X-RAY MAGAZINE FEATURE

Interview with Jakub Šimánek

Jakub Šimánek lives for diving and dives for a living. He inherited his passion for the underwater world from his father at a young age. Currently, a Factory Instructor Trainer for the Liberty closed circuit rebreather (CCR), Jakub has been a part of the development team at the dive equipment manufacturer Divesoft since 2012.

While his main focus is Liberty CCR and Liberty Sidemount training, he also works as a dive analyst, consultant, test diver and “crash test dummy.”

He has been diving with a Liberty since the very first prototype and has helped with many SW and HW innovations (CCR bailout mode included). Since 2017, he has been collecting and recording his experiences and methodics using bailout rebreathers. In addition to obtaining a master’s degree in education, Jakub has developed a rebreather training program and trains instructors, trainers and divers from all around the world, military included.

Clearing Mines in the Sava River of Bosnia

Landmines. They are some of the most insidious weapons mankind has ever created. Invisible, hard to destroy and waiting years for their opportunity to kill. Tens of millions are scattered around the world. In fact, Czech police divers and bomb disposal experts returned from another mission in Bosnia, where they were looking for war ammunition, especially landmines, in the rivers.

Tech and Training

Mine-explosion victim statistics are appalling. According to last year’s report by a coalition of organizations known as the International Campaign to Ban Landmines (ICBL), landmines have killed more than 2,000 people in 2016 alone, injuring or crippling another 6.5 thousand. That is the highest number in the last 20 years.
