What does submersible pressure gauge not provide information about?

The submersible pressure gauge is a crucial tool for divers, specifically designed to provide accurate readings of the air pressure remaining in the tank and to indicate the current depth underwater.

The gauge displays the current air pressure in the tank, which helps divers monitor their air consumption and plan their dives accordingly. It also indicates depth, as the pressure reading increases with depth due to the weight of the water above.

However, the submersible pressure gauge does not provide direct information about the remaining time underwater. This is because remaining time tends to depend on several variables such as depth, air consumption rate, and the diver's activity level. Though divers can estimate their remaining time based on the pressure gauge reading and their air consumption rate, the gauge itself does not calculate this directly. Thus, it is vital for divers to be aware of their own usage patterns in order to effectively manage dive duration.
