I have defiantly considered it for prospecting and many other options.
Looking at getting my credentials so I can do it commercially.....CASA is very very strict....But I dont think they have jurisdiction in Thailand, that's another ball game.
As with any tech, there are limits...thats why I was out flying over the bloody water, I took a risk too test the effective range, got nowhere near it, too busy water and sky wise..choppers....float planes....masts........ And I have to be able to see the bloody thing! (I have to keep a 30m distance from people, buildings and vehicles/boats etc for one example)
Apparently she is good for 1km with setup....BUT you dont want any trees or hills, buildings in way....then failsafe kicks in if she looses comms, and she will fly home and land where she started from......if you have GPS sats that is.....and you where not stupid and flew it beyond battery range to get home.
