Within the past few months, I bought the garmin glo2 thinking “Two devices is twice what I’ll ever need.”
I can say that the Glo2 does not play well with an iPhone 11 and an iPad mini at the same time. Both disconnect for no apparent reason. I did test the glo2 with two iPads, and it seemed to work fine. I’m not sure if it’s because the iPads are Wi-Fi only, or what, but I figured it’d be nice to have the more accurate data on my iPhone too. Except - I haven’t yet been able to get the altitude to read what it should be.
My son bought the Dual Xgps160, and he says he hasn’t had the issues I’ve had with the garmin. Which is too bad, because I like the more subtle appearance of the garmin.
I don’t really need to feed multiple devices with the garmin, so I’ll stick with it for now.
For what it’s worth, my son has a garmin inreach mini, and he said it doesn’t support Gaia, only the garmin app. I can’t confirm because I haven’t tried.
