For deeper or more complex dives, standard equipment is supplemented with redundant systems:
: 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. For deeper or more complex dives, standard equipment
: 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. This requires more air for neutral buoyancy and
: 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 For deeper or more complex dives
Diving beyond the recreational limit of 40 meters (130 feet) moves you into the realm of technical diving.
