Do you want to increase your buoyancy control, minimize your breathing gas consumption, or move effortlessly above the ocean floor? The SSI Perfect Buoyancy program teaches you the skills and techniques needed to maximize your dive experience, increase your comfort in the water, and get the most from your equipment. The course focuses on the knowledge and skills needed to improve your diving position (trim) and buoyancy control, which should help you safely minimize breathing gas consumption. 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.

Why learn perfect buoyancy?

Buoyancy instruction during may diver certification programs is often taught as an individual skill, like regulator recoveries or mask clears are. At East Coast Divers, we believe buoyancy control is the foundation for comfortable and safe diving which is why all skill work in our programs is taught while students maintain neutral buoyancy. This level of training helps our students excel at diving as soon as they hit the open water and prepares them to handle challenging situations and advanced training. The ECD Perfect Buoyancy program will help you improve your diving comfort no matter what your level of experience. It 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 but mastering buoyancy as an ability is paramount for divers interested in wreck or cave diving, underwater photography or videography, technical diving.

Consisting of 1 workshop session in the classroom, 1 session at the pool, and an optional free follow up play session, you’ll be surprised how much more control you have while diving.

If you have questions that aren’t answered by the website you can always call (617) 277-2216 or shoot us an email at and we’ll help you get your buoyancy squared away!

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. Please contact us for pricing and sign-up information.

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!
