Halcyon pressure gauges are as reliable as they are accurate. We start with an industrial-strength spring designed for pressures beyond 5,000psi (400bar), high-quality materials, and a highly visible, luminescent face which. makes this a common favorite among divers in all environments.

Halcyon Manufacturing was formed to support the needs of demanding divers. Many of these divers are actively exploring far-reaching recesses of the underwater world. During these international travels, divers often use or dive with people in both metric and imperial systems of measure. Halcyon is pleased to support our global community with a dual, metric/imperial gauge, allowing easy integration between teams and as an easy reference for individuals in both measurement systems.

• Dual-unit pressure gauge (bar and psi)
• Nickel-plated brass with mineral glass lens
• The weight and size of our Master SPG gauge make it well suited as a primary SPG.
• The large, clear display is easy to read in all diving conditions.
