What is the purpose of the pneumofathometer in diving?

The purpose of the pneumofathometer in diving is to assess depth in real-time. This device measures the pressure exerted by the water column above the diver, which correlates directly to the depth. By monitoring this pressure, divers can obtain accurate and immediate readings of how deep they are underwater, which is crucial for planning dives, avoiding decompression sickness, and ensuring safety.

Real-time depth assessment helps divers make informed decisions throughout the dive, ensuring they operate within safe limits and adhere to necessary safety protocols. Understanding depth is also essential for managing buoyancy and controlling ascent rates, thereby reducing the risks associated with diving activities.

Other options, such as measuring water temperature, monitoring air supply, or securing the diver's helmet, serve different specific purposes that do not relate to the function of a pneumofathometer.
