Hi friends this is arvind frm Andhra Pradesh. Mera friend ke ghar mein ek under ground treasure (nidhi) hai hum log usse bahar nikalne ke kaam kar rahe hai. Lekin 5feet khod ne baad usme se ek power nikal raha hai koi metal se kaam nahi chal raha hai. Torch test karke dekhe tho bulb fail (11.inch) hogaya 1 nahi 4 bulb test karchuke hai. Koi aisa company hai andar ka power ka suck karsakte. This is my mail id RPGUNTUR@YAHOO.COM PLZ REPLY
