Sam,
Yes, you can connect to the SkyGuard with an iPad. However Foreflight will not support this product, they made the decision to only work with one ADSB device, the Stratus. (And Stratus only works with Foreflight).
If you are considering an iPad, keep an eye on our website. I'm going to post some information soon that just may be of interest to you.
Thanks,
Walter
