Im using the internal antenna right now. I was going to buy the external antenna but I did not know If it was any better. As far as I can tell it is pretty accurate once it has found my location and I have never lost it once I have been found.ironsbrandon do you have an external antenna or are you just using the internal antenna?
The samsung tablets and most android tablets have built in GPS no data needed. All you need to do is have your maps downloaded ahead of time while on WIFI or data. Then they will work anywhere for mapping. The app I have found to work the best for what I need is called Back country navigator. Lots of great tutorials on youtube on how to use it.For those that are running with tablets, do you have to have the data package to do this, or are you tethering off of your phone?
