Decompression Procedures

John and Rich finding a comfortbale deco spot in Devil's EyeThere are many reasons to choose to do decompression dives and we’ll discuss some of the more common ones. For some it may be about the gathering of knowledge to make one a safer, better diver, for others it is the natural path due to the environments they wish to dive in, from beautiful, limestone caves to deeper, more challenging wrecks.

We will talk about the concept of the soft overhead, the inability to make a free ascent to the surface and how dive planning takes on an almost zealous aspect. Your diving will be taken to a whole new level, where you’ll be able to plan how much gas we’re using during different portions of the dive while encompassing the need for adequate gas reserves. It is highly recommended that you have your own oxygen analyzer, but I can provide one if needed. Upon successful completion of this course you will be certified to use varying mixtures of nitrox or pure oxygen to decompress, enabling you to conduct decompression dives safely. As with all cave and technical classes that I offer, please realize that participation in the class does not guarantee certification. Should you not end up with a certification, I will provide you with a list of areas that need more practice and I’m more than happy to assist you in working with these. 

The required text is the TDI Decompression Procedures book, which I can send out to you ahead of time, and while the only prerequisite is 25 logged dives, it is highly recommended that you have taken the Advanced Nitrox (which is very commonly combined with this course) which will greatly improve your knowledge of the decompression gases used in this course.  On another note, I highly recommend that if you’re considering taking this course and are not yet familiar with a technical diving rig such as doubles, harness and wings that you enroll in my Intro to Tech class which will introduce you to the basics of a technical set up and give you a head start on this entry-level technical class.

Equipment needs are primary cylinder(s), a decompression bottle, three regulators, a slate and a lift bag (minimum of 25lbs lift, with 50lbs recommended!) If you have any other questions regarding equipment, training, scheduling or just decompression diving in general, please feel free to contact me at rich@divecaves.com and generally I will respond back to you within twelve to twenty-four hours.
