We opened our doors in 1986 and have never looked back! Located on the North Shore of MA, we are smack in the middle of all of the best dive sites around. Head up to Rockport or Gloucester or out towards Marblehead and Nahant. We are a full service scuba and snorkeling center that will provide you with a wide range of PADI classes, a full repair and service center, local diving groups, dive travel adventures and of course a full compliment of rental gear and equipment sales.

Not only do we bring you the best service and knowledge, we bring fun and excitement. We are a group of fun loving people who love the ocean, underwater photography and traveling. We love to geek out about new gear and love to meet new people. Whether you are a new diver interested in starting your exploration of the big blue or a seasoned diver with years of experience we have what you need.

Evelyn Borish-wayson 5 star “I can’t say enough good things……..Shaun who was our instructor is my hero…….he really went the extra mile for a nervous slightly kooky student…ME! The shop is the best, knowledgeable and pleasant!! You’d be crazy to go anywhere else!”

Ryan Robbins 5 star  Great shop! Super friendly people who know and remember your name! I got my Open Water Diver cert from these folks. Larry & Shawn were awesome instructors. Bob, Whitney, & staff have been enormously helpful with gear questions, shopping, and answering my 50 questions. Looking forward to meeting new friends and diving with UD for years to come!”
