In the old days, dive profiles were calculated from the surface down to a maximum depth, then back to the surface. Now, dive computers continually analyze your depth - giving you more bottom time for going shallower and allowing you to maximize your dive time. If you'd like to understand more about dive computers and learn how you can use tools like the eRDPML to plan multilevel dives, then the Multilevel Diver Specialty course is for you.
You'll review decompression theory as it relates to multilevel diving and dive computer models, and plan multilevel dives using the eRDPML. During the first of your two multilevel dives, you'll plan and execute a two-level dive, and on the second dive, you'll complete a three-level scuba dive.
Besides your basic scuba equipment , you'll need a full face mask that fits you and works with a regulator. You also need to have an alternate air source. Your PADI Instructor or our friendly staff will suggest other gear as appropriate, such as a dry suit if diving in cold water.
