Project Description

We are Boston’s premier diving education center for High-Pressure Cylinder Inspection (VIP) & O2 Cleaning Classes and other scuba lessons in Massachusetts and New England!

About The Course:


Become a high-pressure cylinder inspector today! The International Training Visual Inspection Procedures program allows a VIP Inspector candidate to learn about and practice the techniques to effectively inspect a compressed gas cylinder for safe use. During the program, along with visual inspections, we also cover the cylinder filling process from the compressor to the fill whips. PLUS we also include a full module on Oxygen cleaning for cylinders, regulators and all other equipment that requires preparation for use with high O2 concentrations. 

The TDI Oxygen (O2) Equipment Service Technician Course allows candidates the ability to engage in the preparation of scuba equipment for the use and exposure of oxygen and other mixed gasses used in technical diving. The objective of this course is to train candidates in the proper procedures required for oxygen equipment cleaning.

Before Class

Note- All the paperwork you’ll need, along with a what to do before class checklist is located in the corresponding tab

Before you can start class you’ll need to fill out some paperwork. Most of this can be done ahead of time, but some of it will have to be done in the shop. The only piece that MUST be completed at the shop is a folder provided by SSI. You will need to fill this particular folder out in the shop as we keep it for our records. You can do this before class – just remember to show up 30 minutes early if you haven’t filled it out yet!

Risk Awareness Videos

There are a couple of forms that can be done ahead of time. Most important is the medical. Go through the medical now and check to see if you need to answer “YES” to any of the questions. If so no big deal – you’ll just need to get a doctors’ sign-off before we can let you in the pool. The doctors’ note is in the same file as the medical – Just scroll down to the next page. Remember IF you answer “YES” to anything in the medical it is COMPULSORY to get a doctors’ note BEFORE getting in the pool.



The Advanced Nitrox course is very intensive and includes 8 open water dives Check out the schedule and make sure you can attend everything in advance!
