Scuba diving gauges or Submersible Pressure Gauges (SPGs) are attached to the dive regulator to monitor the air pressure remaining in the diver’s tank. It is essential for the diver to be able to easily read at a glance the BAR remaining in their tank. If you purchase a full set of regulators including an SPG from Underwater Sports, we will assemble and test the set for you prior to shipping.
