Every diver needs a reliable way to check their air supply, and the SEAC Pressure Gauge is a trusted backup or primary option. This is a classic analog SPG (Submersible Pressure Gauge) that connects to your regulator's first stage with a high-pressure hose (included – it's about 31 inches/800mm long). It has a clear, easy-to-read dial with a luminescent face and markings, so you can check your tank pressure even in low light. The scale goes up to 225 feet/70 meters of equivalent pressure. The case is made from tough, chromium-plated brass, and the lens is high-resistance polycarbonate, so it can handle the rigors of diving. Its compact size makes it perfect for mounting on your wrist (with an optional boot) or clipping it to your console. It's an essential piece of safety gear, giving you peace of mind so you always know how much air you have left. Whether you're backing up an air-integrated computer or need a simple, dependable gauge, this SEAC model is a solid choice.
