Built by experience.
Tested by the ocean.
Da Zappah was created by someone who understands the underwater environment firsthand.
U.S. Marine Corps veteran, US Coast Guard–licensed captain, scuba instructor and commercial diving professional Glenn Harrington developed Da Zappah after decades spent working above and below the surface. His goal was simple: create a dependable underwater signaling tool that produces a strong, distinctive sound without connecting to a diver’s air supply.
Real experience.
Purpose-built performance.
Da Zappah was created from decades of firsthand experience above and below the surface—not from theory.
