Where should the diver's pneumofathometer be secured?

Securing the pneumofathometer at or near the diver's helmet is essential for ensuring accurate depth and pressure readings during a dive. The pneumofathometer is an instrument that measures the ambient pressure experienced by the diver, which is directly correlated to depth underwater.

Positioning the device close to the helmet allows for real-time monitoring of pressure changes experienced by the diver. This is crucial for assessing potential risks such as decompression sickness and ensuring safe ascent profiles. Additionally, having the pneumofathometer in proximity to the helmet minimizes the chance of lag in data transmission, which can occur if the instrument is situated too far away.

Conversely, securing it at the surface support station, on the diving vessel, or at the designated dive station does not provide the immediate access or accurate readings required as the diver descends, thereby compromising safety and operational efficiency during the dive.
