Thunder Bay Scuba is centrally located along Lake Huron's "Shipwreck Alley" just inside the City of Alpena. We train and supply divers needs from Tawas City in the south to Presque Isle to the north. The Dive Shop sells diving and snorkling gear from Oceanic, Bare, Scuba Max, & AmeriSea. Open 7 days a week from Memorial Day to Labor day, and 5 days a week the rest of the year. We offer Air and continous blend Nitrox fills. Working with charter operators we can book your dives and arrange accomodations for your group. We do our best to show your group a good time so when the weather blows your charter off the Lake ask us and we will arrange for alternate dives.
