The generally accepted depth limit for air or Nitrox is 45 m/150 ft. Even at this, narcosis can be a serious problem. The solution is to add helium to the mix. This can all but eliminate the risks associated with narcosis — so much so that many divers start adding helium for any dive past 30 m/100 ft.
Normoxic Trimix is that in which the oxygen concentration is at least 18 percent. This eliminates the risks associated with hypoxic gas mixtures, which require the use of a travel gas in shallow water. You can use Normoxic Trimix as deep as 60 m/200 ft without exceeding a PO2 of 1.4 ATA.
If your goal is to take your diving to the next level, Trimix is the only safe and sane way to go.
Please note: Because the only north-Florida dive sites which offer the necessary depth for this training, you must be certified to the full Cave Diver level. Course prices do not include the cost of gas…and helium costs noticeably more than air or oxygen.

Choose your price
Know what you’re getting: Prices include instruction and eLearning fees. Bear in mind, the cost of eLearning, by itself, can be worth anywhere from $140 to $280 or more. Thus, a $640 course from us may actually cost the same as a $500 course from someone else if you have to pay for elearning separately.
Certification cards: We issue these only when earned. Simply taking part in a course does not guarantee certification. For cave courses, certification cards from multiple training agencies may be available. C-cards generally cost around $30 each, depending on agency. Your instructor can tell you more.

eLearning included at no extra charge
Computer-aided instruction is an integral part of nearly every course we teach. The Why? is simple: eLearning helps get our students in the water sooner and spend more time there. It’s why we include the cost of any applicable eLearning programs — usually a $140 value — in our courses at no extra charge. This translates directly into an extra day of in-water training. The value of that? Priceless.
