Metal-Detecting R/C Car
Who knows how effective this tiny metal-detecting R/C car might really be, but it certainly makes holding the sensor just above the ground very simple, even as it limits the amount of places you might be able to use it. But even if you were just running it through the grass at a local park picking up loose change and used needles it would be more fun than a traditional metal-detecting wand.
It's £50 and includes real "gold coin replicas."
I have a feeling my father's slight preoccupation with South Florida treasure hunting may result in something similar as he enters his later years, bombing down the beaches in a metal-detecting wheelchair.

THESULLIV beat me to it. These sound like a cheap substitute for expensive robots if they are any good, and from the looks of it they aren't heavy enough to actually trigger the mines.
