Come and pick me up (HELP)

Come and pick me up (HELP)

Scuba diving signals
This signal does not represent an emergency but we want to locate near the image above to indicate the difference between the two. This image means “pick me up ” and is done for someone on a boat to pick you up but does not involve any emergency or danger. The difference between them is the movement. With movement it means danger, motionless means no danger. But yes, if are in one of those situations that you need help your own common sense will be able to show whether there is danger, but it is worth to point it.
