During wall dives, what is an important aspect to monitor?

Monitoring depth during wall dives is crucial for several reasons. Firstly, as divers explore walls, they often encounter varying depths which can significantly affect buoyancy and nitrogen absorption rates due to pressure changes. Staying aware of the depth helps divers manage their ascent rate and prevent decompression sickness by adhering to safe limits.

Additionally, depth awareness aids in navigation and maximizes the diver's experience by ensuring they remain within the planned dive profile. It also allows divers to monitor their air supply effectively since deeper dives can lead to quicker air usage.

While factors like current strength, wall texture, and air temperature can be relevant in particular situations, they do not have the same direct implications for safety and dive planning as monitoring depth does. Understanding depth is fundamental to safe diving practices and enhances the overall dive experience.
