Ocean Diver training - OT4 - Dive planning
Module objectives
Having walked through what students can expect to happen on an open-water dive in the last session, this module looks in more detail at the basics of dive planning. It reinforces the need for decompression planning and gives practical advice for planning with tables and dive computers. Gas planning and gas toxicity are also covered.
Achievement targets At the end of this module, students should:
- Know how to manage nitrogen absorption and release to minimise the risk of decompression illness (DCI)
- Understand the terminology used in the BSAC decompression tables and how to use the tables to plan a single dive
- Know how to plan repeat dives with no mandatory decompression stops
- Know the monitoring equipment needed to dive a planned dive
- Understand the basic functions of dive computers and how they can be used for dive planning and diving
- Understand the fundamental differences between dive tables and dive computers and that neither tables nor dive computers are infallible
- Be aware of the effects of altitude on decompression planning
- Be aware of the effects of flying on decompression planning
- Reinforce their basic understanding of oxygen toxicity
- Reinforce the need for gas planning, the use of the rule of thirds to plan gas requirements, and the need to monitor gas on dives
