Study Notes
Diving Safety and Buddy System
- A good diving buddy enhances the experience, is familiar with each other's gear, and assists in all aspects of diving.
- Maintaining physical contact and timing entry during surf is crucial for buddy teams.
Dive Planning
- Planning dives prevents accidents; it's essential to execute dives according to plan.
- When selecting a dive site, consider the purpose, difficulty, personal skills, and those of your buddy.
Dive Equipment and Techniques
- A dive computer tracks nitrogen absorption, helping divers stay within no-decompression limits.
- Use a compass for navigation by aligning it with the target object and adjusting as needed.
- Sharing a dive computer with a buddy is not permitted.
Safety Procedures
- In case of losing contact with a buddy, search for one minute, looking around before ascending normally.
- Perform a safety stop at 15 feet for 3-5 minutes on every dive to enhance safety.
Diving Physiology
- The No-decompression Limit is the maximum time allowed at a depth without needing a mandatory stop during ascent.
- Surface interval refers to the time spent out of the water between diving sessions.
- Residual nitrogen is the excess nitrogen remaining in the bloodstream and tissues post-dive, which affects subsequent dives.
Environmental Awareness
- Rip currents are created when water retreats through channels in sandbars and reefs after breaking waves.
Documentation
- The SSI Total Dive Log is vital for recording medical history, emergency info, and personal dive records, serving as a resource for future dives.
Ascent Guidelines
- The recommended maximum ascent rate to ensure safety is 30 feet per minute.
- Dive computers are crucial tools for logging information, monitoring dives, and assisting in safe ascent/descent practices.
