You can use an external (bluetooth) GPS with a wifi only tablet. There are many threads on the topic. It seems that the most talked about here on the forum are Bad Elf, Dual and the Garmin GLO. Just search and you will see
plenty to read for research if you want to look into that option.
One thing to watch for: iOS 8.3 broke the ability for an external GPS to transfer data. It was fixed with iOS 8.4 and later, and still works in iOS 8.2 and earlier. It is only iOS 8.3 with the issue.
Also, Android tablets almost always have built in GPS so they are another option to consider. I use an
Air 2 as you can see in my signature below.
Cheers!
