Caution: This SPG is popular with tec divers due to its lighter weight and thinner profile (as compared to the heavier and bulkier brass-and-glass model). However, at depths beyond 50 m (165 ft) the increased ambient pressure may bend this SPG’s polycarbonate face and push it inwards. While this does not flood or damage the SPG, it may prevent the needle from moving. Obviously, this may significantly affect the SPG’s accuracy.

Once the diver ascends and the ambient pressure decreases, the polycarbonate face returns to its normal curvature and the needle is free to move. Since tec divers typically use this SPG on deco gas cylinders (which are breathed at shallower depths), the potential inaccuracy at depths deeper than 50 m (165 ft) does not usually pose a problem. However, if your dive profile requires accurate gas pressure measurements at depths deeper than 50 m (165 ft), then XR Scuba recommends you use a traditional brass-and-glass gauge.
