SEASON 2 EPISODE 5

In episode 5, Maxwel recounts the entirety of the Prism 2 certification process. He identifies challenges he overcame, things he didn’t expect, the highs and lows and how the course will continue to enhance his diving. He also explains how the use of the P2 has influenced his photography and what’s next in his rebreather journey.

FROM THE INSIDE OUT, SEASON 2 is a 5-part web series that documents what it takes to get trained up on Hollis Rebreathers' flagship Prism 2. Commonly used in the fields of scientific research and media/content creation, the Prism 2 is the standard by which all rebreather technology is held in the diving world.

Join us over the next eight weeks as we take you behind-the-scenes in the classroom and out in the field as we follow master lensman diver Maxwel Hohn as he undertakes the process of becoming proficient in the use of the Hollis Rebreather Prism 2. We'll watch Maxwel’s first steps and early emotions and take you all the way to graduation day as he dons the P2 on his first rebreather dives. Enjoy this story of the Prism 2 Rebreather, from the Inside Out.

EPISODE 1
Getting Ready

SEASON 2 EPISODE 1

We begin our journey by getting to know Maxwel Hohn and diving deeper into his motivations for becoming rebreather certified and what he hopes to achieve with his new skillset. Along the way, we candidly address the emotional and physhological hurdles that must be overcome when undertaking a fresh, unknown challenge.

Rebreather Setup

SEASON 2 EPISODE 2

In Episode 2, we familiarize ourselves with Maxwel’s new instructor and classroom as he attends his first day of training. He learns to set up his Prism 2, then—under the watchful eye of his instructor—gets into the training pool and gets his first practice session in with the P2.

EPISODE 3
Getting Into the Pool

SEASON 2 EPISODE 3

Now that Maxwel has learned the ins and outs of a rebreather, it’s time to test his skills in the water. He quickly learns that there are a few key differences between open and closed circuit diving, including managing buoyancy. After a day of diving, Maxwel starts to find his bearings in the relative safety of a practice pool, and is ready to head out to the ocean to tackle his first open water dive.

EPISODE 4
Open Water Diving

SEASON 2 EPISODE 4

After getting his bearings in the relative safety of a practice pool, Maxwel heads out to the ocean for his first open water rebreather dive. He’s nervous about his buoyancy control, but excited to experience the silence of a rebreather and be able to get closer to marine life. Maxwel and his instructor enjoy their first dive by testing a few more skills, swimming with a school of rockfish, and sharing a few fist bumps along the way.

The team

Maxwel Hohn

Maxwel Hohn Photographer, Videographer and Prism 2 Ambassador

An adventurer, photographer and filmmaker, Maxwel Hohn has a passion for documenting and exploring the underwater world. He is a recreational, technical and commercial diving instructor with over 4000 dives. One week he could be squeezing into a river canyon filming salmon for a documentary, and the next week he could be traveling the coast of British Columbia collecting data for Fisheries and Oceans Canada. Maxwel's goal is to utilize the Prism 2 Rebreather for underwater videography. With extended bottom time and a closed-circuit breathing loop (no bubbles), it is the ultimate tool to explore, and document the underwater world in more unique ways.

Nick Hollis

a history of Hollis rebreathers

Our rebreather history runs deep with stories from Hollis founder and renowned industry pioneer Bob Hollis. In the mid-1960s, Bob had his first rebreather experience; he used Draeger units to get close to Sea Otters and other marine life in Monterey Bay. By 1970, Bob made some of the first dives on the Electrolung rebreather, using Heliox down to 300 feet in Honduras and Bonaire and filming ship wrecks and deep reefs. In 1990, Bob & Oceanic developed the “Phibian” rebreather, which at the time was the only commercially available unit. And in 2000, under two separate contracts with the United States Naval Surface Warfare Command, Hollis developed and delivered a unit called the “ATUBA” (Advanced Tactical Underwater Breathing Apparatus). This solid back-ground of rebreather technology directly led to the development of the our flagship Prism 2 rebreather.

Most Exciting Thing About the Prism 2

prism 2

The Prism 2 is a fully closed-circuit rebreather, ideal for exploring open ocean, cave, or wrecks. It can be either electronically or manually controlled, and its simple design benefits photographers, underwater researchers, and technical divers. It's been tested to have one of the lowest WOB of any mixed gas CCR on the market, making it extremely comfortable to dive.

Prism 2 includes shoulder mounted counter lungs and a rear mounted radial scrubber for easy breathing with low resistive effort and low hydrostatic loading.
