Multilevel Dive
Definition
A multilevel dive is a dive where different depths are visited sequentially, often maximizing bottom time using dive computers or tables.
More on Multilevel Dive
Unlike square profile dives (constant depth), multilevel dives take advantage of reduced nitrogen absorption at shallower depths. Divers start deep, then gradually ascend to higher levels. Modern dive computers track nitrogen loading in real-time, making multilevel dive planning easier and safer. It’s often used on wall dives or reef slopes, allowing for longer exploration while staying within no-decompression limits.
Frequently Asked Questions
They allow longer bottom time, especially when diving progressively shallower. They also match natural dive profiles over walls or sloping reefs.
It’s highly recommended. Dive computers automatically calculate nitrogen absorption and decompression limits across depth changes.
Use dive tables like the Wheel or recreational dive planners that account for staged depth changes and surface intervals.
Yes, with proper guidance and monitoring. Many guided dives naturally follow a multilevel profile without the diver realizing it.
Yes, but ensure oxygen exposure is managed across depths. Your computer must be set correctly for EANx.
