Innerspace Explorers skills

Innerspace Explorers (ISE) was founded by Achim Schlöffel in 2008. Previously a GUE instructor, Schlöffel began ISE to share technical diving content via YouTube. Over time, his channel grew and became a valuable resource. In these videos, skills demonstrations, tutorials, and technical diving topics are regularly posted.

The skill videos are filmed in warm water with excellent visibility and slow pacing. This clarity makes them easier to follow than many other demos.

Style, Opinion & Value

Achim presents tutorials with strong opinions. You may not always agree with him, but his content often sparks useful debate among instructors. Some dive agencies might benefit by observing how much content ISE publishes and how it engages divers.

Skills like gas switching and “cleanup” are beneficial for students training in decompression procedures. These demos show what lies ahead when advancing to trimix diving.

Skill Demonstrations & Tutorials

Below is a handpicked list of ISE skill demos and tutorials from YouTube. These videos showcase techniques, reasoning, and workflows that complement your technical diving education.
