Dear Mr.Bhatnagar, I am presently staying at chittagong in Bangladesh. I was handling a RP Cylinder (extracted from Pillar), already tested and primary-packed by a European Buyer. The owner suddenly died of shock after seeing the huge amount given to him in cash by the buyer as booking money. The incident caused a blunder of losi8ng the product as he (the deceased) hid it underground for safety. We know the area where he hid it but can not locate the exact spot to take that out. Hence, can you please help us with a device RP DETECTOR or anything alike to find out the hiding spot? We would like to buy that device or share some amount for the device after the exchange is complete. Please inform us if anything alike is in your knowledge. Thanks and warm regards. Derek
