I have the Geovid 3200.com and they are amazing. Not sure on the question tho. I bet it would have to be Bluetooth connected just like it does when you are uploading your ballistics drops from the app. The binoculars have their own weather data like temperature and barometric pressure so unless you are trying to take wind readings all the time, I don't see why you'd want a kestrel hooked up. The beauty of having a high end RF binocular like the 3200.com is that you don't need to carry multiple units with you to make a long range shot.
I had some questions when I first got mine and called Leica customer service. They were great at answering everything for me.
