We are located in the MetroWest part of Massachusetts 32 miles southwest of Boston. MAISI, LLC is a NAUI Platinum Pro Dive Center, scuba diving training facility & retail storefront with a Class-E certified Air/Nitrox station. MAISI, LLC specializes in scuba diving training from Intro to Scuba through Instructor including public safety diving. MAISI, LLC employs certified, insured Instructors and Dive Masters. Our facilities house a training room, office, air compressor & fill station, tank inspection station, and retail store. We also perform routine maintenance and repair on all major brands of tanks, valves, regulators and BC’s. Our training classes are kept small for more direct, one-on-one training. Our open water check-out dives are performed at Ft. Wetherill RI, Wallum Lake, Webster Lake, Cape Ann, and Rockport, MA.
Our air station is powered by a MAKO BAM06H air compressor with an air filtration and water separation system. It meets Class E & Oxygen Compatible air purification requirements and has regular scheduled independent air sample testing with the results posted. We blend our Nitrox fills (up to 40%) using a Nitrox stick and 3 separate digital monitoring points. We also fill pure O2 rescue tanks, Helium, TriMix, Helitrox, fire/rescue SCBA tanks, and paint ball tanks. Our Oxygen is Aviation Grade, and our Helium is Grade 5 UHP.
Our repair station is equipped with state-of-the-art regulator testing and repair equipment. Our cylinder inspection and service area is equipped with an internal tank inspection camera, Eddy Current tester, tank tumbler, internal washer & dryer, ceramic media and a glass-bead refinishing chamber.
Our training pool has graduated depth and is maintained with Sustain® instead of chlorine for the protection of our students and equipment.
We are Shearwater, ScubaPro, MARES, XS Scuba, Fourth Element, HOG, and A+ Marine stocking dealer of scuba equipment. We are also an authorized dealer and service center for OTS & Interspiro full face masks. MAISI, LLC is a registered business with the Department of Revenue, the Commonwealth of Massachusetts, and the Town of Milford.
We support the MetroWest Dive Club (www.
mwdc.org/) and recommend that all divers join and attend their monthly meetings and weekly dive destinations. Joining a dive club is the best way to meet new divers, and learn about new changes in the diving industry.
