 ANDI International (ANDI) is one of the world's fastest growing diver training
agencies. ANDI began by specializing in training programs for Enriched Air Nitrox
(SafeAir) diving. As a natural evolution from SafeAir®, ANDI developed training
programs for what has now become known as Technical diving and Closed
Circuit Rebreather systems. To meet the demands of international network
training facilities, in 1999 ANDI introduced a unique methodology for training
entry-level divers with the ANDI Open Water Sport Diver program.
Technical SafeAir Diver TSD - L3
This Level encompasses the first level of what has become known as "technical diving". In general, a more
experienced recreational diver is the student prerequisite. Three cylinders and three gas mixes are the task
loading limits unless otherwise specified. In addition the training is limited to 50m
Max. Course Depth: 50 m
Min. Course Depth: 30 m
Min. Dive Depth for Certification: 21 m
Max. Deco Run-time: 30 min
Max. PO2 Deco: 1.6 PO2

Bottom Gas Limits - Helium: non
Theory Time: 14 - 16 Hrs
Dives: 4
Min. Bottom Time: 80 min
Min. Run Time: 120 min
Equipment configuration limitations: 3 cylinders 3 gases
Prerequisites: CSU (complete Safe Air) +50 dives
Extended Range Diver ERD L4
This is still a 50-meter course; you will be using more equipment and more mixtures of gases. You will be
using double tanks with two different mixtures of decompression gasses. Decompression is unlimited. This
course has a minimum bottom time of 120 minutes and runtime of 240 minutes. Includes manuals,
certification and diploma. Tanks and equipment not included.
Max. Course Depth: 50 m
Min. Course Depth: 40 m
Min. Dive Depth for Certification: 30 m
Max. Deco Run-time: As required
Max. PO2 Deco: 1.6 PO2
Bottom Gas Limits - O2: 1.45 PO2
Bottom Gas Limits - N2: 4.5 PN2
Bottom Gas Limits – Helium: non
Theory Time: 6-8 Hrs
Dives: 4
Min. Bottom Time: 120 min
Min. Run Time: 240 min
Equipment configuration limitations: As required
Prerequisites: TSD+ 100 Dives
Intermediate Tri-Mix Diver ITM L5
This course allows you to dive to 60 meters using helium, nitrogen and oxygen mixtures. This allows us to
breathe a mixture that has less nitrogen narcosis allowing us to think more clearly. This course takes 5 days
to complete. Boat trips, certification and manual included in this price. Helium, tanks and equipment are not
included.
Max. Course Depth: 60m
Min. Course Depth: 50 m
Min. Dive Depth for Certification Credit: 40 m
Max. Deco Run-time: As Required
Max. PO2 Deco: 1.6 PO2
Bottom Gas Limits - O2: 1.45 PO2
Bottom Gas Limits - N2: 3.6 PN2
Bottom Gas Limits – Helium: 16% or more
Theory Time: 5 - 7 Hrs
Dives: 4
Min. Bottom Time: 75 min
Min. Run Time: 240 min
Equipment configuration limitations: As Required
Prerequisites: ERD+ 200 Dives
Tri-Mix Diver TMD L5
The depth limit for the Tri-mix course is 100 meters. You will learn the importance of using helium to avoid
oxygen toxicity and nitrogen narcosis. The same equipment will be used as in the Technical SafeAir Diver
and Extended Range course. Tanks, equipment and helium are not included. The helium costs of the
Instructors will be divided up between the students.
Max. Course Depth: 100 m
