Prisma Air Gauge Vs Longacre Digital Pro

Is the Prisma air gauge really worth it compared to The pro Digital for almost half the price. Was just about to order the prisma but wanted to see what others say about it?

I have had my Prisma for like a decade and it has never let me down. Still super accurate.


I bought a Prisma this year and checked it against my 7 year old Longacre. They read the same down to the tenth. Not an exhaustive test or anything, but it gave me back some confidence in my old gauge. For now I am sticking with my old gauge and using the Prisma as a backup/benchmark…

If I were in a position to buy a new gauge I’d pretty easily make the case for the Prisma, however I’ve my longacre digital for over 10 years and it’s still accurate and does what I need it to do.

Just outta curiousity…

What kind of application needs 60k psi?


Maybe something like a water jet I’m guessing

Thanks for all the replies, I ended up getting the prisma. I already learned a lot about my air pressures with it yesterday.
