Yeah Tom, they have an awful sound...can be in foil or high iron,...really an awful sound, so it comes down to focusing on those signals in a likely chain losing place like the soccerfield you mentioned, around a basketball court, along the edge of parking lots where the snow gets pushed outside those wedding reception rental halls...especially out back where the smokers go and a fight would break out...even in some totlots...where the guys go at night...in a park near the bb court if you can find one...a totlot with a bb court that has night games going on is a hotspot.
O course swimming areas...but not all of them are good for chains...if you have a place where a lot of drinking goes on, and a big shallow flat with maybe a foot of water in it..thats where the guys play football in the water and show off...
The gold chain signals are not strong and dont hold when you lift the coil very far, if that helps...and the detector has a hard time figuring out the links and jumping around in a scattered signal you know?
Men that wear big gold chains have about one thing on their mind...its not tough to find the spot where that one thing happened outdoors, but is is tough to find that chain...condom wrappers in the private areas of any place are about the best signal you can get to have a chance for a chain...you will find the medallions, and if the bale isnt broke, the chain is nearby, but if its a small one, it may not register on your machine unless you hit the clasp..tiny little peep if anything...good thing is they are out there, and with such a bad signal, missed by coils...
