Extend Your Dive Time
This is nothing to do with cavemen, just something that helps to fill a gap in recreational training from RAID.
The brand new RAID Nitrox Plus Course is designed for recreational divers who wish to extend their underwater time and gain insights into technical diving. But without investing in tonnes of new kit.
What Will You Learn?
Nitrox Plus provides the essential knowledge and skills to help divers explore new depths while managing the benefits and considerations of nitrox use more effectively than ever. The plus is that this is a two cylinder course which provides the security of extra gas when your adventure takes you to the recreational limit of 40 metres/150 feet. This is also a great opportunity to learn the most efficient way to carry a second cylinder of bottom gas… a great strategy when diving beyond 30 metres/100 feet, or so!
This course focuses on using nitrox for dives with a maximum safety stop of 10 minutes and incorporates a conservative gradient factor to ensure safety.
Nitrox Plus kit configuration can be:
Single cylinder (with or without H or Y valve) of adequate capacity for the planned dive.
One standard primary regulator setup fitted with long hose including piston clip.
One low-pressure (LP) inflator hose for BCD and dry suit (if appropriate). LP connectors must be interchangeable.
One backup regulator with standard hose fitted with neck bungee.
One SPG with piston clip.
Stage cylinder holding suitable gas volume of bottom mix for planned dives.
Stage cylinder rigging kit.
Cylinder marking for MOD, Diver Name and Mix (labelled as per RAID cylinder marking standards).
Suitable DIN regulator with SPG on a short HP hose.
A recreational BCD that has capacity to carry a stage cylinder.
OR
Wing, plate and harness with single tank adaptor.
Personal dive computer.
Backup computer or depth dive timer.
Wetnotes or wrist slate or finger slate.
Primary SMB.
1 x reels or spools with adequate line length for the dive depth.
2 x cutting devices.
Backup Mask.
Light where appropriate.
Smartphone, tablet or laptop with decompression software (instructor must have, optional for students).
Access to an oxygen analyzer.

Course Sign Up
Nitrox Diver Standards (ISO-11107:2009)
- Use nitrox breathing gas with an oxygen percentage ranging from 22 percent to 40 percent.
- Plan dives within modified No Decompression units using a programable personal nitrox dive computer or by using dive planning software.
- Describe the hazards of handling high-oxygen gas mixtures, and the basic requirement for cleaning scuba gear for high-oxygen environments (i.e. mixes up to 40% oxygen)
- Calculate the Maximum Operating Depth of an analyzed nitrox breathing gas at a target depth between 6 meters/20 feet and 40 meters/130 feet and a partial pressure of oxygen between 1.0 and 1.6 bar.
- Understand the relationship between an oxygen partial pressure and NOAA time limits to determine oxygen CNS loading.
- List the signs and symptoms of Central Nervous System oxygen toxicity.
- Understand how to calibrate a simple oxygen analyzer and use it to measure O2 percentage in a cylinder of diving gas. To familiarize themselves with the standards procedures for gas analysis, students should use the Nitrox Virtual Analyzer powered by RAID App.
- Demonstrate how to properly label an analyzed diving cylinder.
