Finally! The size of the scuba diving industry. 2nd Edition: updated market data, more data & more accuracy in dive industry market statistics. Dive equipment, scuba certifications, and dive travel. USA, Europe, and worldwide. Dive industry market data is hard to find. Some scuba statistics are publicly available, but most financial and market information is hidden. We did an extensive search to identify available and reliable market and economic data sources on the scuba diving industry. We summarized it for you, and we analyzed it to determine the size of the scuba diving industry. In addition to our own Business of Diving Institute surveys, we reviewed data from numerous sources, including OIA, BEA, DEMA, SFIA, U.S. Census Bureau, TIV Germany, RSTC Europe, Scubapro, Mares, Beuchat, Aqua Lung, BWMG, Shearwater, and PADI. In addition to scuba diving, we also look at snorkeling, freediving, rebreather diving, and tech diving. These are the most official unofficial numbers for the scuba diving industry.
