Dan Macherel

JJ-CCR Level 1 Instructor

Dan Macherel developed a passion for Tec diving during the mid eighties when diving the deep lakes of Switzerland. Ever since, he travels the globe to places including French Polynesia's crystal blue waters to Florida cave country and from the wrecks in Chuuck Lagoon to the Red Sea.

With an offshore commercial diving background, he is also a decompression chamber operator and trained as dive medical technician. Working full time as a dive professional he splits his time between teaching Tec diving and actively Tec diving himself.

Dan offers CCR training for a variety of units including the JJ-CCR. Having started diving with a rebreather over a decade ago, he is experienced to dive with nine different units teaching six of them including some at IT level. No CCR on the market is perfect; each unit has its strong and weak points, which he discovers while training with world-renowned CCR instructors and as he gains experience using the units he owns.

With a selection of rebreathers available for rent, you have the opportunity to train and dive with several units, hence allowing you to make a more informed decision when it comes to buying your CCR unit of choice.

Dan relocated to Australia in the nineties, where he runs his own business on the Central Coast, in New South Wales about 70km North of Sydney. Dan's dive store caters exclusively for both open and closed circuit Tec divers. Besides dive equipment, spare parts and sofnolime 797, the store is equipped with a state of the art compressor using continuous flow and membrane, allowing storage of gases in 20 banks. The premixed gases are either ready to be boosted into your own cylinders or available to fill rental cylinders from 2 to 15 litres.

Courses taught in English or French.
