An online SCUBA class is available for free from the Massachusetts Institute of Technology (MIT). The class consists of videos of SCUBA lectures and videos of in-water SCUBA techniques. (The Real Media Player software may be needed to watch these SCUBA class videos.)
To become a diver, you would need hands-on and in-water SCUBA training yourself. But this online class provides a good beginner’s intro to SCUBA or a refresher for those returning to SCUBA diving.
The class teacher is a certified SCUBA instructor and emphasizes that much of the class is drawn from his own extensive diving experience. The MIT SCUBA lecture topics include:
- SCUBA Intro (history, equalization, snorkels)
- Diving Physics A (tanks, regulators, gas laws, humidity, air consumption rate, hand signals)
- Diving Physics B (suits and weight belts, pressure, oxygen toxicity)
- SCUBA Planning (decompression, in/outgassing, dive tables)
- Advanced SCUBA (altitude diving, flying, diving computers, dive planning)
- The Ocean (rescues, compass, water flow, marine life)
