ISE stands for InnerSpace 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. InnerSpace Explorers was founded to support divers around the world, in their desire to receive the best training available. ISE offers the most demanding, challenging and intense training in the industry. Our training is free from all the marketing related advertising style contents, that you may find elsewhere. We are strictly focused on no nonsense education to enhance the thrill, safety and ultimately the fun of 'Your Passion'.
