When YOU want to stay down longer, deeper & safer!

There comes a time when you find that you have mastered the basic and even advanced skills of scuba diving from taking classes and putting that knowledge to vast experiences underwater. Maybe you've had 30, 50 or even over 100 dives. Are you ready to go to the next level? And what is the next level?

How about a 100 foot dive for 40 minutes? 
But, how can you do that when the no decompression limit on air is 20 minutes?

Every dive is a decompression dive even when you are on air. We know that we absorb nitrogen every time we dive and off gas as we ascend. To avoid DCS, decompression sickness, it's a matter of how much nitrogen we have absorbed, and how quickly we ascend to the surface. If you are Nitrox (enriched air diver) certified, you know that it provides the additional benefit of being able to stay down longer and absorb less nitrogen than breathing air. But, you also know that most Nitrox mixes also carry limited safe depth ranges under 100 feet in most cases. In technical diving, you learn new skills and gain experience diving with an instructor using techniques and equipment to safely dive. You'll learn to conduct gas-switch extended no-decompression dives, decompression dives and accelerated decompression dives using air and enriched air. Further training can also extend your knowledge, experience and depth and time range capabilities by training in the use of trimix (helium, oxygen and nitrogen).

Where would you be diving to 100+ feet?
Here are just a few places we recommend:
  • Southern California -there are many Wrecks (boat and airplane) & Deep off shore reef dives 
  • Florida/East coast Wreck diving
  • Cave diving - also, requires extra training for caves
  • South Pacific - many wrecks and deep dives averaging depths could be 90' to 130'.
Are there other considerations?
Absolutely! Other pre-requisites are equipment, prior experience and physical fitness which are also key components of becoming a Technical Diver. Without a doubt the training and gear is far more expensive. But asked another way, if you want this educational experience and the ability to explore the underwater world in greater range, how much is that worth to you?

Additional equipment investment can include the following:
  • BCD wing style ((or with a back plate (steel or aluminum) harness)) with "D" Rings and either a single or double wing. A single wing is acceptable if student is in a drysuit as that will act as redundant lift;
  • 3+ Regulators - Primary and secondary regulators for the twinset (primary with a long hose); stage bottle regulator in O2 service
  • 3+ Tanks - various combinations of twin aluminum 80's or steel 100s or a single 95 or 100 high pressure tank with an "H" or "Y" valve and an aluminum 40 cleaned with DIN fittings as a stage bottle configured with swivel clips.
  • 2 timing devices and wrist slate, such as a wrist mounted dive (two gas) computer and watch as a backup.
  • Lift bags (2) 50 and 100 pounds;
  • Reels and finger spools;
  • Lights and knife;
  • Back up mask;
  • Everything needs to be O2 ready
  • Training materials
Every student should have Advanced Open Water with extensive deep diving experience or even better Rescue Diver and MFA certification and current DAN insurance and be strong swimmers. Part of the training includes being proficient on basic watermanship skills with all of the additional equipment.

Why not just get trained and equipped with a rebreather?
With a rebreather you get the added benefit of diving nearly bubble free which is great for photography or just seeing aquatic life up close and personal. Most rebreathers usually come in one of two forms: semi-closed rebreathers and closed-circuit rebreathers which basically follow the same principles of Technical diving. Some additional disadvantages are that they are generally much more expensive to purchase and require more discipline since they are more complex to operate and as such require additional training. There are also many more failure modes than open circuit, which is generally working or not! Traveling with equipment is even more burdensome and any repair or service support while traveling could be very limited.
