The memory function automatically saves the pressure unit to reduce the operation hassles.

The instructions provided are very minimal, overly pictorial and not entirely accurate. The battery protector for example required complete (and fiddly) removal of the button cells to access, contrary to the instructions. The Ring Automotive RTG4 is a great option for anyone who wants a reliable and easy-to-use tyre pressure gauge. It is small and compact, making it easy to carry with you, and it has a variety of features that make it a versatile tool.

EASY TO USE: Press the side button to turn on/change the unit, 2s long press or automatically 30s to shut-off. Great gifts for all drivers.
