Hi and welcome! My name is Leo Karlsson, and I have a deep passion for technology, underwater exploration, and the mysteries hidden beneath the ocean's surface.

On this channel, you’ll join me on real-life expeditions where I scan the depths of lakes and seas using side-scan sonar, AUVs, underwater robots, and other advanced tools. This isn’t a typical tutorial channel – instead, you’ll experience raw adventures, discoveries, and unexpected underwater findings.

New LIVE videos are posted regularly – so don’t forget to hit subscribe and ring the bell to join the next underwater adventure!
