Advanced + Nitrox Diver

Five days is all it takes to get you two of the most important certifications any diver can have: Advanced Open Water and Nitrox.

  • Without your Advanced Diver card, there will be a lot of dives you won't be allowed to sign up for, and a lot of classes you won’t be allowed to take.
  • Without your Nitrox Diver card, you'll be limited on bottom time; forced to make shorter dives and wait longer surface intervals. And, when everyone else on the boat is diving Nitrox, you may even have difficulty finding buddies.

The 40 Fathom Grotto Advanced Diver program combines both these important courses into one, allowing you to complete them in just five days. You save time. You save money — and you get a head start on being the best diver possible.

Who can learn?
This program is open to certified divers who meet the following requirements:

  • Be at least 15 years of age (12-14 for Junior Divers).
  • Be certified to the Open Water level (or equivalent).
What is involved? This program involves self study, classroom discussion and six training dives. For the Nitrox portion of the course, students have the option of using a traditional textbook or on-line training (recommended).

Our First Aid/CPR course follows the latest standards for Cardiopulmonary Resuscitation (CPR) training. It also addresses important topics such as:

  • Automated External Defibrillation (AED).
  • Blood-Borne Pathogens.
  • Emergency Oxygen Administration.
  • First Aid for Aquatic Life Injuries.

Designed to help divers meet important prerequisites for Rescue Diver and leadership-level training, the subject matter is nonetheless valuable for anyone who works or plays in and around the water.

Who can learn? This program is open to any individual age 12 and older. Basic life support and first aid skills benefit anyone. Be aware, however, that some of the curriculum is diving specific (but nevertheless interesting, whether you dive or not).

What is involved? This program involves self study and a lot of hands-on practice on a meeting room or classroom floor. You won't get wet but by all means wear comfortable clothes, including sweat pants or jeans.

Enriched Air Nitrox Diver

Few things have revolutionized recreational diving in the past decade as much as the introduction of Enriched Air Nitrox (EANX). Nitrox is nothing more than the air you are breathing right now with some additional oxygen added to reduce the concentration of nitrogen. While the additional oxygen offers no benefit in and of itself (and can, in fact, pose additional risk at depth), breathing less nitrogen provides divers with several benefits. Among them:

  • You enjoy longer no-decompression limits especially on repetitive dives.
  • You reduce the risk of decompression sickness compared to making the same series of dives using air.
  • Further benefits may include improved gas consumption, reduced fatigue and an overall feeling of well being.
If you own a modern dive computer, odds are it is capable of tracking your exposure to both air and Nitrox. Isn't it time you started taking advantage of your computer's capabilities?

Who can learn? This program is open to certified divers who meet the following requirements:

  • Be at least 15 years of age
  • Be certified as an Open Water Diver level (or equivalent).

Ultimate Buoyancy Control

Short of remembering to breathe and equalize, there is no skill more critical to divers than controlling buoyancy and no skill more difficult to new divers to master. In an ideal world, no diver would ever need this course, as you simply wouldn't be able to get certified unless you could demonstrate adequate buoyancy skills.
Unfortunately, the average diver's buoyancy skills just plain suck.They're an embarrassment — and make divers a danger to themselves and the environment.
Why do so many divers have such poor buoyancy skills? There are several reasons:

  • Developing good buoyancy control skills takes time and practice, something absent from so many entry-level scuba courses these days.
  • Learning to control buoyancy also requires the opportunity to get out and dive, while frequently stopping, starting and changing depth. Unfortunately, for many new divers, their open-water training consists mostly of kneeling on the bottom, waiting impatiently for the opportunity to do yet another "skill." In fact, most entry-level training "dives" don't involve much in the way of actual diving. (No wonder so many new dives can't control buoyancy.(
  • Buoyancy control is poorly understood, even by those who should know better. For example, most entry-level texts state that a properly weighted diver should "float at eye level." That may be true if you are wearing a 7 mm, full-length wet suit. If you try the same thing in a 3 mm jumpsuit, shorty or dive skin, you most likely won't be able to get under water or stay under water.

Buoyancy Control Pyramid

  • Proper weighting is the very foundation of the Buoyancy Control Pyramid. Yet most new divers never get to experience what it is to be properly weighted. Too many instructors love to egregiously overweight students in the pool (“Helps keep ‘em down…), and don’t do much better in open water.

The 40 Fathom Grotto Ultimate Buoyancy Control course is based on our experience as cave divers, cave diving educators and Cave Diver Instructor Trainers, with literally thousands of cave dives under our belt. Why is this important?

Because, as diving experts will tell you, nobody can control buoyancy like a cave diver. With the cost of not controlling buoyancy being a deadly silt-out, cave divers have to practice "buoyancy control like your life depends on it."

We base our course on the Buoyancy Control Pyramid, starting with its foundation (proper weighting), and moving up through BC use and, the ultimate in buoyancy control, how you breathe. Along the way, you'll discover things you most likely weren't taught in your beginning scuba course, such as:

While pre-dive weight checks are an acceptable way to discover whether you are grossly overweighted or underweighted, they are not the ultimate check for proper weighting. That comes at the end of the dive, when you have between 500 to 1,000 psi left in your cylinder. At that point, if you are properly weighted, you will be able to hover, motionless, at safety-stop depth, with no air in your BC.

Ultimate Buoyancy Control is a course no diver should need (any more than they should need a Wetsuit Diver certification), but which, unfortunately, the majority of new divers do need. And it's only available one place: right here.

Who can learn?
This program is open to certified divers who meet the following requirements:

  • Be at least 15 years of age
  • Be certified to the Open Water level (or equivalent).

What is involved? This program involves self study, minimal classroom time and two training dives (and, when we say dives, we mean dives, not sitting on the bottom, impersonating a rock).
