ECHO is a gas analyzer built for technical divers who take their breathing gas seriously. Whether you're blending nitrox for a deep reef dive or mixing trimix for something more ambitious, ECHO tells you exactly what's in your cylinder, so you can focus on the dive, not the doubt. Connect it to the Divesoft App via Bluetooth and your whole blending workflow just clicks into place, from analysis to labeled cylinder in minutes. ECHO also checks for carbon monoxide in your breathing gas - the kind of contamination you can't see, smell, or taste, but absolutely need to know about before you descend. It's the safety check that's easy to skip and impossible to regret doing. The helium measurement is handled by a clever acoustic sensor that never needs replacing. Less maintenance, one less thing to worry about between trips. Light enough to toss in your dive bag without a second thought, and tough enough to survive the journey - ECHO is the kind of gear that quietly earns its place on every packing list.
