Combined Intro to Tech & Advanced Nitrox

Course Price: $1,900.00
Now Due: $950.00

 

This is a course specifically designed for recreational divers who want to become technical divers but have little to no experience using twin cylinders with a backplate and wing. In this 4-day class, we will spend the entire first day in the classroom, focusing on equipment in the morning and Advanced Nitrox academics in the afternoon. By the time we hit the water in the morning on Day Two, student divers are comfortable and confident. After our morning dives we break for lunch, and head to the classroom for debrief and academics. Day Three we again have our morning dive, followed by academics in the afternoon.

Day Four is our Weather Makeup Dive Day. If we lost a dive to weather, we make it up here, or we venture out for another Training Dive. After diving, we head to the classroom for a debrief.

Student divers who compete the class, will receive TDI certifications for both TDI Advanced Nitrox and TDI Intro to Technical Diving. Divers looking to venture further into technical diving will meet the certification prerequisites for the TDI Decompression Procedures, or Helitrox Diver courses.

Description

This is an intensive 3 day, 4 dive technical Scuba diving class that combines  training for two TDI certifications, Intro to Technical Diving and Advanced Nitrox.

In preparation for class, student divers will have to complete both the Advanced Nitrox and the Intro To Tech, TDI Online training courses and exams. Students will also have to sign the TDI Training Liability releases, fill our a Medical Statement, and get DIver’s Insurance.

Class size is 2 to 4 student divers, and you will need to make a deposit to hold your seat in class. I will be instructing with a second instructor in the water should there be 4 divers. Our primary focus is on the safety of the student divers, and being able to provide the kind of supervision and attention to allow you to safely build your foundation in twin cylinders. Our Dives will be open ocean, no deco wreck dives with a maximum depth of 75 feet. On the wreck we will work on skills and getting student divers comfortable in the gear.

If you do not yet have all of your personal equipment, rental equipment is available. For some divers, this class is an opportunity to try different gear, and discover what will work for them without buying the wrong item multiple times? We want to help you avoid buying gear that you will not be happy with, or will not do what you want it to.   This class is very much hands on, so if you have questions before, during, or after class, I am available to help you in any way I can. 

Required Equipment

What you carry is important. You want what to have with you exactly what you will need and not be carrying any of the crap you will never use. Below is what you should have for class, however in class we will discuss other important considerations such as accessibility, rigging, and validation. The “how” your gear is set up is crucial.

  • Wetsuit/Dri Suit – Depending on the time of year, and personal preference, either a 3mm or a 5mm wetsuit or a Dri Suit. If you want to dive Dri, go for it, but the water is going to be cooler in the Spring, warmer in Summer & Fall.
  • Pockets – I have glued two pockets, one to each of the thighs on each of my wetsuits. One pocket is on the front thigh; the other is on the side of my thigh. Installation was easy, AquaSeal and a pocket. I put the top of the pocket about an inch above the crotch of the suit. The pockets are well made and last longer than the wetsuits. When you retire the old, tired wetsuit, you can transplant the old pocket to new fluffy wetsuit. I use pockets to carry my Backup Mask, Lost Line Spool, Jon Line, Wet Notes, and spare Double Dog. They also help hold my knives in place. I prefer the Zippered Pockets by Dive Rite, Apeks, or Mares. Most Dri Suits come with pockets, usually big Velcro ones, which I am not a fan. Some wetsuit divers, not me, like the Tech Shorts with the bigger pockets. If you need help let me know.You can see what I use, if you have any questions, and go from there.
  • Gloves – Simple hand protection is what you need and if you already have gloves, they will probably work best?  For warm water, I prefer simple Gardening gloves or cut-resistant gloves, like Dyneema. Wreck diving is a full contact sport, and we need to protect our hands.
  • Fins and Booties– Long blade Freediving fins are not suitable.  Open heel fins work best. I do not wear booties, I wear mid height Marine Assault boots, either Altama or Woobies, with Lycra Socks, and XXL size fins. They are made for salt water, they are real shoes, and they last literally for years.
  • Mask – A good mask that fits you is essential. When suiting up, I wear my mask under my hood. In other words, I put on my mask and then pull up my hood. This keeps the mask on my face and does not allow the strap to blow off on water entries or pop off if my mask gets bumped in tight spaces. I credit this concept to Steve Belinda. I carry a backup mask, but I also practice active prevention.
  • Cylinders – IMHO, back mounted double steel cylinders with a manifold are the best primary cylinder setup for Open Circuit deco wreck diving. Side mounts, or Twin K Valves will also work, but not as well. You can bring your own cylinders, or I will supply you with Twin Faber LP85’s, and an Aluminum 40cf deco cylinder, all included in tuition.
  •    Regulators
    • You will need a Primary and a Primary Backup regulator on your Bottom Gas supply. One of your second stage regulators needs to be on a “long” hose that is 6′ or more in length. If you do not already have a long hose, you can borrow one from me, for free. I prefer 6′ to anything longer, but some guys like 7’ or even 9’? My Left Reg is my Primary, but the internet says I am wrong?
    • You need a single SPG (or transmitter) connected to the first stage regulator for each gas supply. It is not necessary to have two SPG’s on your Bottom Gas with a manifold, but you can if you like? I have an SPG, and an AI transponder on my Back Gas.
    • You will need a “Necklace” or some other way to hold your backup second stage regulator in place around your neck. I prefer using simple 3/16″ bungee and not the rubbery, store-bought ones where the regulator keeps falling out. A bungee necklace just works better. If you need one, I can make it for you.
  • Wing – You need a BCD suitable for the Open Water environment with your setup. A typical Wing will have 45# to 65# of lift, and IMHO 45# is ideal for most wreck divers who are weighted properly. The 45# wings, are generally narrower than the 60# wing. This means your profile for navigating restrictions is wider with the larger 60# wing. I like the Dive Rite Rec Wing in 45# with single or dual bladders because the bungees give me a nice narrow profile, and great trim. For deeper dives, divers really need an alternate ascent plan, in the event of a Wing Failure. Your best options are going to be Drysuit, dual bladder wing, or dedicated SMB/Lift Bag, in that order. If you have a dual bladder wing, do not have it connected to an inflator hose, ready to inflate. You are more likely to have an inflator issue, than a wing issue.
  • Backplate – You need a backplate with straps or harness. Backplates come in Stainless Steel and Aluminum. Stainless is heavier, and to reduce weight some have cutouts. In general, Drysuit divers want heavier plates, and Wetsuit divers want lighter plates, with Steel cylinders. If I am diving Aluminum 80 doubles, I use a stainless back plate for the weighting, so I don’t need additional weight. Brand is not so important. I personally prefer a continuous Strap over a sewn Harness for a variety of reasons. I also cross the straps behind my neck, right shoulder to left waist, and left shoulder to right waist. It better holds the cylinders in place and keeps them from moving around.
  • Dive Computer – A dive computer is essential. If you want to continue your technical diver journey, I highly recommend a Shearwater, and I will probably convince you in class.
  • Lights– One Primary light is required. I would suggest 1000 lumens minimum.I prefer on/off buttons to twisty turny. For wreck diving, Cannister Lights are unnecessary.
  • Jon Line – I will supply you with a high-quality Jon Line, you supply the Bolt Snap. It will be the finest Jon Line money can buy. Feel free to bring your own Jon Line, if you like, but the one I give you will be much better!
  • Weight – In theory, you will not need any weight if you are diving wet? Either way, I will get you weight if you need it. If you are diving dry, bring a belt or harness, and we have weight.

You are free to bring anything else you would like, other than cameras or scooters, as they are distracting.  If you have any equipment questions, which you will, just ask. My job is to help you. You will undoubtedly want to change some stuff around, but you do not have to change everything on Day One, or even before the end of class.
