Divers Can't Agree on Safe Depth for Air Diving—Here's Why

What is the Maximum Safe Depth to Dive on Air? This has to be one of the most debated topics in scuba diving: how deep is "too deep" before you need to use different gases - nitrox or trimix? In this video, I analyze the community consensus by breaking down hundreds of your comments and comparing them against the physiological realities of Deep Air Diving. While some divers boast about pushing limits, we explore the critical balance between experience and safety, looking at how Nitrogen Narcosis, gas density and PO2 impact decision-making at depth. I explain why I draw a hard line at a 50m depth limit for air diving and why switching to trimix or other mixed gases is the smarter choice for deeper wreck exploration. Whether you are a recreational diver curious about limits or a tech diver planning your next expedition, understanding these boundaries is key to safe exploration.
