From Blackburn: 

You've paid for full suspension, now it's time to use all of it. When the trail gets steep and rough, can you tell the difference between 150psi and 170psi by pressing down on your saddle? No, you can't, and neither can we. The Honest Digital Shock Gauge can.

We've been big fans of this digital shock pump for a long while at Somercycle Bike Shop due to its reliability and accuracy and ease of use. Once you've went digital for a shock pump, you won't want to go back!
