The objective of this course is to train divers in the benefits, hazards and proper procedures for utilizing EAN-21% through 100% oxygen for dives not requiring staged decompression to a depth of 40m. All of our training dives are conducted in sea conditions using hard boats.
The course is normally run over 3 days. The first day is dedicated to academics and the remaining two days are purely for diving. 4 training dives are required with a minimum accumulated bottom time of 100 minutes.
The course fee includes all Instructor expenses, TDI Advanced Nitrox Manual and TDI certification fees. If extra training dives are required a separate fee will be charged. Boat fees and gas fills are not included.
Together with TDI Decompression Procedures course the candidate would meet the pre-requisites for TDI Trimix course.
Candidate Pre-Requisites:
- Minimum age of 18
- Basic nitrox certification (any agency)
- Proof of 25 logged open water dives
Underwater Explorers also requires candidates to be familiar with the equipment they will be using during the course. For those who wish to do the course in a twin-set but have never used one … start by looking at the Intro-to-Twins programme.
Equipment Requirements:
- SMB & Reel and cutting tool
- Underwater slate or notepad
- Alternative second stage attached to a primary regulator or redundant scuba unit
- Exposure suit adequate for the open water environment (dry suit recommended)
- Cylinder and regulator properly labelled and cleaned as required for EAN mixtures
- Underwater Explorers is able to provide some of the required equipment for the duration of course free of charge (subject to availability).
Graduation Requirements:
- Demonstrate ability to hover at fixed position without moving hands or feet.
- Show good awareness of team members through communications, proximity and team oriented dive practices.
- Demonstrate ability to manage freeflow from primary regulator in controlled.
- Deploy SMB correctly while maintaining position in mid-water.
- Conduct appropriate safety stop while using SMB.
- Demonstrate ability to share back gas with buddy as both recipient and donor in mid-water
- Demonstrate correct body position (appropriate trim, such as horizontal / streamlined).
- Demonstrate correct stress analysis with self and team members.
- Calculate and log CNS loading for each dive including cumulative exposure where appropriate
- Demonstrate correct use of oxygen analyzer including optimal procedure for calibration.
- Demonstrate understanding of gas labeling.
- Demonstrate adherence to conventions regarding prep equipment for oxygen service.
