Meet Glenn Harrington.

Glenn Harrington is a United States Marine Corps veteran, experienced commercial diver, scuba instructor and the founder and inventor of Da Zappah. Based in Hawaiʻi, Glenn has spent more than 25 years scuba diving and more than 20 years working professionally in commercial diving and other ocean-based operations.

After decades of working above and below the surface, Glenn recognized the need for a dependable underwater signaling tool that could produce a strong, distinctive sound without connecting to a diver’s air supply. Drawing from his military background, professional diving experience and firsthand understanding of the challenges divers face underwater, he developed Da Zappah.

Da Zappah represents the culmination of Glenn’s experience, problem-solving ability and lifelong connection to the ocean. His mission is to bring divers a practical, durable and thoughtfully designed tool created by someone who truly understands the environment in which it will be used.
