This is a very engrossing show and a serious attempt to unearth some of Yamashita's gold in the Philippines. But in one episode they missed the boat completely when they dug down to a concrete slab that was actually the top of a treasure vault. Unfortunately they went no further, but if that had read Sterling & Peggy Seagrave's "Gold Warriors" they would have realized that they were on the top of a gold vault--the top probably four feet thick. Hope they find some.
