This epic tale is demonstrative of a great community effort…reminds me of one of the first threads I read on here shortly after joining (Hello from Portsmouth, Dec 2021 - Help needed to locate lost drone)
This is the downside of the Mini 2 isn’t it…though of course there’s a finite distance, being <249g it’s going to be carried by the wind that much further than a bigger drone, so the search area is that much bigger.
I really do hope Chris that you find it soon, what crazy conditions to be searching in though. I don’t suppose they could be much worse, other than if it was snowing, with the snow burying the drone! Keeping my fingers well and truly crossed for you
