Cool idea @jefflombardo. Any specific metal detectors you have in mind that may be a good fit for the F1?
That's an excellent idea..!
This one has nice features: https://www.engadget.com/2017/01/03/powerray-underwater-fishing-robot/
Saw that in another place also. I posted it in use cases

@ocram and @jefflombardo, isn't it incredible what drone technology is being applied to? The PowerRay looks like a pretty slick machine; I'll be interested to hear more about it once it's out in the field. Based on some ideas we've had here on the forum, it wouldn't be that hard to emulate a similar setup using the F1!
This feeding frenzy of potential F1 applications is amazing!
