Maybe I should start off with Pokemon Go first to get warmed up. Similar concept where Fenn wants people to bring out their inner Indiana Jones. Instead of giving away a fortune, the makers of Pokemon Go were trying to make one.
If the Fenn-treasure-seeker ground penetrating radar drone teams do materialize, they will almost certainly locate archeological sites, which is pretty cool. The algorithms ought to also pick up petroglyphs while searching for blazes.
