Why make a tire pressure gauge that needs batteries? Oh just what I want, to pull my bulky ass tire gauge out of my glove compartment and find it’s got corroded dead ass batteries cause it’s been sitting in there for a year untouched.
But it’s definitely a thing that exists. I, unfortunately, got one as a birthday present once, way back when. Used it maybe once or twice, then went back to a normal slide gauge and haven’t touched it since.
Consistency. You can take 3 readings in a row with that stick and get 3 wildly different results. I have a $20 digital one from decades ago that gives me the same reading within 5kPa on each try.
I have one of those in my glovebox. I think I bought it in 2003. My 2003 manual jap econobox has no need for TPMS. If a tyre is 30kPa too low, you can feel it.
Allow me to present this abomination:

Beats me.

I wanted to upvote you for pointing out this Satanic instrument but I also don’t want an upvote that close to something so wrong.

The battery died in mine.
