Welcome to Northeast Scuba!



Renovation work is currently underway at Northeast Scuba and we hope to have the store back to normal by late April. The store is open during renovation, so if you don’t mind a little clutter here and there and maybe waiting as we find the item you are looking for, please stop in. We are open during this renovation with the exception of March 26th to March 30th. We will be re-open March 31st normal store hours  and regular store hours the following weeks. Thanks for your patience.




More than 3/4’s of our earth is covered by water. We have fresh water lakes, ponds, rivers and streams. All you need is the ticket to begin exploring these wet wonderlands and you can earn that ticket by learning to dive through Northeast Scuba.

Northeast Scuba is a full service dive facility offering equipment sales, scuba instruction, repair services and travel. Conveniently located off of I-495 at Exit 34 in Chelmsford, Massachusetts, we serve scuba diving and snorkeling enthusiasts from the Boston metro area, Southern New Hampshire (Nashua and Salem) as well as surrounding towns.

Dive Travel:

Traveling with other divers is always an exciting and unique experience. Northeast Scuba typically offers two or more dive trips to exotic (i.e. warmer!) locations each year. Some of our past trips included Grand Cayman, Bonaire, Turks and Caicos, Palau, Trukk, Cozumel, Wakatobi, and Belize. Locally we have planned dive trips off Gloucester and Rockport and to the Thousand Island area of upstate New York and Canada, Eastport in Maine, Rhode Island (German u-boat) and many nearby dive sites. Check out our upcoming trip to Indonesia. We also have Cayman Brac as a destination for October 2017.

We will be in the Phillippines in 2019 and on the Arenui diving Komodo in 2020.Click on the highlighted Komodo for a great video of diving Komodo aboard the Arenui. Manta Ray video from Diving Komodo aboard the Arenui.

North Carolina wreck diving Sept. 8/9/10, 2017.

Local diving is quite varied in our New England waters and there is much to see. Many divers don’t realize we have a very diverse population of marine life, wreck diving sites as well as many opportunities for hunting/catching underwater. Northeast Scuba often uses several local charter services to schedule boat dives, hunting trips and general exploration.If diving on some of our deeper wrecks holds interest for you then you will find we have connections to those seldom visited sites. If you want to dive locally then we assist you with your diving plans.

Please stop in and talk to us about the exciting world of diving and how you can become a diver or if you already dive, how you might advance your diving skills and knowledge or use our services to improve your diving experience.

Pro-Snorkeling Course: $135.00

Includes training on a Full Face Snorkel Mask (and you get to keep the mask when the training is completed).

Full Face Snorkeling masks are taking over the snorkeling world. They make it easier to enjoy fish and reef watching by just lying in the water and breathing. The mask does not fog up, the snorkel is built in and best of all, the viewing area of the full face mask is larger than typical masks thus making your viewing area even great.

The Northeast Scuba Pro Snorkeling class provides you with not only the proper training for snorkeling and the use of the Full Face mask but it also includes the mask. AT the end of the course the mask you use during the pool training session is your’s to keep. That’s right, the class fee covers 2 hours training in the pool and the mask. You can’t get better than this! There is something better, we have added the SSI on-line training for Snorkeling at absolutely no additional charge. If fact, you will also have access to the Try Scuba program, the Free Diving program and the first 3 chapters of the SSI Open Water Diver course at no additional charge. We want to make sure your experience in the water is enjoyable, safe and possibly leads to other exciting ventures beneath the waves.
