This is serious training, for serious diving. Not every diver is going to be capable of dives in the 300 foot range. My version of Deep Trimix Diver Training meets all of the standards for the TDI Advanced Trimix certification course. 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 deep open circuit Trimix dives. Students who successfully complete this training should be able to competently plan and conduct decompression dives on Trimix, up to the TDI depth limit of 330 fsw, under similar conditions, using similar equipment.
This class is offered independently by me in Pompano Beach, Florida, near my home. Assisting me will be my friend, and fellow Instructor, Howard Ehrenberg. The course consists of three days of training, ideally with lecture and diving each day. There are 4 certification dives total. The planned lecture morning/dive afternoon schedule may be rearranged to accommodate the best weather conditions.
This is a serious class. It is fun for me to teach, and a great experience for students, but this is the highest technical certification for Open Circuit scuba. Divers signing up for this course already need to be savvy, responsible, experienced divers. This is an intensive three day program where we cover a lot of diving theory, but we will also be making some deep, serious dives.
I expect that you come to this class already knowing how to dive. This is a serious class for serious students. What we will be doing is honing the skills that you already have, and filling in the gaps of your existing knowledge and experience. As a novice diver you knew nothing, and you knew it. As you gained experience, you probably thought you knew it all. As you acquired real knowledge, you realized how much there still is to know. This is where I expect the student’s mindset to be for this class. We all continue to learn, and approach the deep water with humility and full knowledge of our limitations.
All of the training dives will be on local area shipwrecks. The first day of diving we will make two air dives working on skills inthe 100′-150′ range. On day 2, we will be making a single dive in 250′ range. For the last day, we will be conducting a single dive on a wreck in the 300′ neighborhood.
Students that complete the requirements of the program will receive the TDI Advanced Trimix certification. However, participation in the program is no guarantee of successful completion and getting a certification card. Divers must earn their certification, by meeting all of the TDI requirements, including a written final exam.
The class text will be the TDI Trimix Manual. Student divers will be required to read the text 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 watch the YouTube video documentary on the Dave Shaw fatality, The Last Dive of Dave Shaw, in advance of the class. http://www.youtube.com/watch?v=mF4iFJ-G74o An analysis of this accident will be made during the lectures.
In addition to meeting all of the Prerequisites, students will be required to read and sign the TDI Liability Release, complete the TDI Medical Form, have a physician sign off on the TDI Medical Statement,and fill out the Diver Information Sheet for use in an emergency.
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 agreeable 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. These are serious dives, so both the weather and the diver have to be absolutely right for the dives to take place.
This class is not for everyone. The diving is serious, and dangerous. Students need to be responsible, serious, and committed to managing the very real risks associated with dives like these. Diving deep on Trimix is inherently dangerous, you need to be prepared, and you have been warned.
- Students must be at least 18 years of age.
- Students must be certified as an Extended Range or Entry Level TrimixDiver.
- Students must show a minimum of 150 logged dives, with 50 deeper than 100fsw.
- Students must have dive accident insurance.
- Students must possess a level of physical fitness and mental maturity suitable for the pressures of diving in the wreck environment to a depth of 330 fsw.
- I will only accept students for this class that I am familiar with, and I have personally been diving with.
At this level of diving, I expect you to already have most of what you need for this class. Bring the minimum required, bring what you have, and what you are familiar with. I may have some additional equipment for you to try and compare.
Please feel free to get back to me at any time with questions.
- Properly marked Double cylinders with a manifold are the only primary cylinder setup for deep diving. You will need cylinders with volumes appropriate for dives planned to 300’, considering your individual SAC rate. You will also need two single cylinders set up as side slung tanks. Cylinders can be rented for this course in Florida, if you like.
- You will need a Primary and a Backup regulator on your Bottom Mix Supply, with one long (6′) second stage regulator LP hose, and a necklace to hold your Backup second stage in place. You will need two deco gas regulators, with SPG, at least one O2 clean.
- You need a Buoyancy Compensator suitable for the Open Water environment, and your particular cylinder setup. A typical Wing setup for doubles will have 35-65 pounds of lift.
- 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.
- 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, and MV-Planner.
- You will need one Primary Light, and one Back Up Light.
- You will need to bring with you at least one Ascent Reel with a minimum of 300′ of line on it, and at least one SMB (6′) , and a backup SMB spool/reel.
- Two Line Cutting Devices are required, and they need to be sharp.
- A usable underwater slate, wrist slate, or notebook, and a writing implement are required.
- Bring two spare carabineers, or double dog clips, 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 work gloves are adequate for the warm water environment as well.
- You need a comfortable mask, and a comfortable pair of fins that fit you.
- 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.
The cost of the class is $1,200. This includes all of the training, the 4 boat dives (3 trips), the class text, and the Advanced Trimix certification from TDI. There are no additional class costs, however students are responsible for tips for the dive boat crew, cylinder rentals (if required), Trimix and Nitrox gas fills for the dives, and for maintaining their equipment in good working order. Of course, students will be responsible for all their own transportation, meal, and lodging costs.
Prospective studentswho 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 do not make a commitment to attend until you are sure the class fits you, and your schedule. The balance of $600 is due on the first day of class. Checks, cash, credit cards, and PayPal are all accepted.
