Extended Range / Tec 50 course is the next step to advance your technical dive training and skills. In this course you will start diving with two decompression gases and dive to a max depth of 55m / 180ft in TDI and 50m / 165ft in PADI. You will be tested in the classroom with advanced dive planning, decompression theory, and emergency protocols. 

The course is 4 days, 2 of training and 2 deco dives. We have plenty of great sites for the final deco dives like the wreck of the Josie J, that sits at 180ft/55m to 200ft/61m Or the famous Hole in the Wall crack dive that goes to 333+ ft/100m.

Before you start you may choose TDI or PADI for certification.
