How do I read the Quick View gauge?

Press the chuck squarely onto the valve stem and the internal scale slides out to show the pressure. Read the number at the edge of the barrel, then push the scale back in before the next check.

Does it need batteries?

No. It is fully mechanical, so it works whenever you need it and never needs charging.

What pressure range does it cover?

It reads 10 to 50 PSI, which covers most passenger car, trailer and bicycle tires. It is not intended for high-pressure truck or performance tires above 50 PSI.

Is it as accurate as a digital gauge?

Pencil gauges are typically less precise than digital ones. The coarse scale makes it fine for routine checks, but use a digital gauge when you need exact figures.

Can I let air out with it?

No. It only reads pressure; there is no bleed button, so release air at the valve separately if you overinflate.

Where should I keep it?

Its aluminum body and compact size suit a glovebox, door pocket or toolbox. Keep the chuck protected so the zinc alloy head does not get knocked out of shape.
