What should you trust when navigating during a dive?

When navigating during a dive, trusting the compass is essential for accurate orientation and direction. The compass provides a reliable reference point that allows divers to understand the cardinal directions, helping them to navigate effectively under water where visual cues may be limited or distorted. Unlike other divers' estimates, which can be influenced by personal judgment, or intuition that can sometimes lead divers off course, the compass offers a consistent tool that, when used correctly, can ensure divers stay on track to their designated dive sites or return safely to their entry point. Additionally, while a depth gauge is important for monitoring a diver's depth and ensuring safety during a dive, it does not offer navigational guidance. Therefore, the compass is the critical tool for effective underwater navigation.
