“Depending on location, everyone’s a little bit different about how they like to set their harness up. But at the end of the day, the coolest thing about the Katana 2 is that you can run it however you want. Technical divers love to modify and tweak … depending how they’ve been diving in the past, or how they were taught or how they teach their students … The key benefit of the Katana 2 is that those people can make all of the adjustments and decisions for themselves.”
— Nick Hollis, Brand Manager
