Project Description

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

About The Course:


Buoyancy is often taught in Open Water and Advanced diver programs as a skill like regulator recoveries or mask clears when , in fact, buoyancy control is much more than that. Imagine teaching new drivers that maintaining speed is a skill that only needs to be performed during an evaluation or at a singular time, not any time the car is moving as it obviously is. Proper buoyancy control is like learning to drive, riding a bike or skiing. It is the state of being that divers should strive to master the entire time underwater. Mastering buoyancy as an ability is paramount for divers interested in wreck or cave diving, underwater photography or videography, technical diving or divers who just want to feel more in control. Even though this concept is trained at many levels there are just so many aspects to focus on that it seems to never get the full attention it deserves. The ECD Perfect Buoyancy Course will take you through refined proper weighting procedures, our ECD-specific instincts and habits, equipment considerations, trim, proper breathing techniques and the disadvantages of being over-weighted. Not to mention the in water actions and form that lead to dead-on accurate buoyancy control that can be applied during all phases of a dive. This program is perfect for those who feel like they are just working too hard underwater or those who feel like their weight system is just too heavy! Consisting of 1 session in the class, 1 session in the pool, and an optional free follow up play session, you’ll be surprised how much more control you have while diving.

Before Class

Before your Perfect Buoyancy Course, there is a bit of paperwork you’ll have to fill out. This program requires a minimum of 5 distinct forms. You can find the forms below and complete them ahead of your pool session, most important is the “SCUBA – MEDICAL FORM“. Go through the medical form 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 water. The doctors’ note is in the additional “PHYSICIAN’S RELEASE” file – along with guidelines for your physician. Remember if you answer “YES” to anything in the medical it is NECESSARY to get a doctors’ note BEFORE getting in the water. It’s also important to note if a physician’s signature is required, only a medical doctor’s (MD) signature will be accepted.






Additional forms as required:



Below to you can find an up to date schedule with all of our available PERFECT BUOYANCY class & pool sessions. Just remember you need to sign up at LEAST two days in ADVANCE. For convenience everything is done on the same day, just find out when we’re offering the course and sign up in-person, over the phone or via email!


The class training will take place at:

East Coast Divers, 213 Boylston Street, Brookline MA


and the pool training is located at the:

Private Courses

Private courses are set up slightly differently than regular Perfect Buoyancy 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 sessions scheduled – we can even schedule your pool training outside our normal pool hours*. Make sure to let us know in advance, as we have to rent the pool and make sure it doesn’t conflict with any other activities going on that day. If you do use the pool when we have it rented that’s perfect! There will be other people in the pool but you (or your group) will be working privately with your instructor.

*Additional fees (such as pool rental fees) may apply

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.

Students are required to own their own mask, fins, snorkel, and booties (if needed for the fins). These basic pieces of equipment should be personally fit to you and your body type. This will create the most enjoyable and productive training experience. If you already own your own and are unsure about fit or are borrowing from a friend we’d be happy to check the fit at the shop for free. We also personally fit many of our students to their own properly fit gear and keep many different sizes, styles, and prices in stock.

If you are interested in purchasing any of your own gear, we have everything you will need available in the shop! Stop by to meet with one of our product specialists for a personal fitting!
