Who knows the communications Protocol? Communication is a key survival tool, especially when scuba diving.
A surprising number of out of air incidents are caused or exacerbated by miscommunication between dive buddies. In the scenarios that we have come across the message just isn’t getting through when distressed (out of air) divers are signaling his/her dive buddy. The attempted signal is acknowledged, but the message isn’t being received.
In these incidents it is as though the recipient is not verifying or acknowledging what they believe the message to be. As a result, the intended receiver of the message proceeds on with whatever is in their head having never received the message.
We must remember that communication is a 2-way event. There is a communications protocol. The sender sends a message, the receiver should interpret the message and reply with their understanding. A message is only successfully transferred when the the original sender sends acknowledgement to the intended receiver that the message got through.
The Communications protocol for properly sending and receiving messages is as follows.
