PADI IDC Skills and Environment — Study Notes & Practice Questions

The Skills & Environment section of PADI dive theory covers five topics — tides, currents, waves and rip currents, altitude diving, and search & recovery and night diving — plus a dedicated practice question section to test your knowledge before the IDC exam.

Each topic has its own page with a video designed to be a comfortable length to watch in a single sitting. Take notes as you go, then read the written summary below the video to consolidate your understanding. Navigation blocks at the top and bottom of every page let you move between topics without coming back here.
