Andy Connor is a mechanical engineer by training and has a PhD in mechatronics. Currently he is a senior lecturer at Auckland University of Technology. He is also a technical diving instructor, explorer and writer. Dr. Connor is a typical lecturer; always seeking perfection. That's why he is one of those instructors who enjoy filling gaps through presenting distinctive specialties.
Andy's diving interests mostly relate to technical wreck penetration beyond the daylight zone. However, his big project at the moment is surveying old gold mines. He and his fellow divers have started indexing known locations against historical references, plus searching for other sites. They have got around 120 individual mine shafts at present - one is definitely flooded and would make for a very exciting dive. Of the 120 mines they know about, Andy thinks about 20 of them will be flooded and accessible - and essentially untouched since they closed. The mines all date from the early 1900s, and the last of them closed around 1949.

It didn't take long for Ag to become hooked on blowing bubbles - after her first underwater breath she thought "this is what I want to do with my life!!" Indeed since then diving has been at the very center of her existence. Initially fascinated with reefs and fish, it wasn't long until the focus shifted to wrecks.
Captivated not just by their sheer beauty but also by their stories and history, she went from being a keen and avid wreck diver to a wannabe maritime archaeologist and did a Graduate Diploma in Maritime Archaeology at Flinders University. Her desire to pursue untouched and pristine wrecks meant going ever deeper and having to play with more gear and gases to do so.
Afterwards it is the caves, both wet and dry, that have her enthralled and she is most passionate about the exploration of never before seen passage. Ag spent a year living and diving in Florida's cave country, where she got her first taste of laying line. It is a phenomenal feeling to reach a place that no other human has ever seen before and she was hooked. She feels privileged to have seen the far reaches of some of the most beautiful caves in the world in Australia, the US and the Bahamas.
Agnes died in Tank cave in Australia on February 27th, 2011.

Don has been involved in diving since 1974, conducting recreational and technical training. He is an Instructor Trainer Trainer for IANTD and DAN. He was an electronics engineer in the British Army for 22 years. The main reason he enlisted was because they offered adventure sports. Don began diving on "day one" and organised and led expeditions for the soldiers to many destinations around the world.
He was a member of the first Army sanctioned sport Trimix expedition in '96 and one of the first divers to see the sunken HMS Pheasant. His swan song expedition in the military was a 2 month diving exploration in the Falkland Island, diving totally remote sites on the furthest of the islands.
For the last 17 years technical diver training has been his full time occupation, he's been permanently located in South Africa, most of the training is done there, with some expeditions to more remote locations which you can only reach by 4 x 4 vehicles, and where you need to take everything, including gas, compressors, camping gear, food and more.
Some of his favourite sites are Boesmansgat Cave; a great back to earth experience in every sense of the word. Zimbabwe's Chinoya Caves, Namibia's Lake Otjikoto, Lake Guinas, Harasieb, Gamgarab, Dragon's Breath; and many more to explore, Antarctica's diving next to icebergs and the Mexican caves – where his wife André had to drag him back home. Then there are also the more familiar trips along the South African coastlines, Red Sea, Mauritius, Florida, etc...
Don's main diving passion is Closed Circuit Rebreathers and cave diving. His area of expertise is training all forms of technical diving. He currently resides at Komati Springs dive site next to a 186m cave system in a Big 5 Game Reserve in South Africa with André.

T. Timothy Smith
T. Timothy Smith earned his PhD in Biomedical Sciences from the University of Hawai'i in 1990 where his love affair with diving began. Eager to document the abundant marine life available in Hawai'i he purchased a small underwater camera that took 110 format film. Yes, that was a long time ago. After many incarnations of underwater photographic systems, he now shoots with a professional level Nikon digital system. Underwater photography is a very expensive mistress. So, between exotic diving locations and the latest camera gear, Tim is usually broke. Tim has dove extensively in the warmer waters of the world and has no interest in donning a dry suit or going to Antarctica. However, he will put on a 3 mil for cave diving, if the occasion arises. Tim is an active member to the Underwater Photographic Society of New York and lives in the New York City metro area. Tim has contributed several of his underwater images to the magazine and will continue to share and document the joy of diving. Let's make bubbles together!
Born in 1957, Flavio Fanelli has a degree in mechanical engineering and an MBA. He also has some background in the army from his twenties. Flavio started diving in 1974, mainly because of the TV show Sea Hunt. He loved the character Mike Nelson (Lloyd Bridges).
Different jobs meant different countries, so Flavio moved between South America, North America and Europe. That gave him the opportunity to dive in so many different places. He went all the way from spearfishing to OC technical diving. eCCR is his last acquisition; still in the learning curve since late 2014. Now he's back in Italy since 2010. Perhaps his last stop, who knows?
Flavio really likes to dive on wrecks, and he has been lucky enough to dive many. 2017 was a very special year for him, as he finally managed to dive the HMHS Britannic... one of his old dreams has just come true.

He first got certified in 2005 and has so far progressed to TDI Advanced Nitrox and Deco Procedures diver.
Warren's eventual goal is not just Trimix certification, but also to be able to safetly dive on the Andrea Doria and the U-869, two of the most demanding wreck dives in the world.
Warren enjoys both the challenge of planning and executing a difficult dive but also enjoys a relaxing dive over a colorful reef. His hope is to continue to contribute articles from the new tec diver's perspective and to encourage more people to learn to dive.
Born in 1968, Ayman is a psychiatrist from Amman, Jordan. He learnt to dive in 1995 in Hurghada, Egypt. Eight years later with more than 500 dives under his belt, he decided to go technical. He went with TDI to become an Extended Range Diver. Mixed gas is yet to come, specially that rebreathers are taking off, so Ayman is considering going silent as well. Two things are out of question: going pro and undertaking underwater photography.
Ayman is a vacation diver who enjoys both the challenging and the relaxing dives.
Reef dives from the shore at Aqaba, Jordan or Nuweiba, Egypt are two of his all time favorite choices. Wreck and cavern dives come second. A week-long liveaboard in the Maldives is what he's always looking for. Unfortunately that doesn't come except once every couple of years.
Andy had his first taste of diving aged just 16 in 1972 having been inspired by the James Bond film Thunderball a few years earlier. Regrettably like most teenagers he was distracted by heavy metal and other participant activities. In 1973 he joined the police becoming a specialist firearms officer and later a firearms instructor. Although partaking in try dives at every opportunity, he didn't formally qualify as a diver until 2003. Retiring from the Police in 2005 aged just 49 he used all his free time to both dive and further develop his skills first as an open circuit technical diver then crossing over to the "Dark Side" on closed circuit rebreather.
Some of Andy's most memorable dives involve the numerous wrecks around the UK especially the those around the Orkney's and Scapa Flow, numerous shark encounters around the world, and more recently exploring the Cenotes of Mexico, the interconnected shafts, passages and levels at Komati Springs in South Africa and Dragon's Breath Cave in Namibia. Now an advanced mixed gas CCR and full cave diver, he continues to seek out new and more challenging diving constantly striving to develop his knowledge and understanding of decompression theory and diving physiology. He will shortly be travelling back to Namibia to continue the exploration of Harasib Cave only 2.5 km from Dragon's Breath.
Julien is 35 years old (2016), born in France, though he has been living everywhere but in France for the past 16 years - and India is the place he calls home. He has a background in engineering, but after having worked in the automotive industry, in IT, in web design, in sustainable development, and doing the odd jobs as driver, kindergarden manager, writer or climbing teacher, he became a diving instructor.
He's been diving for close to 12 years, and since he enjoys traveling, has been exploring the underwater world in California, Cambodia, Cuba, France, India, Malaysia, Mexico, Philippines, Senegal, Sri Lanka, Switzerland, Thailand... And taught hundreds of courses in the process. Technical diving has proven to be the best way to connect his love of the outdoors, his passion for diving and his thirst for physical challenges and new theoretical knowledge.
Apart from currently being in charge of Technical Diving courses at Dive-Careers for Buddha View, Thailand, as well as the other Dive-Careers locations, Julien is also the head of Technical and Professional training at Temple Adventures, Pondicherry, India, and the founder of TechnicalDivingIndia.com, a teaching agency actively promoting and teaching Technical Diving in India and abroad. He's also collaborating with Planet Scuba Mexico, Puerto Aventuras on Cave and Tec diving projects.
Fabio has been diving for more than 35 years and he started diving when he was 14 to follow his father's step and act as his support diver. He has been diving exclusively air for 30 years, including tech deep air and air deco procedures. Then he moved quickly to advanced Nitrox and Accelerated Deco procedures and finally to OC Trimix in 2013. In 2014 did intro to caves. From that point he did like the technical diving mindset which matched the one of a pilot and he was most at ease with procedure, planning and decompression. He then moved to CCR in 2015 and he has gained experience in Air Dil, Air Dil Deco and Normoxic Trimix Diluent on APD Vision.
In his real life Fabio is an Air Force Officer who did (and when desk duties allow still does) fly high performance jets as Weapons and System Officer. He is also a FAA licensed Commercial Pilot Aircrafts Single Engine Land and Advanced Ground Instructor. He gained his private pilot license before he could legally drive a car and he has been flying since. He believes that the structured mindset that is associated with flying could be beneficial to diving.
Fabio is Italian and, beside Italy, he has been living in USA (Texas, Virginia and California), UK (Leicestershire and Buckinghamshire) and about to move to London and he hope to gain additional diving experience in UK.
