Our History of Diving Museum Mark V patch, emblematic of the rich heritage of underwater exploration, originated as a symbol of the Diving Museum in Islamorada, Florida, which opened its doors in 2005. The patch itself serves as a badge of honor for divers and enthusiasts, representing a commitment to preserving the stories of maritime adventure and innovation. Through exhibits that include historic diving gear, artifacts, and interactive displays, the museum honors the deep-sea explorers who have pushed the boundaries of human capability beneath the waves.
