There’s a new video game being released soon called Halo 3, and there are commercials for it ever 15 minutes. The game has nothing to do with this post except that the commercials made me think about the halo effect and metal detecting.
If you’re new to metal detecting, you may have buried a few coins to test how deep your metal detector would work, and you may have been disappointed. The reason new coins are so difficult to detect is because of the absence of the, “halo effect.” The most basic definition of the halo effect is that the coins become electrically more associated with surrounding earth materials and the molecules of the metal begin to “leak” into the surrounding soil.
Sergei from metaldetectingworld.com has a great description of the Halo Effect and how it relates to constructing a test garden. If you’re just starting out in the world of treasure hunting, make sure you visit his site. His site gives advice and tips for fans of metal detecting.
