Of all the compact handheld tyre pressure gauges on test, this one is easiest to understand. Four labelled buttons clearly explain each function, so you can see how to switch on the gauge, choose the correct unit of measurement and take a reading. A button labelled ‘LIGHT’ switches on the backlight upon the first press, then a blue torch (keeping the backlight on as well), and switches both of them off with a third press. A ‘MODE’ button switches between pressure readings and a millimetre scale for a digital tread depth function. At first, this had us puzzled, until we spotted a plastic tag on the back of the gauge, which is the slider for the tread depth gauge that protrudes out of the top of the device. As all the rest of our gauges on test produce analogue readings for tread depth, this is seemingly the most accurate and easiest to read. Overall, this gauge is straightforward to use and its single CR2032 battery is simple to access and change. At times, it was difficult to locate the gauge onto the tyre valve and see the readout, but upon releasing it, the pressure reading remained displayed. Its recommended price is high compared with many of the other gauges on test, although we found one for half this cost on Amazon.
