Drone for Farming

I have a DJI Mavic 2 Zoom, which is quite old now at this stage. I would think DJI are still the best brand. Not sure what models are about now, I would take flight times with a pinch of salt. I know they said mine should fly for 31 minutes, be very lucky to get 23 on a calm day and I'd be cutting it very fine getting back. The zoom function is helpful to be able to see into areas that you couldn't as you might lose signal descending to see something. Sheep WILL get used to a drone, and while they may run like fcuk for the first few weeks, they'll stand against it after a while and you'll be left holding your.... controller. Wind doesn't bother mine but you're not going to be using it on wet, misty, drizzly or other moisture filled days - that can be a lot of days. You will miss a lot of important things checking sheep with a drone, compared to walking through them. About the best that it'll do is tell you where they are, if they're caught in a fence, if they have very obvious maggots, if they have a lamb and other very obvious stuff like that.
