Innerspace Explorers

Who are we?

ISE stands for Inner Space Explorers. It is an organization with the intent to promote underwater explorations in all its fascinating aspects. As it was founded in 2008 by internationally renown instructor and explorer Achim R. Schlöffel, the name of the company was chosen with care and purpose.

Let us explain...

What ISE and foremost underwater explorations mean to us, is best shown by the life story of our founder:
Achim started diving in 1980. At the age of 18, he went to Florida where he worked as a diving instructor and started his commercial diving career. Prior to starting his own company ‘Classic-Dive’ in 1996, Achim worked as a diving instructor out of Munich, Germany.
In 2002 Achim founded THE-INNER-SPACE.COM. A company dedicated to the highest quality dive training and exploration around the world. THE-INNER-SPACE.COM still serves as a resource center for the diving community all over the world. From 1999 until 2008 Achim has taught various courses and levels in technical diving for GUE where he was the only German speaking Tech 2 instructor worldwide.

Achim´s greatest passion for diving was, and is to this date the exploration of the underwater world. Be it an unexplored wreck, or an uncharted cave. In his pursuits throughout the years, he took part in various professional diving expeditions all over the world.
Knowing that many divers share his interest in exploration, but most lack the skills and knowledge to perform true exploration in difficult environments in a safe way, Achim decided that it was time for him to move forward and remedy this situation. He formed ISE - Inner Space Explorers.

" customers always asked for the most rigorous and demanding training. They want to get the real experience, feel the real limit, and in the end know that they had to give everything. When I realized that I could not offer that anymore I knew it was time to move on..."

For that reason, ISE was founded by an active explorer and builds its core of technical instructors exclusively from people that have a similar history and are active in what they teach.
