You'll Dive Better
With Underwater World
Learn to scuba dive, find gear that fits and travel with people who love being underwater. Based in Horsham, Pennsylvania, we’ve been helping Philadelphia-area divers since 1973.
We love this store and the community of divers we have met through it!
Training & Certifications
Take your first breaths underwater with instructors who get to know you. Small classes and a high ratio of Dive Professionals to students mean personal attention as you learn, practice and build confidence.
We teach thinking divers. You’ll learn why each skill matters and show you can apply it in the water. When your course includes video feedback, you can see your technique and work through it with your instructor.
DIVE VACATIONS
Pick a place you’ve always wanted to dive. We’ll explain the diving, what’s included and what costs extra before you book. Your UWW trip leader keeps you informed, coordinates the group while you’re away and makes you feel welcome from the start.
Travel with us to Bonaire, Little Cayman and the Bahamas, or explore Fiji, Yap, Truk Lagoon, Palau, the Philippines, Iceland, Malta, Oman and Japan.
EQUIPMENT SALES & RENTAL
Come in, try things on and tell us where you’ll be diving. We’ll explain your options and check the fit with you. You’ll get advice without sales pressure, whether you need prescription mask lenses, a snorkeling set or a full scuba setup.
Try your new gear in the water and see how it feels. Our 30-day return policy allows reasonable use. Our Best Price Guarantee matches a current price for the same product from an authorized seller.
A special shout out to Nancy Fisher our Underwater World trip Planner/Coordinator who tirelessly worked behind the scenes orchestrating our travel and itinerary that went seamlessly

SERVICE & REPAIRS
Leave your gear with people who’ll explain what it needs and why. We keep you informed about the work and get your approval before going beyond your estimate.
We follow current manufacturer instructions and replace the parts required for your service. If we aren’t certified for your brand, we arrange the work with a certified partner. If a repair isn’t possible, we’ll talk through replacement options with you.
We had our equipment serviced before we left and everything worked perfectly.
