Finderator uses the Bayesian search theory to find your lost objects.
Helped to find the crashed Air France Flight 447, a lost hydrogen bomb after Palomares B-52 crash and the nuclear submarine USS Scorpion - to name a few.
(Bayesian search theory is the application of Bayesian statistics to the search for lost objects. It gives you hints where to search depending on the probability it might be there and that the probability of successfully detecting it on this location. If you searched one location without success the probability of this location is revised and considered in the next steps.)
