Purpose of PADI DSAT Tec 50 Course

PADI DSAT Tec 50 course expands the knowledge base of the PADI DSAT Tec 45 divers with an added emphasis on mission planning and execution.  Certified PADI DSAT Tec 50 divers are qualified to make multi stop decompression dives that employ up to two gases EANx and O2  for accelerated decompression.  The PADI DSAT Tec 50 diver will develop the knowledge and skill to use open circuit technical dives to 50 meters/165 feet.

  • 15 deeper than 100 FSW
  • Medical form signed by a physician


3-4 days of diving (pool/confined open water) and 2-3 academic sessions and 1-2 configuration sessions

Depth Levels

  • Dive one- 30 ft max depth
  • Dive two -80 ft max depth
  • Dive three-165 ft max depth
  • Dive four-165 ft max depth

Course overview

Use decompression software and dive computers to plan and make multi stop decompression dives with air and/or EANx and O2 no deeper than 145ft

Use two cylinders of decompression gas with one up to 100 percent oxygen to add conservatism to the required decompression.

Equipment Requirements

  • Each diver will be required to have a complete set of personal dive equipment, including:
  • Double cylinders with a minimum of 121L/70 cubic feet each, with isolator manifold Primary & secondary regulators for doubles or single with appropriate valve

  • Exposure protection (dry suit use requires prior dry suit diving experience)
  • Weight system (if needed)
  • Lights as necessary, including primary and backup
  • Jon line (for current diving environments)
  • Safety reel and lift bag or DSMB. A suitable DSMB has sufficient buoyancy to help steady a diver during deco
  • Inflatable signal tube, whistle and/or other visual and audible surface signaling device
  • (2) Slates, (1 wrist-type)
  • Compass
  • Z-knife and back-up cutting device
