Gauges






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

Oops - double post.

I thought Termo made pretty much all SPGs at one point, is that still the case?
I assumed the moisture was from lazy equipment rinsing, maybe it isn't.

Regardless, can I get the moisture out of there when we have another sunny day, or is it stuck there? Is it possible to flood the gauge with fresh water first to remove the salt or will that permanently flood and destroy my gauge?

I am not familiar with Halcyon SPGs but my older Scubapro SPGs can be disassembled (the collar on the face unscrews) and cleaned. That face is sealed with a replaceable o-ring. My understanding is that some modern gauges can be similarly disassembled while others can not.

If a leaking SPG (visible water inside) can not be disassembled, cleaned, and resealed; it is probably just a matter of time before it will fail or accuracy will suffer.

BTW, the pictures of "H" SPG don't seem to show any knurling on the retaining ring which is probably a good indicator they do not unscrew.

Halcyon pressure gauges are as reliable as they are accurate.

If that means they're as accurate as they are reliable I might as well dive without one.
