Search pattern
There are plenty of search pattern, but the following ones are the common ones.
- Arc (Signalman stays on one point on the shore / anchored boat)
- Box (Signalman follows diver, but on the shore)
- Circle (Signalman stays on one point on the anchored boat)
Line signals
Line signals are only necessary without an audio connection between the recovery diver and the signalman, and as a backup plan if the audio connection fails. They are changeable, but should be defined between the recovery diver and the signalman before the dive.
Example
- 1 … Ok
- 2 … Left
- 3 … Right
