agreeIt works outstandingly well! I considered using an iPad, but the majority of the brackets that hold the device also block the view of the controller. They’re also unwieldy. I also considered using an old iPhone 5, but it won’t run the GO4 software. The 7+ was the perfect compromise
One problem that you will encounter no matter what phone that you use, will be glare from the sun. Phones or iPads just aren't designed for outdoor use, and will be overpowered by the sun. You'll have two choices.
1. Find a shady spot somewhere to minimize the sunlight.
2. Use some kind of a shade to screen the viewing device.
I've had minimal success with the shades, so I look for a place to stand that's protected. In an emergency, I've used the landing pad carrying bag with a little success, but the commercial shades have not worked for me.
Now, has anyone else found a better solution?
