Can you tell the difference between 15psi and 17psi with a simple finger squeeze? No you can't, but Blackburn's digital gauge can.
Swivel Head - It's hard enough getting the perfect tire pressure without craning your neck to see what the gauge says. The swivel head makes it visible at all angles
Air Bleed Button - Button on the pump head micro-adjusts pressure
Backlit Display - The backlit screen is easy to see whether checking tires on a dawn raid or just fumbling around in the back of the garage
Audible Chime - An audible chime lets you know when you're powered on, and when pressure is registered
