What is the significance of conducting a depth check before a dive?

Conducting a depth check before a dive is vital for ensuring that the dive is within acceptable limits and that conditions are safe for proceeding. This process helps divers confirm that they are aware of the depths they will be reaching, allowing them to plan their dive appropriately and consider potential effects on their bodies, such as nitrogen absorption and the risk of decompression sickness.

By knowing the depth, divers can also assess if they are operating within the range of their training and experience, as well as any equipment limitations. This precaution is crucial because diving deeper than planned can lead to serious health risks and complications. Thus, performing a depth check helps ensure the overall safety and success of the dive, making it a fundamental practice in dive planning and execution.
