What does SPG stand for in diving terminology?

The term SPG in diving terminology stands for Submersible Pressure Gauge. This device is an essential tool for divers, as it measures the pressure of the gas in the scuba tank. Since the gauge is designed to be used underwater, it provides critical information about how much air is remaining during a dive, helping divers to manage their air consumption and ensuring their safety.

Understanding the functionality and importance of the Submersible Pressure Gauge is vital for any diver, especially those engaged in advanced courses, as it plays a significant role in dive planning and execution. Monitoring tank pressure effectively is crucial for avoiding potentially dangerous situations caused by running out of air while underwater.
