PADI Full Face Mask Diver Course

My Experience with the OTS Guardian Full Face Mask

While taking my PADI Open Water course, I met a diver named Teo who was using an OTS Guardian full-face mask. He was already certified and diving with his daughter, who was completing her Open Water class. Teo shared all the benefits of the mask — no fogging, the ability to breathe through your nose, and overall comfort. It sounded fantastic to me!

Around the dive shop, several people also had the Guardian and spoke highly of it. The one recurring comment I heard, though, was that it can be harder to breathe below 60 feet. Still, curiosity got the better of me, and I decided to take the course to see for myself.

I first tried the mask at Lake Denton, staying around 25 feet deep. It felt surprisingly comfortable. Breathing felt natural, and being able to breathe through my nose was a definite plus. That experience convinced me to sign up for the PADI Full Face Mask Specialty Course to get properly certified.

We started training in the pool. After some practice, I was able to complete all the required skills. I later took the Guardian on my Advanced Open Water dives in Pompano, which gave me more real-world experience using it in open water.

What Makes the OTS Guardian Mask Stand Out

More Comfortable, Natural Breathing

Because it covers your entire face, you can breathe through both your nose and mouth. I’ve noticed this helps reduce jaw fatigue and makes for a more relaxed dive.

Excellent Seal and Fit

The double-skirt design features a soft, flexible silicone seal. It adapts well to a wide range of face shapes and sizes. It’s comfortable, helps prevent leaks, and even reduces outside noise.

Strong Field of View

The Guardian’s polycarbonate visor provides a wide, unobstructed field of vision. You can easily add accessories like a GoPro or light rail system for filming or exploration.

Anti-Fogging and CO₂ Management

The mask’s one-way valves and airflow system help prevent fogging and reduce CO₂ buildup. This makes longer dives more comfortable and safer, provided you manage your air consumption properly.

Ambient Breathing Valve (ABV)

A useful surface feature, the ABV allows you to breathe ambient air before the dive, conserving tank gas. Just remember to close it before descending!

Easy Maintenance and Modularity

The removable second stage makes cleaning and storage easier, especially after saltwater dives.

Communication Ready

The mask includes a port for communication systems, like the Buddy Phone. This is great for divers who want to chat underwater, especially for training, public safety, or commercial work — though the clarity can vary.

Added Warmth and Protection

A full-face seal helps keep cold water off your face and prevents water from entering your nose or eyes. It also keeps your mouth from drying out — a small but welcome comfort.

Things to Consider

Cost

This setup isn’t cheap. The OTS Guardian runs around $900 before adding accessories or taking the specialty course. It’s definitely an investment.

Training & Familiarization

It takes time to get comfortable with the mask. Clearing, equalizing, and handling emergencies all feel different. Proper instruction is essential.

Air Consumption

This was the biggest drawback for me. I noticed my gas use nearly doubled compared to a standard setup. Results will vary, but if maximizing bottom time is your goal, this is worth serious consideration.

Bulk and Weight

The mask adds bulk and buoyancy, which can make travel and gear management a bit more cumbersome.

Equalization

Since your nose is covered, you have to use the built-in nose block system to equalize. It works fine once you get used to it, but it takes some adjustment.

Final Thoughts

While I genuinely enjoy diving with my OTS Guardian, I’m still on the fence about whether the investment is worth it at my current skill level. For now, I plan to use it on future dives — especially on my upcoming trip to Venice, Florida, to hunt for Megalodon and shark teeth — and see where it truly shines.

At this stage in my diving journey, where I’m still focused on improving my SAC rate and extending my bottom time, the Guardian might not be the perfect fit yet. But as I gain more experience, I can definitely see the appeal — and I’m excited to keep experimenting with it.

Exploring the Ocean: A Journey of Discovery

Diving is more than just a hobby; it's a journey of discovery. Each dive offers new experiences and insights. The ocean is vast and full of wonders waiting to be explored. From vibrant coral reefs to mysterious shipwrecks, every dive tells a story.

The Importance of Community

Building a community around diving is essential. Sharing experiences and knowledge can enhance our understanding of the underwater world. It’s inspiring to connect with others who share the same passion. Whether through local dive shops or online forums, finding a supportive community can make a big difference.

Safety First

Safety should always be a priority when diving. Proper training and equipment are vital. The OTS Guardian mask is just one example of how technology can enhance our diving experience. Always remember to dive within your limits and respect the ocean.

The Future of Diving

As I continue my diving journey, I look forward to what the future holds. New technologies and techniques are constantly emerging. I’m eager to learn and grow as a diver. Who knows what adventures await beneath the waves?
