My old Silca pumps gage is down on the base where I can't read it, so I just put an index mark on it with a sharpie. I pump the rear tire to the high side of the mark and the front tire to the low side of the pump and all's good. The lens is loose so I can just set the index mark at the desired range, depending on tire/wheel set.

I've got a Bicycle Gauges Archives - Accu-Gage by G.H. Meiser (ghmeiser.com) for when I want to get fussy. In fact, a stand alone air gage is probably a good thing to have if using more than one pump to inflate tires. Compare the pressure readings of the pumps to that of the gage and find the point spread for the pressure you want. 1 pump may read 50, the other 75 and the gage 60 for the same pressure. No sense pumping to the same reading on both pumps when they're wildly different pressures.
I got a zero to 15 gauge for my fatty. It was the only solution. I pump and check it once in a while. I’ll trail ride at 10 or better, beach is 5-7 depending on the sand and some snow, 1psi. Snow is a bitch until you dial in your tires, then you take off. It’s hard to even explain but it’s dramatic. I’ll put 3psi in the tires and head out and bleed it down until works. No pump is going to give me any decent feedback at those levels...

Guys, it's gauge, not gage..

Gage is acceptable. It's quite common in the field of pressure gages/gauges.

Dwyer is one of the worlds largest Gage manufacturers.

GAGE OR GAUGE PRESSURE?
In the measurement and instrumentation literature and industry, the words gauge and gage can both be found to describe a pressure sensor or transmitter that measures relative to ambient pressure.


Penn State Engineering
Gage pressure (sometimes written as "gauge pressure") is measured relative to the local atmospheric pressure

My floor pump is 10-12 years old, on its last leg. But it has an adjustable dial with a red triangle for me to use as my “mark” of where the pressure needs to be. @velodog has a great suggestion, perhaps a white marker on the black dial to help where you need PSI for your various bikes.

I’ll also recommend a pancake compressor for your garage. It’s so nice to have, not for bikes, but for the cars/trucks and perhaps occasional air tool project. I’ve used mine for everything, and most recently seating tubeless tires on two of my bikes. It’s nice to have and it’s not really that pricey. I got one of the entry models from HD and am happy to have it, especially to keep the truck and car psi up where it needs to be.

I have a Joe Blow pump that is on its third leaking gauge assembly and I am moving on. I currently run a tubeless setup on wide rims (28mm tires) and I see this always being the case, maybe even 30s on the next bike. I also have a city bike with child seat on wider tires that also takes a lower pressure. On my road setup I inflate to 5.5bar (80PSI) and the city bike is around 60PSI.

I considered portable electric infiltrators but was off put by the nose, subpar chucks/heads, short cords and needing it charged. These seemed like they would fit best as all I ever do is top up my TL setup that loses PSI with each day it sits.

I considered a hi pressure floor pump but was reminded how small the usable PSI range is on a gauge that covers 0-130 PSI. I run 75/80PSI on my setup and gone are the days of pumping skinny rubber to 90-110psi.

I settled on a "mid-volume gravel pump" a Lezyne pump (Gravel Pro) that inflates up to 100PSI. The pump is still in transit and thus I have no initial impressions. The purchase wasn't knee jerk but I'm still thinking it over.

It occurred to me after purchase that while there is a greater usable PSI range on this pump, and it should be easier to see the exact PSI, the top shelf model has a digital gauge (crickets). It should be just as easy to hit desired PSI with any other digital gauge equipped floor pump, correct?

That only leaves the increased stroke volume as a plus over higher PSI pumps.

I enjoy paying someone else to seat TL tires and is one of the few things I go to an LBS for. 100PSI should be enough to inflate a air can to seat tires. Comments thoughts?

If you have a digital display on your pump, is this a love hate relationship? How so?
Not sure if this answers your question, but here it goes. I recently got into tubeless, head first, knowing nothing of the technique. Like you, I have an older Joe Blow (Pro). Unlike your's, the chuck on mine does not leak. The analogue gauge, is reasonable, though after recently buying a digital gauge to take with me on rides (in the event of a leak/flat) it's apparent the analogue gauge is off by a bout 5psi. Not a huge deal, but it's not accurate.

I too learned that in order to seat the tire bead on the rim, I'm either going to have to buy a dual cylinder pump, which both Lezyne and Blackburn make, or a compressor. A friend of mine who owns a bike shop "schooled me" on what I need to do for riding tubeless. He advised that I forgo the dual cylinder pump, and buy a home use compressor that will have a hundred more applications, should I want to avail myself of them, than a bike pump, which will do one thing only.
I followed his advise and bought a 2 gallon (recommended size) Makita 1HP compressor. It's the "quiet series", and it is as advertised. Works like a charm seating tubeless tires. It has two analogue gauges, one for the tank pressure and one to indicate the pressure that you are injecting into what ever it is you're working on, i.e., bike tires. I have been advised not to rely on it to check tire pressure on any type of tire, including, car, bike, etc, but to use a hand held gauge, analogue or digital.

For rides where I need to carry a pump in the event of a leak or a flat, I use a Lezyne Road Drive which will do up to 160psi. Cheers.
