The NAUI Technical EANx Diver Course is taught over four days and consists of knowledge development sessions in the classroom as well as four open water dives on Nitrox. The course aims at teaching students on using nitrox mixes from 21-80% oxygen on dive no deeper than 40m (130 feet) that do not require stage decompression. The course is often taught in conjunction with the Decompression Techniques Diver Course.

The NAUI Extended Range Diver Course is designed at providing students with specialized training required to conduct dives to a maximum depth of 55m (180 feet), using air or nitrox for staged decompression. This course is conducted over six days and requires student's divers to complete six open water dives. This course is commonly combined with the Decompression Techniques Diver Course.

• Minimum Age – 21 Years Old
• Certification Level – NAUI Technical EANx Diver and Decompression Techniques Diver or equivalent
• Required Dives – 100 Logged Dives (30 of which need to be deeper than 30m/100feet)

The NAUI Technical Wreck Penetration Diver Course is designed to help divers combine their technical diving skills with deep wreck penetration. The course examines the skills and knowledge required by divers wishing to dive on wrecks deeper than 40m (130 feet). This intensive course takes place over six days and consists of knowledge development sessions in the classroom and eight open water dives.

• Minimum Age – 21 Years Old
• Certification Level – Penetration Wreck diver (with 10 penetration dives) plus
• Technical EANx diver and decompression Techniques or equivalent. Required Dives – 50 Logged Dives

The Trimix Diver Course consists of two levels, level 1 and level 2. These courses have been combined to give you all of the necessary knowledge and skills to enable you to utilize helium based gas mixes to conduct dives to a maximum depth of 75m (250 feet). The dives will require staged decompression using nitrox or oxygen as decompression gases.

This intensive course takes twelve days to complete and requires students to complete numerous knowledge development sessions, exams, as well as 14 open water dives.

Trimix diving involves a high level of mental and physical conditioning, please be aware that this can be a demanding course, but ultimately a hugely rewarding one.

• Minimum Age – 21 Years Old
• Certification Level – NAUI Technical EANx Diver and Decompression Techniques Diver or equivalent
• Required Dives – 250 Logged Dives (75 of which need to be deeper than 40m/130feet) and 10 of which must have been on best mix EANx, utilizing stage decompression techniques.

The NAUI Semi-Closed Rebreather Course teaches divers to be able to dive to a maximum of 30m (100 feet) using enriched air nitrox mixtures of between 32-80%. The course takes three days to complete and includes 4 open water dives. Your experienced instructor will train you in the analysis of your breathing gas mixes, buoyancy control skills, rescue scenarios on convulsing divers, hypoxia, flooded system and how to handle out of air situations, including the use of redundant air supply system. You and your instructor will also look at flushing the counter lung, ascents with reels and pre and post dive equipment checks. The course also involves come classroom work, with topics covered looking into physics, physiology, equipment, dive tables, narcosis depth, gas management and dive planning procedures.

• Minimum Age – 18 Years Old
• Certification Level – EANx Diver or equivalent Required Dives –50 Logged Dives (20 Nitrox Dives)

The NAUI Closed-Circuit Rebreather Course is a four day course consisting of knowledge development sessions and 6 open water dives on a rebreather unit. The course is designed to let the already trained nitrox diver learn the skills necessary to use a closed-circuit rebreather while using nitrox. The course is a no-stop decompression course, with a maximum depth limit set to 30m (100 feet).

• Minimum Age – 21 Years Old
• Certification Level – NAUI EANx Diver equivalent
• Required Dives – 50 Logged Dives (10 with Nitrox)
• Medical Certificate Required.

This is a great course for all technical divers and those interested in technical diving. This two day course teaches students how to prepare various mixed gases for diving, and the safety precautions and special equipment that is required to mix gases safely. During the course you will actually prepare a various gas mixtures in a safe controlled environment. This is course is often combined with other NAUI Tech course.
