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. Pick from our Standard or Stage pressure gauges.
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.
