The Highland Thin-Line Submersible Pressure Gauge (SPG) provides a widely visible 240º view of your air pressure, from 0 to 5000 psi. This SPG is sophisticated and durable with its nickel-plated brass housing and its clear lexan len. When diving, you want a clear understanding of how many pounds per square inch (psi) of air you have and this SPG will keep you accurately updated every step of the way. Even in low-light scenarios, you can clearly determine your air pressure with its luminescent gauge face. With an air spool and Viton o-rings included, all that is left to do is to connect the Highland Thin-Line SPG to a high-pressure hose (not included) and you are ready to dive!
