More than 7,000 diving industry professionals from over 60 countries are expected to fill the Ernest N. Morial Convention Center when DEMA Show marks its 50th anniversary November 3–6. The four-day trade-only convention is set to bring together more than 500 exhibiting companies showcasing diving equipment, underwater technology, training resources and travel destinations, turning downtown New Orleans into a temporary capital of the global dive world.
According to Biz New Orleans, the Diving Equipment & Marketing Association produces the gathering as a trade-only convention serving the global diving and water sports industries, meaning it's restricted to qualified industry professionals rather than the general public. The outlet's account notes this marks the second time the show has landed in New Orleans since 2023, and DEMA has already selected the city to host again in 2029.
A Half-Century Since Its Miami Beach Origins
DEMA Show began in 1977 as a small gathering of diving equipment manufacturers in Miami Beach, Florida, and has since expanded into an international marketplace spanning diving, water sports and adventure travel businesses, per the same outlet's account. DEMA itself, headquartered in San Diego, now represents more than 1,400 member businesses worldwide, having grown from its original focus on equipment manufacturers to include retailers, training organizations, travel businesses and other industry participants.
This year's edition will offer more than 250 educational sessions addressing business growth, retail operations, marketing, diving instruction, technology and industry trends, alongside networking opportunities meant to help businesses establish new relationships. DEMA reported that overall verified participation at its 2025 convention climbed roughly 20 percent compared with 2024, with verified attendee registration growing more than 29 percent and exhibiting company participation up more than 6 percent. DEMA Show 2025 drew more than 6,700 attendees and more than 500 exhibiting companies, and it was recognized in Trade Show Executive's 2025 Fastest 50.
Golden Anniversary Party at Mardi Gras World
The anniversary celebration is scheduled for November 5 from 6 to 9 p.m. at Mardi Gras World, featuring networking, entertainment and presentations recognizing five decades of industry development. Industry reporting by DiveNewswire notes the party will spotlight veteran dive operator Neal Watson — known in the industry as the “Dive God” — serving as the 2026 DEMA Show Hall of Fame Ambassador, a pioneer credited with helping build Bahamas shark diving and dive travel into mainstream pursuits.
DEMA has also layered in new programming for the 50th edition. Association updates published by DEMA describe a new $35 Friday-Only Pass designed to give dive instructors who can't attend the full week affordable access to instructor-focused seminars and the exhibit hall. Official event listings show the show also introduced an interactive Attendees' Choice Award for its Product Showcase, letting attendees cast mobile app votes on featured dive gear through November 6.
Safety Seminars and Industry Economics
Divers Alert Network will host specialized medical and technical seminars at this year's show covering liveaboard vessel safety tools, decompression stress, and operational case studies drawn from the Thai cave rescue. DAN operates a 24/7 emergency medical hotline, and its presence on the educational schedule is a notable draw for operators and instructors alike.
A July 2025 study published in Cell Reports Sustainability, co-authored by researchers at UC San Diego's Scripps Institution of Oceanography and detailed by Ocean Decade, estimated that scuba diving contributes $8.5 billion to $20.4 billion to the global economy annually while supporting up to 124,000 jobs across 170 countries. Separately, a market report published by GlobeNewswire in October estimated the global scuba diving equipment market at $1.9 billion in 2025, projecting growth to $2.2 billion by 2032 as hardware innovations and expanding female and youth participation drive sales.
New Orleans Cements Its Convention Calendar
For New Orleans, the show is one piece of a packed autumn convention lineup. New Orleans & Company has announced 14 major conventions and meetings scheduled between September and December, expected to attract at least 225,000 attendees combined. DEMA's choice to return the show in 2029, after a 2023 stop and this year's 50th anniversary edition, builds on a rotation that sends the convention to Orlando in 2027 and Las Vegas in 2028.
The Ernest N. Morial Convention Center itself has been bolstering its credentials as a host venue. Separately, reporting on the center's Aa3 credit rating from Moody's cited solid financial backing for ongoing facility renovations and capital improvements.
The show's arrival also lands amid a broader tourism boom for the state. Louisiana hosted 45 million visitors in 2025 who generated more than $19.5 billion in direct spending and supported 225,600 jobs statewide, according to tourism data highlighted in Hoodline's coverage of the Louisiana Travel Summit. With DEMA Show's return already locked in for 2029, New Orleans looks set to stay a fixture on the global diving industry's calendar for years to come.
