While our offer of "free lessons with the purchase of tanks" expired in 1959, MSD continues to provide quality scuba education. Originally issuing "Brainerd Skindiving Supply" diver certification cards, MSD joined with the Professional Association of Diving Instructors (PADI) in 1966 - the year of their inception. PADI now certifies 70% of divers world-wide. Incidentally, MSD founder Bill Matthies with PADI instructor number 79, is the lowest numbered instructor still actively teaching. We have a very experienced and passionate staff of eight instructors and ten dive masters that look forward to helping you achieve your instructional and recreational goals. For your convenience many of the knowledge development portions of the following dive certification courses are offered in a traditional group classroom environment or online. Because of our nearness to the incredible diving opportunities provided by the Cuyuna State Recreational Area, MSD also offers a scuba referral program for those that may have taken their classroom and pool elsewhere.
