Ask a diver if they need to analyse their gas every time, and the reply is almost always, “Yes — every single time.” This exchange isn’t about doubt or mistrust; it’s about certainty.
Gas cylinders are filled daily, often with different mixes — sometimes Nitrox, sometimes Trimix. Fill stations might do it for you, or you might mix your own gases. Regardless of the process, verifying the gas composition is the final, critical step that each diver personally takes. It only takes a few seconds, and this quick check guarantees you exactly what you’re breathing, providing peace of mind and safety. That’s why a gas analyser has become just as vital as your dive computer or your planning tools. It’s an essential piece of your safety gear, and the Divesoft ECHO feels like a genuine next-generation instrument.
What Are We Measuring?
Most divers focus on two main components: oxygen and helium.
For Nitrox dives, the oxygen percentage is key. It determines the maximum safe depth and influences your entire dive plan. When it comes to Trimix, helium enters the equation, affecting how the gas behaves during descent and ascent, and also setting safe limits.
However, there’s another important aspect that is often overlooked: gas quality. The Divesoft ECHO can detect contamination— carbon monoxide, a colourless, odourless gas that can be present in improperly mixed or stored gases. Since we can’t see or smell CO, checking for its presence is crucial for safety.
Simplifying Gas Checks with the ECHO
The strongest part of the ECHO is its intuitive design. The display is easy to read, the controls are logical, and the whole process feels clean and efficient. This matters because safety equipment only works when divers actually use it consistently. The ECHO makes gas analysis simple enough that there is no excuse to skip it.
In use, the results were excellent. Readings were clear, stable, and consistent, and the gas-checking process was quick and repeatable. The oxygen and helium analysis performed exactly as expected from a high-quality technical diving analyser. Hold the analyser to the valve, check the number, and label your cylinder. Simple, quick, and essential.
Goes One Step Further
As with most modern technology, this device features a dedicated app—only this one is truly worth your time. Just like the analyser itself, it’s designed to be simple and intuitive. With clear displays, real-time data, and convenient data storage, managing multiple cylinders, reviewing past analyses, and printing labels has never been easier. Label printing can be done seamlessly via Bluetooth directly from the app or through USB straight from the analyser. Marking your cylinders has never been more straightforward!
A New Sensor Technology for Longer Life
Most analysers rely on galvanic oxygen sensors, a technology divers are familiar with. But the ECHO can also be equipped with a cutting-edge solid-state oxygen sensor. This new sensor operates on a different principle, does not contain electrolyte, and offers significant advantages: longer lifespan and minimal maintenance.
The Verdict
The Divesoft ECHO is an excellent gas analyser and a strong step forward for modern diving safety. It is easy to use, intuitive, compact, and highly practical. Its integration of O₂, He, and CO analysis makes it a more complete tool for CCR divers, technical divers, trimix users, dive centres, and anyone who takes gas verification seriously. The addition of CO detection is the feature that really sets it apart. It feels relevant, necessary, and exactly where gas-analysis equipment should be heading.
At Dolphin Scuba, we’ve proudly adopted the Divesoft ECHO as our standard for gas analysis. Every cylinder we fill is tested with this next-generation equipment, guaranteeing accuracy, safety, and peace of mind for our customers. Experience the difference—visit us today and dive with confidence!
