Just for clarification. There are 3 models of the SkyGuardTWX Vision-Pro. None of which will communicate Bluetooth or Wi-Fi and Serial at the same time. It's and either or.
- Serial Out only $1299 - This model does not have Wi-Fi and transmits 978UAT and receives on both the 978/1090ES.
- Wi-Fi Model $1399 - This model is Wi-Fi only, no Serial. Also transmits 978UAT and receives on both the 978/1090ES.
- AHRS Model $1799 - This model is Wi-Fi only, no serial. Transmits 978UAT but only receives on the 978, no 1090ES.
Additionally, Cobra is correct these are not TSO or FAA certified yet for the 2020 Mandate, but according to the ADS-B rule, they do not have to be certified until 2020, at which time the ADS-B Mandate is active and it has to be certified or the transmitter needs to be turned off. Keep in mind it is only the Transmitter, GPS and Install that needs the certification. Nothing with the receiver, AHRS or receive antennas needs to be certified for 2020.
SkyGuardTWX is currently testing for the 2020 certification. I'm positive there will be changes needed to Mounting, Antennas, Power connection, etc for the certification. There is no way the FAA is going to certify a portable ADS-B with suction cup antennas. This was done to get them into the field as part of the testing process. Don at SkyGuardTWX has indicated that he plans to make available a "retro" or "certification" kits to meet certification needs. The details and cost of those are still unknown as it just to early in the process.
I personally went with the Vision-Pro with the "I get Full ADS-B Weather and Traffic till 2020, then if it is not certified, I still have a ADS-B Receiver". Many of the ADS-B Out (ie 1090ES or BK KT74) Certified options do not have a receiver, so you are only providing, not receiving. If I'm going to be force to provide my position to the FAA, I sure want to be able to see what everyone else it also providing as well. Just my two cents.
