ECHO Solid State is a gas analyzer designed for technical divers who take the quality of their breathing gas seriously. Whether you're blending nitrox for a deep reef dive or trimix for a more ambitious undertaking, ECHO tells you exactly what's in your tank, so you can focus on the dive, not the doubts.
Connecting it to the Divesoft.App via Bluetooth makes the entire blending workflow automatic, from analysis to tank labeling in minutes.
ECHO also checks for carbon monoxide in your breathing gas – a type of contamination that is invisible, odorless, and tasteless, but absolutely necessary to detect before diving. It's the safety check that's easy to overlook, but impossible to regret.
Helium measurement is handled by an ingenious acoustic sensor that never needs to be replaced. Less maintenance, one less thing to worry about between dives.
Light enough to pack in 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 gear list.
