Question

is there any device which can trace such hidden gold beneath earth,as i m in doubt that is some old houses there r some barried gold treasure in those,but i cant dig all houses in search of that,can i trace through some device like "METAL TRACKER"

Answer 1

No such thing as a magic "metal tracker", but there are many exploration geologists like myself who spend their careers looking for gold using a variety of simple and complex techniques including geology, geophysics, and geochemistry.  We generally restrict our work to areas with potential for 10's of millions of grams of gold, not a few flakes beneath somebody's house.
