Having to hunt for an SPG-equipped regulator when trying to determine whether a set of tanks are sufficiently full can be a pain in the butt. That's why it helps to have a simple, easy-to-use check gauge handy. Unfortunately, most check gauges are equipped with standard yoke connectors--which means that, when you want to check tank pressure on a set of DIN-equipped cylinders, you have to take time to hunt for an additional fitting.

Fortunately, Dive Rite's new Check Gauge reflects our commitment to the DIN standard, and comes standard with a DIN connector. (It you have to check the occasional standard tank, just spin on a Dive Rite RG1225 DIN-to-Yoke Adapter.$ 44.00

The new Check Gauge is made from high-quality machined brass, and provides readings in both imperial and metric measurements. As an added bonus, you don't have to fiddle with easily-lost bleed screws. Just press a spring-loaded button on the side of the check gauge, and the unit drains within a fraction of a second.
