So some of you know I have a company that locates missing bodies. I have a trained bloodhound who can find a human bone in a field in just a minute or two. It rained her myself and it took every day for a year. Now I am certain I could train a dog to find anything. They don't care what they are looking for as long as they get a reward. They nose on a dog is able to separate smells and you could train a dog to locate any "treasure" you like.
Seems like a way better system than some LRL with a calculator glued on top. You still could glue a calculator to the dog if you wanted....
