Is there a "GPS Locators: Comparison guide" out here?

Hmmmmmmm,

If most of those devices use 2G then they'll be useless based on Bob's post. I was ticked when they turned off the old analog system that made my old motorola flip phone and bag phones useless.
I liked analog as it was still useful on the fringe. Could discern through the static whereas digital just drops too much out. Kurt

The Bayboro field has a cell tower darn near smack in the middle. Full bars 4G. Tracking still isn't perfect.

Yes the 2G thing is an important caveat for any of the cell trackers that specifically use that. Its phase out is why I won't buy any more of these, but mine will keep working for the next several launches at least.

I was thinking something like this. It is incomplete but I am working on it between assembly steps and work.

Is this comparison table maintained by anyone?

There is some good info here.

(it's fun to call your rocket on the phone and hear it ring.)
Now that's funny!
