Thanks for the information. I am looking for the gold coins and buried gold
...... want gold detector for gold coin and buried gold (max depth 10 feet) ....
You still have not answered my original question. You are saying " gold coins" and " buried gold ". But this does not answer if you mean individual coins, or if you are referring to buried chests (large objects) full of gold coins. And don't say "all of the above"

Otherwise you'll need 2 different machines (lest you be beset with scores of "gotcha" downfalls).
Based on your last post, where you refer to 10 feet and treasures, I am going to assume you do
not mean individual fumble finger losses. And that you mean large treasures.
As such, do NOT not get a coin or Relic or nugget machine. Even if some of them can get a Volkswagen to 10 or more feet. Instead, get a 2-box machine. Like a whites TM-808.
The inherent advantage of a 2-box unit, is that they do not see any objects smaller than soda can sized. So you will not be bothered trying to discern Big versus small.
What about Garrett GTI 2500 Pro Package with Treasure Hound Eagle Eye?? .....
Yes, the Garrett with the option of turning it in to a 2-box, will be akin to the TM 808.
Good luck. Post pictures of show and tell.
