Open Water Diver

Open Water Diver certification

Scuba diving is exciting, stimulating, peaceful, serene, and an adrenaline rush – all in one sport! You can do it in Tahiti; Iceland; Florida; Missouri; Indonesia; Bonaire; and many countless other places all over the world! Divers see bright colorful fish swarming a reef; sharks looming out of the blue; a seahorse the size of your smallest fingernail sitting on a piece of coral in plain sight; or a Mola Mola that looks like four children drew a different part!

To ensure a smooth process, we recommend that you first sign up for the Open Water Diver class before registering for the orientation. Here's how to begin your scuba diving journey:

  1. Visit our Scuba Scheduler to create a student record and select the desired class. You can conveniently register online and make the necessary payment for materials and the class. Once registered, you will receive access to your online student materials.

  2. We offer two options for the Open Water Diver class and pool sessions. The first option is our weekend schedule, which includes sessions on Friday night (6-9 p.m.), all day Saturday (9 a.m.-5 p.m.), and all day Sunday (9 a.m.-5 p.m.). If you have specific scheduling needs, we can accommodate them with a custom schedule that will be reflected in the pricing. Please contact us to discuss your preferences.

  3. After signing up for the Open Water Diver class, the next step is to attend an orientation. It is mandatory for all students to attend a one-hour orientation session designed to provide important guidance and answer any questions students may have before starting their training. The orientation does not include any in-water activities. Our orientations take place every Saturday from 10-11 a.m. To secure your spot, it is important to schedule the orientation in advance. You can schedule it through the Scuba Scheduler or call us at 303-399-2877 to arrange a custom time if needed.



Once you receive the SSI link to access your online student materials, you can begin your home study for the class. This allows you to complete the coursework at your own pace, dedicating most of your time with us to the underwater experience. Plan to allocate approximately six to eight hours for this process.

For the best online experience, please ensure:

  • You have an up-to-date internet browser (Google Chrome 29 or Mozilla Firefox 24) with Flash and Javascript enabled.
  • If you use internet security software, add to your trusted sites or follow the instructions in the user manual.
  • Turn off pop-up blockers for



Your training includes an academic review in the classroom and in-water skills development training in our indoor, heated, saltwater pool at Denver Divers. The majority of your time will be spent in the pool, gaining essential diving skills and confidence. At the end of the course, you will take a 50-question written exam. Please plan to dedicate approximately 16 hours to this process.


To obtain certification, you will need to complete a minimum of four open water certification dives under the direct supervision of a qualified instructor. These dives allow you to apply what you have learned during your academic and pool training in a real-world diving environment. You will gain practical experience and further enhance your skills.

If you have any questions or need further assistance, please don't hesitate to reach out. We're here to ensure your scuba diving journey is enjoyable and successful!

Nitrox Diver

Get SSI Nitrox Certified!

We believe the best next step to becoming a safe and confident diver is becoming certified as a Nitrox diver. Nitrox is a gas that contains a higher concentration of oxygen than the air we breathe. This allows the diver to stay down longer, and increase safety margins.

Since we strongly believe in the use of Nitrox as a beneficial part of your diving career, we would like to encourage you to get certified for Nitrox during your Open Water Diver course.

If you sign up for Nitrox at any point during your Open Water Diver certification process, you will receive $50 off the course!


"Thank you so much for teaching me about scuba! I had so much fun and I cannot wait to experience open water diving! It was a unique class and great experience." - Nora

"I can't say enough about this organization! I just completed my open water certification class and our instructors (Mark, Paul and Glenn) were friendly, knowledgeable, passionate and very helpful. They take the diving process (which can be stressful for some of us) at a very good pace and prepare you fully for going underwater and don't make you feel pressured to do anything you don't want to until you are 100% comfortable. They prepared our class very throughly for our written and practical tests. I have already recommended Denver Divers to my close friends who are interested in diving and would recommend this to anyone!" - David
