This is pretty cool. I originally bought this for a wedding so I could let the bouquet fall from the sky. It was cool, but I didn't know what I was going to do with it after running this query, so I looked it up. People actually fish with it. Instead of throwing, they fly it out and throw the line away from where you are. It's pretty cool. I tried it and was impressed. I didn't catch anything but it's cool. It must have been my bait. I think it's amazing stuff. I plan to use it again. Looks like I could do other things with it. It's pretty easy to use. It uses the light below to open the claw that you control on the controller.
