Project Description

We are Boston’s premier diving education center for Nitrox and other scuba lessons in Massachusetts and New England!

About The Course:


Nitrox is a mix of Oxygen and Nitrogen that is different than what is in air. Typically the difference is that there is more Oxygen in the Nitrox that divers use resulting in less Nitrogen. As certified divers know, Nitrogen is responsible for decompression sickness and limiting the amount in the gas we breath can result in SIGNIFICANTLY more time underwater for each dive.


Our Nitrox Course can be completed in one evening and prepares you for any scenario. Nitrox diving is growing in popularity among recreational divers. Come and learn why so many divers are changing their breathing mixtures even for dives to 40 ft. Take your Nitrox course from the first store to teach Nitrox in Massachusetts… EAST COAST DIVERS!

Before Class

Before your Nitrox Course, there is a bit of paperwork you’ll have to fill out. This program requires 3 distinct forms. You can find the forms below and complete them ahead of your class session. This is a classroom only course and does not need any medical or physician sign-offs given that there is no in-water training.





Below to you can find an up to date schedule with all of our available Nitrox Courses. Just remember you need to sign up at LEAST two days in ADVANCE though we often can accommodate late signups for classroom only programs such as this one. This course is often run in conjunction with the decompression and dive planning workshop. If you’re interested in taking both make sure you sign up for both! You can signup with the link in the righthand column, in-person, over the phone or via email.


The class training will take place at:

East Coast Divers, 213 Boylston Street, Brookline MA

Private Courses

The beginning process is the same – you’ll still be required to fill out the same paperwork but you won’t be tethered to our schedule. Instead, you can find out whenever works best for you and let us know so we can get the session scheduled.

Private Scheduling is done through Kim and Max in our training department at They will be in contact within 24 hours of any inquiries. If you need to contact us sooner please call us at 617-277-2217.
