junaidkhank06: For a lunch-box sized object "filled with gold" versus "filled with silver", versus "filled with bronze", will all be detected at the same depths, when using the TM 808. It does not go deeper for one metal versus another.
And .... I hate to be a kill-joy, but .... be prepared that perhaps gold statues, and caches of gold and silver might not be "popping out of the ground" there. What I mean is, that treasure stories are a dime-a-dozen. And sometimes these legends (and stories of supposed finds) are ... uh .... just legends. Or to the extent that , sure, a cache or statue gets found somewhere, doesn't mean that "the landscape is littered with them" .
I have hunted certain countries where treasure legends abound. Everyone is convinced that "certain treasures" await them. If *only* they can go '3 meters deep'. And yes, like your situation, they all have colorful stories of past treasures found. But I discovered that ... when trying to get to the bottom of the past-stories, they turn out to evaporate. Turns out no one ever saw it. But only heard it from a person, who heard it from a person, who heard it from a person, who.... well, you get the picture. And when you dig deeper into the stories of why they think a treasure is in a certain cave or ruin, it's the same thing: telephone game gone awry.
So just be prepared that, treasure stories are easy to believe in (no one wants to be "left out"). I/we hope this isn't the case where you're at. But .... just sayin' .....
