For deeper or more complex dives, standard equipment is supplemented with redundant systems:
: 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. For deeper or more complex dives, standard equipment
: 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. the surrounding pressure increases
