The weight and size of the 52mm Halcyon Standard SPG make it well-suited as a primary pressure gauge. The clear display is easy to read in all diving conditions.
Halcyon started with an industrial-strength spring designed for pressures beyond 400BAR, high-quality materials, and a highly visible, luminescent face making this a favourite among divers.
