About This Podcast
The Scuba Gear Lab applies Consumer Reports-style testing to life-support dive equipment, publishing spec-driven comparisons that prioritize safety and performance over marketing claims. Our mission is to give divers the technical data and failure analysis they need to make confident, high-stakes purchasing decisions, as well as educate every diver -- from students to professionals -- about the gear their life depends on.
