What should divers mentally rehearse before every dive?

Mentally rehearsing emergency ascent procedures before every dive is critical for enhancing a diver's safety and preparedness. This practice ensures that divers are familiar with the steps they must take in the event of an emergency, such as equipment failure, a medical issue, or an unexpected situation that requires an immediate ascent to the surface.

By visualizing these procedures, divers can reinforce their knowledge and confidence, making it easier to execute them under pressure. In high-stress situations, having a clear mental plan can significantly reduce panic and help divers respond quickly and effectively. This rehearsal also serves as a reminder to monitor their own physical condition and the environment around them, which is essential for safe diving.

In contrast, while normal diving techniques, relaxation techniques, and underwater navigation plans are all vital aspects of a successful dive, the urgency of emergency preparedness makes it essential to prioritize rehearsing emergency response measures.
