(Yelp Review Seabrook) Maximum Scuba is awesome! They will do whatever it takes to help you during your certification class. I was having trouble with some of the skills in the pool and my instructor Jeff Gordon helped me until I felt completely comfortable. The staff does a great job making you feel at home and doesn’t try to pressure you to buy anything, instead they just share their knowledge with their customers. I signed up for my Advanced class because they are excellent instructors and give you the opportunity to have fun at the same time! this dive shop is 5 stars hands down.
