Sidemount_TDITwo separate courses are covered within this on-line program, the SDI Sidemount Diver course and the TDI Sidemount Diver course. Whether to take this course through Scuba Diving International (SDI) or Technical Diving International (TDI) will depend on your past training and experience, along with your future goals. If, for example, you have no prior technical diver training and experience, and you do not anticipate exceeding accepted sport diving limits, you will most likely take this course through SDI.

International Training VIP Inspector Elearning Course

International Training Visual Inspection Procedures

Become a high-pressure cylinder inspector today! The International Training Visual Inspection Procedures eLearning program allows a VIP Inspector candidate to complete much of the academic requirements of the course at their own pace and on their own time. This is the first step for an individual who wishes to learn to the skills necessary to complete visual inspections on high-pressure cylinders in compliance with OSHA regulations. You will have access to the information provided in this eLearning program indefinitely after your training has been completed.

The Visual Inspector Procedures Inspector course is a two step process:

  • Step one is to complete this self-study academic program. This program will acquaint you with the history, rules and regulations, potential risks, and safe handling of high-pressure cylinders. It will also review fill station operations, compressor use and maintenance as well as identifying fill pressures, hydrostatic test stamps, and special markings on cylinders. This on-line program will also cover elements of valve repair, O2 cleaning cylinders, and the basis for performing visual inspections on composite, steel and aluminium cylinders
  • Step two is to print out the on-line course completion certificate and your course progress report and meet with an active International Training Visual Inspection Procedures Instructor.  Your instructor will review questions and concepts that were missed throughout the course exams to ensure 100 percent re-mediation of the materials. Once that is completed, your instructor will demonstrate and then evaluate skills and tools necessary to determine if a cylinder can remain in service and be safely filled and used. Upon successful completion of the practical evaluation with an Instructor, registrations will be submitted for processing, and you will receive your VIP Inspector certification.

SDI Master Scuba Diver Course

Categories: Tags: , ,

The SDI Master Scuba Diver Development Program was created to make true master divers. The program requires a new open water diver to complete four SDI or TDI Specialities, the SDI Rescue Diver Course, and log 50 dives. SDI feels a diver will be a true master scuba diver after these steps accomplished.

If you have completed most of these requirements, then visit the SDI Master Scuba Diver Development Course page. This page will take you from a non diver to a Master Scuba Diver.

The requirements are as follow:

  • Open Water
  • 4 Specialities
  • Rescue Diver
  • 50 logged dives

Our course recommendations are:

  • SDI Open Water Course, which is 4 dives
  • SDI Advanced Adventure Course, which is 5 dives. Completing 4 of the speciality dives as complete SDI specialities (Deep, Navigation, Advanced Buoyancy and Boat are recommended) extra 4 dives from the specialities.
  • SDI Rescue Diver, which is classed as 2 dives
  • 35 shore or boat dives.

To complete the 35 extra dives, is not quick task. At Atlantic Scuba, we quite often go on shore dives around Cornwall. We also have our own boat, which goes out at least once a week, all year round. I the summer, our boat could be going out 7 days a week. The time it takes to complete the 35 dives depends on your availability and finances. Shore diving is relatively cheap, especially if you have your own equipment. Boat diving is more expensive but takes you to more interesting and exciting dive sites.

So, if you fancy becoming an SDI Master Scuba Diver, give us a call now.
