ECHO is a gas analyzer designed for technical divers who are serious about managing their breathing gas. Whether you're blending nitrox for a deep reef dive or trimix for a more ambitious endeavor, ECHO tells you exactly what's in your tank, so you can focus on the dive, not the doubts.
By connecting it to the Divesoft app via Bluetooth, the entire blending workflow becomes automatic, from analysis to tank labeling in minutes.
ECHO also checks your breathing gas for carbon monoxide – a type of contamination that is invisible, odorless, and tasteless, but absolutely necessary to detect before diving. It's the safety check you tend to overlook but can't regret.
Helium measurement is handled by an ingenious acoustic sensor that doesn't need to be replaced. Less maintenance, one less thing to worry about between dives.
Light enough to toss into your dive bag without a second thought and rugged enough to withstand the journey, ECHO is the kind of gear that quietly earns a spot on every kit list.
