Why I became a Technical Diver…



In his debut blog for Scubaverse, Commercial and Technical Diver John Wheeler explains why, for him, recreational diving was never going to be enough…

From age 12 to around 18 I followed the same path as most, from PADI Open Water through to Rescue Diver. But with a child-like sense of adventure, always wanting to see what’s around the next corner, over the next hill or what lies in deeper waters, there was only one direction for me. The last 3+ years of my diving have been a journey, picking up the next stage and diving deeper and longer.

I first came across Technical Diving when in Dahab on holiday. Dive sites like the Canyon and Blue Hole felt like a tease: being able to see the sites below me but being unable to explore with a single cylinder and an all to rapidly approaching no decompression limit. Chatting to instructors and guides out there and hearing about helium and twinsets stuck in my 16 year old mind, and once back in the UK, with Google and YouTube at my finger tips, I began researching what would become an obsession.

One of the biggest questions I get now, from non-divers and new divers alike is “how deep do you go?”. I try my best to avoid the question as its pure ego fuel. I see no point in bounce diving deep just to say you have. Diving for me needs a purpose and having spent the last 4 years living in Plymouth, wreck diving has been my focus.

So how did Technical Diving improve the explorer in me? Technical Diving covers two aspects in my eyes: to dive for longer safely and to dive deeper safely. The first step for me was to add more gas to my shallower dives. More gas = more time and a greater safety margin, starting initially by moving to a twinset and then, in simple terms, adding more stages and different gas from there.

Technical diver training is far more intensive than recreational training; it has to be. With greater associated risk comes greater theory and skills to minimise those risks. But these skills not only benefit your deeper diving, they benefit ALL diving. Greater buoyancy control enables you to take better photos, move without disturbing wildlife and be more comfortable in the water, all making your diving more enjoyable.

The journey into Technical Diving is an ongoing one, the next step for me is jumping onto a rebreather… more on that soon!

John cut his teeth diving out of Plymouth whilst studying for a degree in Marine Biology and Oceanography. Whilst at university he undertook a professional diving course which set him up for his career in diving. Having thoroughly explored the easily accessible wrecks around the south coast there was only one way forward. Jon is now a technical diver ever looking to forward his skills to explore deeper and longer.

Peli proud to support COVID-19 vaccine distribution



We know Peli from its popular camera cases, but from discovery to distribution, Peli’s temperature-controlled packaging is now delivering COVID-19 vaccines all over Europe and the Middle East

With the pandemic recovery just underway, COVID-19 vaccines and therapies are rapidly becoming available for use and they must be safely distributed worldwide, within their required temperature range. Peli’s BioThermal™ division is providing temperature-controlled packaging to meet this critical moment, protecting these crucial payloads.

Peli’s innovative cold chain packaging has been trusted for nearly 20 years by pharmaceutical manufacturers to safely ship their life-saving products around the world. To meet the current challenge, they have adapted their existing products to provide deep frozen temperatures when required for the newly developed life sciences materials. Current and new offerings will ensure the cold chain is maintained throughout the vaccine or therapy’s journey, maximising efficacy and patient health.

“We know that pharmaceutical companies are in all phases of the development process for vaccines and therapeutics and working tirelessly to bring safe and effective drug products to market quickly,” said Greg Wheatley, Vice President of Worldwide New Product Development and Engineering at Peli BioThermal. “Our engineering team matched this urgency to ensure they have the correct temperature-controlled packaging to meet them where they’re at in drug development for the pandemic recovery, from discovery to distribution.”

Peli BioThermal’s deep frozen products use phase change material (PCM) and dry ice systems to provide frozen payload protection with durations from 72 hours to 144+ hours. Payload capacities range from 1 to 96 litres for parcel shippers and 140 to 1,686 litres for pallet shippers.

New deep-frozen solutions are ideal for short-term vaccine storage, redirect courier transport of vaccines from freezer farm hubs to immunisation locations and daily vaccine replenishment to remote and rural areas.

Peli BioThermal temperature-controlled packaging is currently being used to distribute COVID-19 vaccines and therapeutics, either directly or through global transportation providers, in Denmark, France, Italy, Germany, Spain, Sweden, and the UK as well as in Kuwait and Saudi Arabia in the Middle East, with more countries set to join the list as the pandemic recovery process rolls out.
