Virtually identical to the Sealey TST/PG981 gauge and with all the same functions – even the instructions on the back of the packaging are similar. So, if your choice is narrowed down to these two models, shop around for the best price.
Laser’s gauge has a black button that operates all the functions. There are no instructions to show you how to switch between different units of measurement, but we discovered this by accident by holding down the button for a few seconds – once the readout started to flash, we could repeatedly press the button to switch between the different scales. The hose and metal attachment are straightforward to use and fit onto a tyre valve, but you have to accurately locate them to avoid air escaping. The reading on the gauge resets itself once the end of the hose is removed. There’s a useful bleed valve, which enables it to remain attached to the tyre valve and release air pressure if the tyre is over-inflated.there’s no backlight and no means of switching it off (it switches off automatically after 90 seconds), despite the instructions recommending holding down the ‘ON’ button.
It’s powered by a single CR2032 battery, accessed by undoing two crosshead screws on the back. Changing the battery is fiddly, requiring a small screwdriver.
