Diving air-pressure gauge
STANDARD/STAGE SPG HALCYON

Halcyon pressure gauges are as reliable as they are accurate. We start with industrial-strength spring designed for pressures beyond 5,000psi (400BAR), high-quality materials, and a highly visible, luminescent face make this a common favorite among divers in all environments. Pick from our Standard or Stage pressure gauges.
The weight and size of our Standard SPG gauge make it well suited as a primary SPG; the large, clear display is easy to read in all diving conditions.
Key Features of the Standard SPG

* Calibrated for BAR (0-400) or PSI (0-5500)
* Nickel-plated brass with mineral glass lens

Technical divers with multiple stage/deco cylinders often prefer a small, light SPG; our Stage pressure gauge is perfect for just such an application.
Key Features of the Stage SPG

* Slightly smaller than our standard SPG
* Light weight helps balance stage/deco bottles
* Two models calibrated either for BAR (0-360) or PSI (0-5000)
* Nickel-plated brass with acrylic lens
