That's basically how mine has to be or pointed directly at the stem, from the tread of the tire. Just move it around in various ways until the horn beeps.

Exactly. I use that method for multiple tasks
My low side Schrader valve is leaking (I can see it bubbling), so I am going to replace both the low and high valve cores. There's a tool ($40) so you don't have to evacuate the system, and a valve core kit is only $15. It includes 4 valve cores, one port (in case you need it), and the caps.
One of the most common questions for DIY on the internet is "Which port is the low side? I'm surprised that both caps are black, when it would be so easy to have one side Blue and the other black or red (like the replacement caps in the kit). My wife would say having them both black is something a guy did.

Yup, that's the one I ordered:
MASTERCOOL (81490) R134A Valve Core Remover Installer
Google a bit and you can find it elsewhere, and for a little less. There is another brand that operates on the same principle. I'll try to find the video to show how easy it is to use. This is the other, similar tool, and the process is the same:One video was an AC repairman, and he said he replaces the Schrader valve cores every time he services an AC system. Funny, I'm old as dirt, have had a lot of leaking AC systems, and this is the first time I've heard about this.
