Tek Dive Guam

Big congratulations to Peter on completing IANTD’s RCCR Deep Diver course on his Hollis Prism2 rebreather! 🙌

After making the long journey from Salt Lake City, Utah, Peter jumped straight into an action-packed week of training—covering academics, detailed unit inspection, and mastering assembly and operational checklists. Once he shook off the jet lag, he logged over nine hours underwater, sharpening emergency skills, dialing in buoyancy control, and fully experiencing the advantages of rebreather diving.

Now he’s off to enjoy a well-earned dive adventure in Chuuk—safe travels and incredible dives ahead! 🌊

Thanks to TNT Divers Guam and Casey Shumway for joining me in a huge cleanup project after the storm. The photos don’t do it justice, but a ridiculous amount of boulders and “ankle breakers” were removed, both in the water and on shore, to make a safe entrance for our divers. It’s better now than ever before!

March was a busy one for CCR training!

First we kicked things off by teaming up with Dive Travel Guam for an incredible trip to Chuuk, diving the legendary wrecks with Blue Lagoon Dive Resort.

With gases blended and bailout bottles topped off, it was time to get to work on the deeper wrecks. Elliot put in serious reps, sharpening his skills throughout IANTD’s Normoxic Trimix course on his Liberty Sidemount CCR and returned to Guam fully certified! Congratulations 🎉

Then it was Casey’s turn to experience what rebreather diving is all about on his Hollis Prism2 CCR.

During his CCR Advanced EANx Diver course, he focused on the details that matter—dialing in his unit build, running consistent operational and pre-jump checklists, and developing the mindset to calmly and effectively handle problems if they arise. Congratulations 🎈

Please congratulate both Elliot and Casey for their outstanding performance during their demanding courses. Hand 👏 👏 👏

🚨 Last-Minute Class Opening! 🚨

I’ve got a spot open for an upcoming AN/DP course—grab it before it’s gone!

If you’re interested, shoot me a message for prerequisites and equipment requirements, and I’ll get back to you shortly.
Note: If you plan to take the course in sidemount configuration, you must already be sidemount certified. Oddly enough, that can be completed as well. 😃

🔥 Go Sidemount. Go XDeep. 🔥

As an official XDeep Ambassador, I’m proud to offer the full line of XDeep sidemount systems — and the training to match.

Whether you’re:
• Looking to improve trim and buoyancy
• Wanting redundancy and flexibility
• Transitioning into tech
• Or just ready to dive smarter and more streamlined

Sidemount changes the game.

I offer:
✅ XDeep sidemount systems & configuration support
✅ Recreational & Technical Sidemount Courses
✅ Personalized setup and in-water tuning
✅ Progression into decompression and overhead environments

Sidemount isn’t just moving your tanks — it’s refining control, awareness, and efficiency in the water.

If you’re in Guam and curious about making the switch, send me a message. Let’s build a system that fits you and a skillset that elevates your diving.

With the incredible photos and videos today’s phones are making, this is a great option. Good down to 196 feet.

Look what just arrived at MDA, the Oceanic Dive Housing!
Turn your iPhone into an underwater camera and dive computer. Now compatible with iPhone 16 Pro Max (shipping with Retrofit Kit). The patent-pending Oceanic+ Dive Housing lets you capture stunning, color-corrected photos underwater—while using your iPhone as a fully-functional dive computer with the Oceanic+ app.

Ready to Change the Way You Dive?

Rebreather diving isn’t just another certification — it’s a completely different experience underwater.

Longer bottom times.
Minimal bubbles.
Closer marine life encounters.
Precision control of your breathing gas.

Whether your goal is extended range, serious decompression diving, or simply experiencing the ocean in near silence, a rebreather opens doors that open circuit just can’t.

I’m now scheduling upcoming rebreather courses, from entry-level recreational CCR through advanced and decompression pathways. Training is small-group, detail-focused, and built around solid fundamentals — because this is equipment that rewards discipline and skill.

If you’ve been thinking about making the jump, this is your sign.

Message me directly for course dates, prerequisites, and what to expect.

Casey’s Hollis Prism2 course just kicked off last week!

Congratulations to Casey and Elliot for completing their Advanced Wreck Diver and Diver Propulsion Vehicle (DPV) Diver courses!

Over these dives they sharpened their reel work, tightened up buoyancy and trim, and demonstrated strong awareness in true overhead environments—then added smooth, controlled DPV operation to extend both efficiency and range. Solid performance across the board. Both courses demand focus and discipline, and they met the challenge!

And they’re not slowing down—Casey is stepping into the world of CCR diving using the Hollis Prism 2 rebreather, and Elliot has begun his Normoxic Trimix course on his Liberty Sidemount CCR, pushing toward safe operations down to 200 feet.

Good work. Let’s keep building
