Why Technical Diving?....
Go deeper, stay longer, see things untouched, undisturbed and unseen by most recreational divers. See history unmoved from where it landed on the bottom of the ocean. Experience life in the oceans without the anxiety of a limited life support system. Dive self-sufficient, prepared for everything to fail, yet relaxed in your training that you are prepared to handle the failure before you even enter the water. Enter the underwater world with a team, trained as you are, prepared to take full advantage of the resources of the team to handle all the water can throw at you. Expect to go deep and stay long, experiencing the quiet of this underwater world in ways you never imagined you could. Bring back images and stories to be shared and told today and into future. Where will you go? Who will you tell? When will you start? How long will you stay?

“Go Deep, Stay Long, Experience the Quiet!!”

Solo Diver: Learn self sufficiency tailored to your current diving. Can you “bail out” if something goes wrong and still go home to talk about it. OR you’re a photographer and want to limit the bubbles in the water while you’re waiting for that coral polyp to come out for a close-up.

Nitrox: Technical Nitrox, prepares you for the next level of technical courses. Gives you the academic knowledge you need to under stand Nitrox, beyond how to load it into your computer. All the calculations and decision making processes as prerequisite to enroll in the Advanced Nitrox course.

Intro to Tech: Learn your basic technical diving skills before you start your Advanced Nitrox course. Buoyancy, trim, SMB skills, gas sharing, equipment configurations and equipment management . Be ready to excel through your Advanced Nitrox Course.

Advanced Nitrox: Learn extensive technical dive planning and the use of technical gases with up to 100% oxygen. Polish the diving skills you learned in the Intro to Tech course and prepare to plan and dive beyond the decompression limits in your next course, Decompression Procedures.

Decompression Procedures: Extend the range of your diving beyond the “No-decompression” limits. Apply all that you have learned this far. Understand the use of additional gases to shorten decompression times. Extensive gas planning both individually and as a team member, developing the skills needed to become a part of a technical team diving to new limits based on gas volumes and person gas consumption. For the first time go deeper than the recreational depth limits.

Trimix: Everything jumps to a new level with Trimix. Add a Normoxic mix of helium and reduce the narcosis you have come to know diving air. Manage your Narcosis with the gases you will carry and breath. Increase your maximum depth to well beyond the recreational limits. Master the management of multiple gases and the dive planning associated with much longer decompression dives. Begin to see the deeper world that has in the past been out of reach.

Advanced Trimix: Take all that you have learned to another level again. Graduate to Hypoxic Trimix gases that will allow you to plan and conduct dives to as deep as 330ft. Team diving at it’s best. Advanced Gas planning, equipment management, team management and the knowledge that you have the skills to begin training for those dives you thought about when you took your first technical diving course. Your gas consumption is down and all the equipment becomes the means to go and stay.
