Any significant advantage to digital pressure guage versus pencil type?

In one word - accuracy and it is not the pencil type that is most accurate.

I use both. Digital for home (work) and pencil on the road. Pencil takes up no real space and accuracy is good enough.

This!

Presta, dial, Zefal, went on my last bike tour..... no batteries needed..

I'm not aware of a pencil gauge that'll read up to 100 psi and work on Presta rims. The Zefal dial gauge [MENTION=197614]fietsbob[/MENTION] referenced works well, though.


For that matter, so does my thumb.

Where'd the Presta requirement come from?

I have a Kingsbridge gauge that fits only presta and goes well above 100 psi. But it's out of production.

A vintage standalone presta valve pressure gauge

OP didn't specify valve type, or pressure requirement, so I made both up since they're what I need to measure the pressure on my tires.

Storage space is primary for me. Here's a pencil gauge rated to 120 lbs. You can calibrate it at home against a digital gauge. Add a Presta to Schrader screw on converter, also tiny, and your good to go even with Presta valves.

I used and still use the AccuGage for presta and another for Schrader, I did try the Topeak D2 and it just didn't work well for me and it seemed like when I really needed it the battery was always dead.

The AccuGage is pretty small, easily fits in a small saddle bag, Presta, Schrader

I don't believe in pressure gauges for bikes. On the road my thumb is accurate enough. At home I pump up the tires at least once a week and use the guage on the pump

Wait a sec, it would seem you DO believe in gauges for bikes.

Digital pressure gauge does more exact measurement AND the result is shown more accurate and easier to read.
Disadvantage is the need for an small battery cell.
So at home digital gauges are good, on the road analog measurement can be better.
