Technical & Rebreather

Where Grand Cayman's walls really begin

The famous dropoffs are just getting started at 100 feet. Explore depths few divers get to experience through Cayman's highest quality technical diving center. Decompression training on open circuit, rebreather, and trimix, with full gas-blending, CCR support and one of the Caribbean's most experienced technical instructor trainers.

Why Tec Divers Choose Indepth

Built by a tec diver, for tec divers

  • Led by Nat Robb. Nat's been tec diving Cayman's waters since the 1990s. He founded Indepth Watersports in 2010 to support his favorite hobby: seriously deep diving. Open Circuit, CCR, Trimix, Cave, and more - if it's technical, you'll find Nat diving it.
  • Quality Instruction. We're a 5 Star TDI Instructor Trainer Facility, with TDI Instructor Trainer Dan, TDI Instructors Nico and Kelly, and Tech Guides Ash and Rapha all on staff.
  • Full CCR support. Rebreather rentals, unit-specific training, Sofnolime, a full range of onboard and bailout tanks, and batteries and parts in stock. Plus guides who dive CCRs themselves.
  • Trimix blending station. A 5000psi booster for accurate mixes, helium and oxygen on hand, and custom blends by request.
  • World-class terrain. Incredible deep walls just minutes away from the dock or shore, dropping down to 4000+ feet.

"I will be back with my rebreather next year."

"I dived with the owner, Nat Robb, who is an extremely experienced CCR instructor… They can fully support rebreather diving and also have sufficient helium and oxygen… I would heartily recommend InDepth Watersports." - ScubaBoard technical trip report
