Aron started diving in 2005 in an attempt to break away from the rat race. Since then, his passion for technical diving has led him to some of the best diving locations in the world.

Aron has written for dive publications and training organizations, developed products with Fourth Element, Hollis, and Ocean Reef, and has regularly helped organizations develop training outlines. Aron has filmed documentaries and commercials along with hosting numerous TV and film productions including National Geographic’s One Strange Rock, Dive Odyssey, and worked with Monty Halls on Channel 5.

One of Aron’s personal highlights was a four-year project that started in 2011 and culminated with Team Blue Immersion discovering the wreck of the USCGC Alexander Hamilton at 95m/311ft, 20 miles off the coast of Reykjavik. The team conducted a deep exploration dive and then, after communicating with the US Coast Guard and the families of the fallen men, attached a memorial plaque on the ship. Aron is a active member of The Explorers Club.


Martin Cridge - Captain

Without Martin The Dirty Dozen Expeditions wouldn't exist. A few years back, Aron and Martin spent a full year diving together in Truk Lagoon. One evening, after a day of demanding dives, they sat, had a beer, and came up with their ideal CCR wreck dive itiniary.

The first ever Dirty Dozen trip was the result of that beer and the rest is history. Martin has lived in Truk Lagoon for six years and alongside Aron, is on board all of the Dirty Dozen's trips in Truk. Before working on the boat Martin was a chamber operator at the DDRC in the UK.


Richard Lundgren - Special Guest

Richard Lundgren has worked around the world as a professional diver for more than 20 years. He has been fortunate to participate in many sensational exploration projects including the HMHS Britannic (sister ship of the RMS Titanic) and the discovery of the mighty admiralship Mars the Magnificent, sunk during the Nordic seven-year war in 1564.

Lundgren is a founding member of the exploration organization GUE, Global Underwater Explorers, and serves on the board of directors.

Mark Powell - Special Guest

Mark had his first diving experience at the age of 10, when he did a try-dive in a local pool. He was hooked from that point onwards. He learnt to dive in 1987 and has been diving ever since. Mark is a TDI Instructor Trainer and a member of TDI’s Global Training Advisor Panel. He is a regular contributor to a number of diving magazines and a regular speaker at diving conferences around the world.

Richie Kohler - Special Guest

Richie Kohler’s passion for technical scuba diving and maritime history means he has explored some of the most challenging shipwrecks in the world, including the Andrea Doria and HMHS Britannic.

Searching for lost ships has led him to locate and help identify numerous lost vessels, including the U-215, a German mine laying submarine on the Georges Banks off Nova Scotia, USS Murphy, a WWII destroyer that was crushed and forgotten in the New York approaches, and many others. But it would be the identification of a German U-Boat, the U-869, that would catapult his diving career into the world of television and documentary filmmaking.


Jill Heinerth - Special Guest

A pioneering underwater explorer and film maker, Jill Heinerth has dived deeper into caves than any woman in history. With a collection of magnificent images, from inside Antarctic icebergs to crystal underwater cathedrals, Jill shares a glimpse of a breathtaking world few will experience in person.

Jill’s photography and writing have been featured in prominent publications and major media outlets around the world.

Nataliia Zharkova - Special Guest

After a ten-year career in competitive swimming that began at the tender age of seven, it’s no surprise that Ukrainian freediver Nataliia Zharkova is a specialist in the Constant Weight No Fins (CNF)category.

But after breaking four CMAS world depth records, being the third deepest female in Free Immersion (FIM), and the sixth deepest in Constant Weight (CWT) in AIDA's 2018 rankings, it’s fair to describe Zharkova as a very strong all-round athlete. In a period where the level of competition amongst world-class female freedivers is at its peak, this is no small achievement.


Nick Hollis - Special Guest

The driving force behind the Hollis brand since its launch in 2007, Nick’s passion for scuba diving began earlier than most: as an 8-year-old diving with his father, Bob Hollis.

Today, Nick leads the design of gear for both the recreational and technical markets, focuses on the customer experience, and works to continuously expand the rebreather community.


John Kendall - Special Guest

Since first learning to dive in 1993, John has traveled around the world diving and teaching.

John is a GUE Instructor Trainer and a Fellow of The Explorers Club. As a member of The Dirty Dozen, John specializes in showing our clients photogrammetry in Truk Lagoon and Bikini Atoll.


James Draker - Special Guest

James started diving at an extremely early age and has kept it up ever since. Through years of diving James has worked his way up to an Instructor Trainer for TDI and IANTD.

James is probably most well-known for his cave exploration, taking his SF2 Rebreather on extremely long dives in deep caves such as Eagles Nest and Diepolder 2 and 3 in Cave Country, Florida, where he and Marissa Eckert reside.


Marissa Eckert

Marissa steadily worked her way up to becoming a Cave and Rebreather Instructor. She enjoys doing deep, long dives on her SF2, hiking through the jungles of Mexico to find awesome new cenotes to dive, and photographing their adventures along the way! Marissa and James are together in Truk Lagoon doing a special charter.

Will Goodman - Special Guest

Following a year’s training and preparation, Will Goodman, a technical diving Instructor Trainer, and Guinness World Record holder for the longest scuba dive, descended to a recorded depth of 290m using an unmodified, JJ-CCR (closed-circuit rebreather).

At this depth, all his computers stopped registering further but it is estimated that the actual depth exceeded 300m.



James Evans - Sales Manager

Leaving city life behind him, James started working with Blue O Two in 2013 knowing that his work could take him around the world. Starting as a dive travel consultant, he is now one of the senior sales managers and has oversight of all the trips in The Dirty Dozen's calendar.

He is probably the person you will meet at the Blue O Two stand at dive shows.
