Guest Speakers at The Great Northern Dive Show 2018

The Great Northern Dive Show 2018 will feature a wide variety of guest speakers from all areas of scuba diving.

Paul Duxfield

Duxy has been a regular figure on the dive industry scene for the last 15yrs.
Upon returning from Egypt in the early noughties where he worked as a guide, he quickly established himself as the ‘go-to guy” for newbies to give the best advice upon starting out in underwater photography. Being sales manager at the two biggest UW photo retailers in the UK, he also found time to write for the popular diving press and has conducted over 50 underwater photo workshops here and around the world. Alongside his regular club and dive show appearances.

Endlessly patient and full of infectious enthusiasm he likes nothing more than helping people with their questions about underwater photography from what camera to buy, and then on how to use it and the necessary accessories to go with it.

His mantra has alway been ‘Best Advice’ even if that meant losing a sale occasionally, building up trust amongst the people he dealt with.

This year on the prompting of a couple of his trip regulars and stalwarts of the club and competition scene Phil and Anne Medcalf he joined with them to start up Blue Duck Photography drawing on all their skills so they could join forces and deliver the very best in sales and photo training.

They’ve already had a very fast start and been delivering photo and digital editing advice to dive clubs around the country in a very short time.

Garry Dallas

Garry, known to many as ‘Sidemount Bob’ or ‘Chewie’, is truly fascinated by the underwater world, equally as happy being mesmerized by the gracefulness and beauty of marine life, as he is with the eerie silence of deep wrecks soaked in history, not to mention the remote, stunning speleology decorating the caves around the world, photographing those special moments along the way.

For nearly 20 years, spending most of his time underwater, he figured that becoming an instructor and passing on his knowledge would be time well spent, and so he did just that, improving divers abilities wherever he goes. Having qualifications in all the major training agencies in OC, SCR and CCR, his intrigue into various kit and configurations led him to research the theory, understanding and practicalities into Sidemount diving and its application for all disciplines including rebreathers, for which he is globally reputed.

He finds it in his nature to seek adventure and push himself, clearly evident in his cave diving explorations and ventures; Presenting/speaking at primary and secondary schools, dive centres and national/international dive shows.

He’s a Recreational, Technical and Cave Instructor Trainer, co-owner and director of training for RAID UK & Malta training agency, a key member of the “Apeks Cave Exploration” and “Apeks Tek Testing” teams, exploring newly discovered cenotes in the Yucatan district, Mexico as well as mines and caves in UK and Spain.

He says ” Teaching and diving around the world, I feel privileged to be able to call this surreal, enticing and inspiring underwater realm my office, humbled every time I’m in it… that’s why I enjoy my ‘job’ and would love others to have that same experience. ”

John Kendall

John Kendall is a GUE technical, cave and CCR instructor. Since he was a small child, John has been fascinated by the underwater environment and the possibilities of adventure, and he is grateful to GUE for helping him to turn those childhood dreams into reality.

As an instructor, John regularly travels around the world teaching GUE classes and helping to build local GUE communities. He is also the project manager for Project Baseline Malta. For the last 4 years, John has been working with underwater 3D Photogrammetry as a technique for nautical archaeology. This cutting edge technique allows for digital 3D models to be created of shipwrecks, and allow researchers and scientists unparalleled abilities to manipulate and navigate the sites from the comfort of their own computers.

From the frigid waters of the Baltic to the toasty Mediterranean sea, John and GUE have been accumulating data and generating some cool looking imagery of deep water wrecks, and John is going to share some of it with us.  When not diving (which is rare), John is also a commercially qualified UAV pilot.

Donovan Lewis: Blue Planet Aquarium

My entire life I’ve been obsessed with Sharks, their mystery, perfection and resilience to natures hardships make them one of the most incredible and talked about animals of today.

This year I was given a fantastic opportunity to work alongside the White Shark Diving Company in Gansbaai, South Africa throughout May and June. I was sent out by the Blue Planet Aquarium, based in Ellesmere Port, to go and gain experience and insight into shark conservation and research, and to learn what it takes to work alongside the worlds most recognisable shark species, the Great White.

The South African White Shark population was studied greatly throughout the 1990’s and was the subject of many documentaries. However this population of White Sharks, and the incredibly dynamic ecosystem that they call home, is now under threat from a range of things such as overfishing and competition. My talk will focus on these issues and reveal a South African scientific first, which also resulted in my participation in a White Shark dissection.

Dave Thompson

Scuba diving is a sport that can be enjoyed by people of all ages and abilities. Through his presentation titled “Able2 – Dive”, Dave Thompson MBE DL will share his passion for diving which he describes as ‘depth therapy’.

All divers appreciate the need for good buoyancy, as it results in a feeling of weightlessness. For many disabled divers it can support manoeuvrability that is impossible to achieve on dry land.

In 1989, Dave sustained a spinal cord injury while playing American Football and is now a full-time wheelchair user with limited use in his left arm and none in his right arm or legs. Despite this, he has completed his PADI Open Water and Advanced Open Water qualifications, plus several specialities and, in the past eight years, he has recorded over 180 dives in the UK and abroad.

Dave and his colleagues from Warrington Disability Partnership will be staffing an exhibition stand promoting their annual ‘Going the Extra Mile Scuba Challenge’ which has raised over £25,000 towards their annual Disability Awareness Day.

Since its launch in 2011 Dave has set several personal bests including completing the mile in a gruelling one hour and 49 minutes. In 2013 Dave completed the mile using a Poseidon Rebreather, the event was featured on ITV Granada Reports.

Dave’s philosophy of life is: ‘it’s about what we can do that’s important, not what we can’t do’.
