A list of ANDI Technical Diving Courses (Open Circuit) available from Bruce Konefe
ANDI Level One
SafeAir Diver – Basic nitrox course for beginners that will teach the student to dive with mixtures up to 40% enriched air oxygen.
SafeAir Diver Limitations: The ANDI SafeAir Diver can dive with SafeAir mixtures up to 40% with a certification depth limit of 30 msw / 100 fsw, using one main cylinder and one RBS in accordance with the No-Stop-Required Decompression Limits.
ANDI Level Two
Complete SafeAir User – This course could be described as a “Advanced Nitrox” course or a “Introductory to Technical Diving” Course. This course is the basis for all level 3 and above courses.
Complete SafeAir User Limitations: May use Nitrox mixtures of 22% to 50% to 40 m/130 fsw performing No-Decompression Stop-Required profiles with 2 cylinders and 2 gases.
ANDI Level Three
Technical SafeAir Diver– For those of you that want to enter the world of “Decompression” diving, this is the where it is all at. Learn to dive with double tanks, decompression cylinder and dive down to a depth of 40 Meters.
Technical SafeAir Diver Limitations: May use all Nitrox and Oxygen mixtures to 40 m (130 fsw) during decompression profiles limited to a max of 30 minutes deco-time and 9 m (30 fsw) max stop depth, using 3 cylinders and 3 gases. No hard overhead / penetration permitted.
Technical Trimix Diver– If things where a bit fuzzy on that 40 meter dive, try doing the TTM course which will help clear things up and restore your memory. Learn to use helium from here on out the deeper dives where Nitrogen Narcosis starts to become a problem.
Technical Tri-Mix Diver L3 Limitations: May use all SafeAir, Helium and Oxygen mixes to 50 m (165 fsw) during decompression profiles limited to a max of 45 minutes deco-time, using 3 cyls and 3 gases at a max of 3.2 PN2 and 1.45 PO2. No hard overhead / penetration permitted.

(extreme technical exploration at 200m)
ANDI Level Four
Extended Range Diver– If you like Exploration diving this course can really help you out getting the long bottom time you need. We will teach you to dive with unlimited decompression and unlimited tanks. This can help you get the extra time you really need.
Extended Range Diver L4 Limitations: May use SafeAir & Oxygen mixtures without limits on the decompression obligations, dive run-times, number of cylinders or equipment configurations at a maximum depth of 50 m/165 fsw or 4.5 ata PN2.
Intermediate/Normoxic Trimix Diver – IF you really want to go all out with your diving this has got to be the “Ultimate”. Here you will learn the advantages of diving with helium to help out with the narcosis problems and also the 02 problems. Using helium can extend your range of diving to those deep unexplored places that no one has ever been before. Depth of 60 meters!!! NO PROBLEM.
Intermediate/Normoxic Trimix Diver L4 Limitations: May use SafeAir, Helium and Oxygen mixes containing 21% Oxygen without limits on the decompression obligations. There is a unlimited Dive run times, number of cylinders or configurations to a depth of 60 m/200 fsw with a max of 3.6 PN2 and 1.45 PO2. No hard overhead / penetration.
ANDI Level Five
Advanced Trimix Diver L5 Limitations: Full trimix allows the use of hypoxic oxygen mixtures, Helium and with unlimited decompression obligations, dive run-times, number of cylinders or configurations. Attainable depths up to 100m are possible to experience depending on skill levels and the quality of technical support. No hard overhead or penetration.
Gas Blending – All of those special mixes you hear people talking about and diving with. You will learn how to properly mix oxygen mixtures and helium mixtures that are suitable for today’s mix gas diving. Get on the job training on how to use are gas blending compressor and booster pump.
Certified Gas Blender Limitations: May operate breathing gas production equipment approved for Air and mixed-gas breathing applications. Also, to produce breathing gas mixtures by means of approved procedures.
Service Technician – If you are the type that like to mess with equipment repair, this course is right up your alley. A lot of today’s equipment needs to be cleaned for use with high-pressure oxygen. We can show you how to clean regulator parts, tanks, first stages etc for use with those nitrox fills.
Certified SafeAir Technician Limitations: Certified to service and maintain equipment for Oxygen or Nitrox service in accordance with ANDIs Oxygen cleaning procedures, manufacturer guidelines and local regulations.
