20% for giving me help.

[the lord of the gold]

Dear
As you know the Ottoman Empire (Turks) who ruled the Middle East and the Arabian Peninsula, so there are a lot of gold funds, which were buried when they came out after the wars led by Lawrence British intelligence agent. Note that these funds are made with wood.
I can identify targets accurately through the signals, but I am not sure that the target is an underground depth of 2 - 3 meters, so advise me which device effectively can give me signals that the target exists, promising 20% ​​of the target value.
Regards
