What skills are required for Deep Diver Training Dive 1?
Students must complete the following skills:
- Buoyancy and Trim Check: Start with a buoyancy check at depth to understand how pressure affects buoyancy. Focus on fine-tuning trim and buoyancy control.
- Basic Navigation Skills: Practice basic underwater navigation skills at depth, using compass and/or natural navigation.
- Depth Acclimatisation: Gradually acclimate to the increased pressure and reduced light. This dive should be shallower than the subsequent ones, ideally around 20 to 25 metres.
- Colour Changes: Using a simple colour chart, observe the initial changes in colour perception at this relatively shallow depth, particularly noting the fading of reds and oranges.
- Air Management: Monitor air consumption, noting the difference in consumption rates at deeper depths.
- Monitor No-Decompression Limits
