Halcyon Gauge (SPG)

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 make this a common favorite among divers in all environments. Pick from our Master Diver or Stage Pressure Gauges.

The weight and size of our Master Diver 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 Master SPG:

• Calibrated for bar (0-360) or psi (0-5500)
• Nickel-plated brass with mineral glass lens
• Size - Gauge Face 2"

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 (0-400) or psi (0-5000)
• Nickel-plated brass with acrylic lens
• Size - Gauge Face 1 3/4"
