Mini SPG Button Gauge
The Mini SPG Button Gauge is generally used on argon tanks, or for sidemount divers who are using it as a backup while using their sidemount regulators with transmitters. The Mini SPG Button Gauge can be mounted directly on first stages of your regulators or with a short HP Hose as well. The Mini SPG Button Gauge is rated up to 350 Bars, with a one inch (1″) face diameter. There are three color zones, separated into Dark green (safe zone), Yellow Zone (Time to End Dive), and red zone (Critically Low on end).
Please do not purchase the Mini SPG Button Gauge, as your primary gauge. It was NEVER INTENDED for that use. It is only used as a backup.
