How does that Phantom 3 handle the wind? Do you know what mph the wind can get to before you don't send it out? I've wanted one for the cattle thing since I first saw one, just can't justify the expense if conditions prohibit it's use most of the time.
We have 1200 acres and use a DJI Phantom 3 to check cows when the weather is bad or it's muddy and we're expecting cows to calf, etc. Has already saved us once when we spotted a cow having problems calving and was on the back side of the place. The Phantom 3 is loud and I can't see a deer staying in one place for very long with that thing buzzing overhead. By law, you can only fly up to 400' in altitude but you can still hear it. Hogs, on the other hand, are a different story. I have used it to locate them and scout where they are staying on our property. They usually scatter when you get down close and it's fun chasing them. We fly ours with a ipad and even with the bigger screen it's still hard to see sometimes especially when the sun if bright. It's very hard to pick out something as small as a hog or deer too. They almost have to be moving for you to see them. The cameras on these drones are so wide angle that it makes everything appear to be out a lot further than it really is and there is no zoom feature. So to see something up close you have to get really close to it. By that time, you've ran it off.
