TDI decompression procedures course


– 3 Days Minimum – $250/day –

Sometimes we just want to go over the limits that others have set for us.  This applies to diving as much as in any other thing in life.  The  TDI Decompression Procedures course is designed to teach those divers who dare venture beyond the limits how to do so safely. This is the first level of technical diving.

Very few things in life suck as much as having to end a perfectly awesome dive simply because your NDL time ran out. During the TDI Decompression Procedures course in Playa del Carmen, you will learn to plan and safely execute dives that require decompression stops.  The dives are done to a maximum depth of 45 meters, an accelerated decompression gases ranging up to 100% oxygen.

Once you’re certified, a brand new world will open up for you, and you will be able to sign up for more technical courses like trimix and advanced wreck diving.

This course can be taken in combination with the TDI Advanced Nitrox Course.
