My Deco Diver Course
My version of Decompression Diver Training meets all of the standards for the TDI Advanced Nitrox and the TDI Decompression Procedures certification courses. However, I like to go a little beyond the minimums and provide students with some additional training, experience, and insight that I feel is important for divers who are planning and executing decompression dives. Students who successfully complete this training should be able to competently plan and conduct dives with mandatory decompression up to a depth of 150 fsw.
This class is offered independently by me, in Pompano Beach, Florida. The course consists of three days of training, ideally with lecture and diving each day. There are 6 certification dives total, conducted two dives per day. Class size is limited to 4 students, and teach the class myself, sometimes with an assistant.
I want you to train you how to properly plan decompression dives, with allowance for contingencies. At the same time, equipment seems to be the thing that most students need individualized help with. To execute these dives, you need to have all of the equipment you need, it needs to be easily accessible, you need to know how to work it, and it needs to be streamlined, so equipment is a big part of this program as well. For some of our underwater skills, we will be utilizing the Blackout Mask.
The best ways to counter the intimidation of a mandatory decompression dive is through knowledge, preparation, and experience. This builds a foundation for justified confidence. In three days, we will not make you an expert decompression diver, but we try to provide you with the tools to continue to learn and acquire experience in decompression diving, beyond the constraints of the course.
As much as possible, all of the dives will be on shipwrecks. The first day of diving we will work on skills in relatively shallow water. On day 2, we will be making wreck dives in the 100' to 130' range. For the last day, we will be making wreck dives around 150'.
Students that complete the requirements of the program will receive the TDI Advanced Nitrox and TDI Decompression Procedures certifications. However, participation in the program is no guarantee of successful completion and getting a certification. Divers must earn their certification, by meeting all of the TDI requirements, including a written final exam.
There are two class texts, the TDI Advanced Nitrox, and TDI Decompression Procedures Manuals. It is a lot of reading. Student divers will be required to read the texts completely prior to the beginning of the class. I will mail or deliver the books to you as soon as you register for the class. Students will also be required to do some additional reading in preparation for the class
In addition to meeting all of the Prerequisites, students will be required to read and sign the TDI Liability Release, and complete the TDI Medical History Form. Some students may be required to required to have their physician sign off on their participation in the course, based on their medical history.
The summer weather is typically great in Florida, and that's why they call this the sunshine state, however there are bouts of bad weather, and even hurricanes. It is entirely possible that we could lose one or all of our dive days. If the advance weather forecast is undeniably terrible, as in the case of a hurricane, I will make a decision to cancel. If we lose dive days due to weather, I will make them up with you, on mutually agreed upon dates. If you are flying to Florida, you may want to consider travel insurance? DAN now offers travel insurance, and I recommend that you look into it. At the same time, the weather is the weather and we will try to do the best we can to get you to complete your dives. If you miss a dive, you have 12 months to complete the dives for the certification.
- Students must be at least 18 years of age.
- Students must be certified as an Advanced Open Water Diver
- Students must be certified as a Nitrox Diver.
- Students must show a minimum of fifty logged dives.
- Students must have dive accident insurance.
- Students must possess a level of physical and mental fitness suitable for the pressures of diving in the wreck environment, to a depth of 150 fsw.
As divers, we love our equipment!! Modern dive equipment enables us to do what we do. The class is a good opportunity for you to discuss equipment options and then make educated decisions about what might work best for you and the way you want to dive.
Bring the minimum required, bring what you have, and bring lots of questions, but I would suggest you hold off on most major new equipment purchases until after the class, or you speak with me.
Please feel free to get back to me at any time with questions.
- Double cylinders with a manifold are the best primary cylinder setup for deco diving. Side mounts, or Twin K Valves will also work. You will need cylinder(s) with volume(s) appropriate for dives planned to 150’, considering your individual SAC rate. Cylinders can be rented for this course in Florida.
- All cylinders are to be labeled according to TDI Standards, which means Nitrox cylinders need to be labeled for Nitrox.
- An O2 clean Deco Cylinder is required for the class, rigged to carry. Bring whatever size you want, but most students use aluminum 40's. Typically, I will utilize an AL72 for classes.
- I can arrange cylinder rentals if you wish.
- You will need a Primary and a Primary Backup regulator on your Bottom Gas supply.
- You will need an O2 clean deco gas regulator.
- You need a SPG connected to the first stage regulator, for each gas supply.
- You will need a "Necklace" or lanyard to hold your Backup Second Stage Regulator in place. I prefer a simple bungee necklace, as opposed to the rubbery store bought ones.
- You need a BCD suitable for the Open Water environment, for your particular cylinder setup. A typical "Wing" setup for doubles will have 40-65 pounds of lift, however IMHO you are better off with something in the 45# range, like the DiveRite Rec in 45# with the dual bladder. For deeper dives, you really need a dual bladder. Trying to respond to a Wing failure is time consuming, and we dont have time to screw around on deep dives. Divers using a single bladder BCD, need a plan for alternate ascent in the event of a catastrophic BCD failure. A dry suit, lift bag, or SMB is suitable, but you need to know how to use it, and practice using it.
- You need one Primary Dive Computer, or Bottom Timer and Depth Gauge combination, plus a back up means to measure depth and time, in the event of a failure. Regardless of your system, you should be intimately familiar with the operation of at least your primary computer. I recommend Shearwater.
- You will also need a means to plan your dives using your dive computer, Smart Phone, laptop, or tablet. Examples of popular dive planners are IDeco, Ultimate Planner, Baltic Planner, and Multi-Deco .
- You will need lights:
- One Primary Light.
- One Back Up Light.
- You will need to bring with you at least one Ascent Reel, or spool, with a minimum of 150' of line on it, with at least one SMB (4-6' long). I prefer open bottom SMB's that allow you to fill with your BCD. Bring everything you already own, but don't buy a bunch of new reels and SMB's.
- A Line Cutting Device is required, and it needs to be sharp.
- A usable underwater slate, wrist slate, or notebook, and a writing implement are required.
- Bring a spare double dog clip, for attaching accessories, but no gate clips.
- You need a wetsuit or drysuit, with hood, suitable for the water temps for the dates of the course. Feel free to call me for a better handle on water temps and further advice.
- You need gloves to protect your hands. You can use neoprene dive gloves if you like, but rubber coated garden gloves are adequate for the warm water environment as well. I prefer the Hammerhead Dyneema gloves, which are cut resistant.
- You need a comfortable mask, a backup mask with a way to carry it, and a pair of comfortable fins. If you need to wear lead weights, make sure you bring a belt or harness to hold them. The lead weight you can get here.
Prospective students who meet all of the requirements, may reserve a place in class with a $600 non-refundable down payment. If you have any doubts about your ability to participate in this class, please hold off until you are sure the class and the schedule will work for you. The balance of $600 is due on the first day of class. Checks, cash, credit cards, and PayPal are all accepted.
