Gregg,
I think it was meant iLevel, which is another ADS-B device with an AHRS. Levil Aviation makes a Levil AHRS and an iLevel ADSB/AHRS. You would not need both of these units, but one might use a SkyRadar or non-AHRS ADS-B device with the Levil AHRS. Sorry for any confusion. Levil and iLevil looks very close.
Yes, the Levil will connect to the iFly 720 via Wi-Fi, not Bluetooth.
I woudl suggest that you would want to compare the iLevel with the Clarity SV. We are testing the iLevil now and will have a update shortly. It's a very tight package that offers the abilitiy to connect an external antenna and also has a solar cell for trickle charging the unit. Again, another very impressive unit.
It's a very dynamic market and one would really need to look at all the features each of these companies offer on thier websites and match that up with your individual needs. Don't buy more or something you will never use. The additional features are only worth it if you're going to get good use of them. I hope this helps.
