................Short, sharp pulls made with the same timing as striking a ship’s bell.

All signals are to be preceded by one pull to attract attention.

All signals received must be acknowledged by repeating the signal (but only if the signal is clearly understood). (1) If a signal is not acknowledged or is acknowledged incorrectly the person making the signal shall repeat it until a correct acknowledgement is received. (2) When a signal is being acknowledged incorrectly the Diving Supervisor may decide to surface the diver to clarify the situation.

Particular care should be taken when diving in deep water and/or strong tides, to ensure the utmost clarity in transmission of signals is achieved. The ability to make and interpret signals in these conditions must remain largely a matter of experience.
