The last Advanced Nitrox/Decompression Procedures course of the summer will begin August 23-24, 2008.
This initial weekend should cover the bulk of the academic study and several dives. Remaining meetings will be scheduled after completion of the weekend’s activities.
This course is the entry level technical course in the line-up of TDI courses. Graduates will be proficient divers capable of planning and executing simple staged decompression dives using nitrox and oxygen to optimize decompression obligation. This combination course consists of approximately 8 hours of classroom work, at least three skills dives and at least 3 “working” dives.
Prerequisites: Candidates for this course should have experience diving in the conditions in which the course is to be conducted (e.g. Great Lakes). They should have a fundamental grasp of buoyancy and trim, and be familiar with the gear they will be wearing for the course. An advanced certification from SDI or another recognized agency and basic nitrox certification is required. The majority of candidates for this class wear a backplate, wing and double cylinders, but a single large-volume tank fitted with two first stages is acceptable. For a full equipment list, please ask.
Course fee is $850 per person and includes all textbooks, handouts, cards (upon successful completion of course objectives), and the instructor’s time and expenses.

It was back to Gilboa Quarry this past weekend for the initial weekend of an Advanced Nitrox/Decompression Procedures course. I met up with Brian, Ryan and Wally Saturday morning at the quarry. The plan was to do a few hours of academic material followed by our first training dive. We got off to a slow start due to an unexpected downpour just as we were getting ready to begin. We began an informal classroom session in the office until the rain let up. Marshall Allan brought down his nice new 8′ X 10′ enclosed trailer for us to use as a “portable classroom.” We set up chairs and a whiteboard inside and got down to business.
Around noon we took a break for lunch and then reconvened to get ready for our dive. We looked over each other’s equipment and configurations and planned our dive. We entered on the deep side of the quarry, swam over to a shallow shelf at about 30′ to do some manifold drills and gas sharing. Then we dropped down to the 70′ platform to work on deco cylinder handling, gas switches and SMB deployment.
Sunday morning we again met at 9 to do 2 more dives and just a little more classroom work. The first dive was another skill dive with “simulated” deco stops during the ascent. Our last dive of the day was a deep dive, incurring a small deco obligation, with the emphasis on proper execution of the dive rather than more skill repetition.
Other than some rain Saturday morning, the weather was sunny and hot, making for a beautiful weekend. Brian, Ryan and Wally all did well, although everyone knows what to put extra work on. Marshall was kind enough (or cruel enough) to video tape several of the class dives and give the guys DVD’s to take home so they can critique themselves. Video is a very valuable teaching tool and I appreciate Marshall bringing his camera and even his DVD duplicator out to the quarry for us.
This course will finish up with dives in the 1000 Islands in a few weeks. The St. Lawrence is one of my favorite dive sites, so look for a report around mid-August.
