icecoldgin you really are a bright man (just like lee82gx) to let me know this info! Thank you.
The way I interpret this is that the Mavic Air 2 costs a bit less than the Mavic 2 zoom, but also gives a 4 x zoom, and their range in CE will both be the same ie. 6km. Not possible to hack at this stage to increase the range versus buying the Mavic Pro 1 which lee82gx said can be boosted for free to 10km, but can only fly a total distance of 13 km (unlike the Air 2 and 2 Zoom that does 18km), therefore needs a battery extender and only has 2 x zoom. I suspect it would be highly complex to purchase a zoom camera to attach to the Pro 1.So it seems one might have to settle for the cheaper Air 2 with a 6km range with a 4xzoom. I am not sure how much one can see when reaching the 6km limit, then zooming x 4 to see the rest of the land on the farm over an additional 4km with the 4 x zoom (whilst 100 meters in the air). Nobody ever makes videos on youtube like this.
Any thoughts or ideas or suggestions from all the experienced, and most helpful members here?
Thank you Thomas B, Icecoldgin and of course lee82gx and everyone else, and merry Christmas.
Best wishes
