Happy Dive is a PADI dive school in Frankfurt, Germany, offering two levels of try-dive (Discover Scuba Diving Basic and Premium, the latter counting toward a later Open Water course), the full PADI Open Water Diver certification with an alternative "Weltenbummler" referral package for finishing open-water dives abroad, and dedicated women-only dive courses. It also runs an equipment rental service with cleaning, disinfection and inspection for each loan, a regulator servicing workshop (ultrasonic cleaning, diaphragm and O-ring replacement, pressure testing) and a cylinder filling station.
