recovering lost lures is a great idea
Although this could be a tough project. Maybe impossible?
I always see people walking around beaches with metal detectors.
Maybe looking for lures? Or some other treasures.
But how would you get a lure that you lost in 10 meter deep water without diving equipment and very sharp eyes
Maybe a lure with a little motor and microchip, so that it can swim back on its own. Although it might then be fishing on its own and never make it back.
If people concentrated on the really important things in life, there'd be a shortage of fishing poles.
