Deep 40

with Hydronauts

DEFY GRAVITY

Deep 40 is a specialty course that certifies you to dive to 40 meters. The course develops the knowledge required to plan, prepare, and execute a deep dive by understanding and mitigating the risks. 

On its own, Deep 40 is a 4 dive, 2.5-day course. The course can, however, but can be combined with or shortened if you are already an Advanced, Explorer 30, or Advanced 35 diver. 

We recommend combining the Nitrox course with the Deep 40 specialty.

Step 1 -
Online Study

Begin your e-learning before you arrive!

Your training starts online where you will access all your RAID training manuals and quizzes. Contact us to get started with your e-learning!

Step 2 - Theory & Workshops

On arrival, you’ll meet your instructor who will review your pre-completed e-learning with you. They will also conduct a few workshops on equipment, physics, physiology, management, and safe diving practices to help reinforce your e-learning. You’ll then plan and prepare for your dives and/or some confined pool training time. 

 

Step 3 - Optional Pool Training

At Hydronauts, we hold a very high standard for training our divers.  Our training courses require divers to complete a few additional skills not required by other agencies so we may spend a bit of time in our Training Pool with you before your open water dives. 

Step 4 - Open Water Dives

Now it’s time to put what you’ve learned in theory, into practice. After your theory and possible pool training, you’ll head out on 4 open water dives over two days. Together with your instructor, you’ll plan and prepare for each dive, completing skills and exercises at varying depths.
