Description

In this episode, we explore why calling a dive can be so difficult and why safety ultimately allows us to dive more. We discuss how small issues and stressors, combined with the sunk cost fallacy, can lead divers to push boundaries they wouldn’t normally cross. Drawing on personal experiences, we highlight the challenges of making safety-focused decisions and why they’re essential for long-term enjoyment of the sport. Safety may seem like a small loss in the moment, but it guarantees the chance for many more dives in the future. Listen in to learn how to balance risk and reward to keep diving safe and fun.
