Fisher GEMINI-3 warranty Depth, Treasure Hunters’ Code Of Ethics

TREASURE HUNTERS’ CODE OF ETHICS

LETS PRESERVE OUR TREASURED SPORT!

   Laws governing the use of metal detectors are becoming more and more common. In many countries, the use of metal detectors is illegal or severely restricted. Don’t let this happen in your area.

ALWAYS get permission to hunt on private property. ALWAYS leave a site cleaner than you found it. Take at least some trash with you or, if you can, take it all.

ALWAYS fill in your holes neatly whether you’re in a city park or remote wildernessness. Leave the land as it was before you disturbed it.

ALWAYS obey all laws relating to Treasure Hunting.

ALWAYS return valuable property if you can locate the original

owner.

ALWAYS do whatever you can to give the hobby of Treasure Hunting the good image it needs and deserves.

DEPTH

   The GEMINI-3 was designed to locate large, deep objects such as an iron chest, pipe or an ore vein. It will not detect small coin- sized objects. A quart jar full of coins, however, may be detected one-to-three feet deep. A 55-gallon drum may be detected as deep as 10 feet. A very large object, like an automobile, may be detected at 20 feet or more.

   The ability of the GEMINI-3 to detect objects at various depths depends on several factors:

1.Ground Mineralization: The penetrating power of the GEMINI-3 is adversely affected by the presence of magnetite (a black iron oxide) and wet conductive mineral salts. For example, an object that can be detected at 15 feet in neutral ground may be detected no deeper than 5 feet in highly mineralized ground.

2.Size and Depth of Object: A 4-inch diameter target will produce signal 64 times stronger than a similar 1-inch diameter target at the same depth. An object 1-foot underground will produce a signal 4,000 times greater than the object 4 feet deep.

3.Length of Time Object is Buried: An object that has been buried for a long time may be easier to detect than a newly buried object. Rust and other oxides as well as mineralization caused by the interaction of the metal with soil chemicals are good conductors and aid detection.

4.Shape of an Object: Ring or looped shaped objects lying flat produce the best results. Flat or dish shaped targets are also easy to detect. Rod shaped objects, especially when scanned on end, are very difficult to detect.

5.Operator Skill: Probably the most important factor of all, practice over known buried targets is essential.
