The development of a telemetry and position indicating system for a diver

In a diving expedition safety is important both to the personnel on board the support boat and the divers. A diver needs to know their bearing and range to the support boat as diving progress to navigate freely in the water and to return to the boat immediately in time of emergency or after completi...

A diver needs to know their bearing and range to the support boat as diving progress to navigate freely in the water and to return to the boat immediately in time of emergency or after completing a task.
