For deeper or more complex dives, standard equipment is supplemented with redundant systems:
Diving beyond the recreational limit of 40 meters (130 feet) moves you into the realm of technical diving. For deeper or more complex dives, standard equipment
: 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. : A simple safety benchmark where your maximum
: 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 the surrounding pressure increases
: 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.
