During a dry suit dive, when should a diver check their valves?

Checking the valves before entering the water and during the ascent is essential for several reasons. First, performing a check before entering the water ensures that all equipment, including the dry suit valves, is functioning correctly. This precaution helps to prevent any potential issues that could arise later during the dive, such as water ingress that could compromise the diver's thermal protection and buoyancy.

Additionally, checking the valves during the ascent is just as critical. As divers ascend, they experience a decrease in pressure, which can affect how the dry suit functions. Ensuring that the valves are working properly during this phase helps manage buoyancy and prevent any unwanted water entry due to pressure changes. This two-step approach enhances the diver's safety and comfort throughout the dive, making it a recommended practice for anyone using a dry suit.
