Thanks for the clarification on range for the DJI ... 300 yards is a lot better than 300 feet.

Another drawback is that the copters are really only useful in calm stable air ... Definitely not storms, strong winds, and night conditions (needs low light camera). So that weather limitation is significant. But the DJI looks to be very portable and could be launched from whatever position a SAR team member was located. This could really make searches of off- trail locations an easier proposition.

I like the idea of overflights with an HD camera a lot. As in ... Miles of video footage. That requires a different type of drone. But the videos could be sent to observers in their homes for scanning. So this type of crowdsourcing has excellent potential.
