My Thoughts After Field Testing
Both of these devices are the best satellite communicators on the market when you look at them only for their communication features.
If you’re interested in navigating or seeing quality maps, than neither of these devices would be right for you.
These devices are best for people that already have a way to navigate or don’t need to navigate. Again, they are extremely powerful communicators and should be seen that way, in my opinion.

I would like to know that even though you pair both units using Bluetooth, they will not augment the features of GAIA. Does the pairing augment the GPS in the iPhone?
Since the GPS on an iPhone 11 is not that great I want to make sure that using GAIA and Zoleo or Inreach will make the tracking and position more accurate. Please clarify. Respectfully, Bert
I have not done an in-depth test on this, other than to say, I have checked the accuracy many times using my Garmin inReach devices by themselves and also a lot when paired to my iPhone, using the Explore App. The accuracy has always looked similar, but I will add this to my list to test further.
Thanks for bringing this up.
