Why is a 'restart' check beneficial before diving?

The 'restart' check is crucial as it ensures all equipment is functional and properly set up before diving. This systematic review involves inspecting gear such as tanks, regulators, buoyancy control devices, and dive computers to make sure everything is operating correctly and that all settings are appropriate for the dive. Ensuring that equipment is in proper working order minimizes the risk of equipment failure underwater, which can lead to dangerous situations.

Confidence, while important, is secondary to the primary function of the 'restart' check. Identifying new dive routes is not typically related to equipment checks, and while taking time to relax is beneficial, it doesn’t address the critical safety aspects of confirming equipment readiness before entering the water. The focus is fundamentally on safety, which is achieved through a thorough assessment of all dive gear.
