Halcyon Master SPG - Dual Scale (PSI & BAR)
By Halcyon Manufacturing | 2" Technical Chrome-Plated Brass Submersible Pressure Gauge
Built with a rugged chrome-plated brass housing and a scratch-resistant tempered glass lens, the Halcyon Master SPG is engineered to withstand the most demanding technical and cold-water diving conditions. Featuring a clear, dual-scale face displaying both PSI and BAR simultaneously, it offers precise pressure readings at a glance—making it the ideal instrument for traveling divers and technical teams operating across mixed systems.
High-Contrast White-on-Black Display & Red Warning Zone
A preferred choice for stage and decompression cylinders, the Master SPG features an inverted white-on-black display that optimizes readability in dim cave passages, deep wrecks, and murky water. A vivid red zone highlight and high-visibility needle ensure critical low-pressure alerts are impossible to miss.
