The Razor SPG Bar Complete Side Mount Set is easy to read, and highly visible even in low visibility situations. This is due to the black dial background, while the needle and gas measurements are illuminated. This set of Side Mount Diving Pressure Gauge reads from 0 to 350 Bar, 

The Razor SPG Bar Complete Side Mount Set is designed specifically for both technical and cave divers, this diving pressure gauge is double chrome mirror plate treated. This allows the case to both look good, and maximum protection against corrosions. Comes with 2 x Rubber HP Hose that is Made in Italy.

The brass housing with tempered glass allows extreme durability. The copper beryllium bourdon tube mechanism never goes out of calibration, even with hard shock. (We still need to make an effort to protect our SPG when diving.)
