Diving beyond the recreational limit of 40 meters (130 feet) moves you into the realm of technical diving.
: A simple safety benchmark where your maximum depth (in feet) plus your bottom time (in minutes) should not exceed 120 for recreational limits. Essential "Deep" Gear Diving beyond the recreational limit of 40 meters
For deeper or more complex dives, standard equipment is supplemented with redundant systems: This requires more air for neutral buoyancy and
: As you descend, the surrounding pressure increases, causing the air in your lungs, wetsuit, and BCD to compress. This requires more air for neutral buoyancy and significantly increases air consumption. nitrogen becomes narcotic
: At significant depths, nitrogen becomes narcotic, often described as a "euphoric" or "peaceful" feeling that can impair judgment. Additionally, the risk of oxygen toxicity increases, especially when using enriched air like Nitrox 32% , which has a maximum operating depth of 121 feet.
