Re: What is a "Relic Machine"?
Dear Lash;
If you want a REAL relic machine then I can not recommend the Minelab SD2100 highly enough, my friend. Not only does the SD2100 have incredible depth, it also can find pottery shards (no kidding) old campfires and even glass! The reason why I know the SD2100 can locate all of these items is because I have located them whilst using mine, and more than just once. I have an SD2100v2 and it's simply AWESOME!
The only two real downsides to the SD2100 is the price and the fact there it has no discrimination, which coupled with it's extreme depth means you will be digging a LOT of junk if you are detecting in a trashy area.
I also have a Minelab GP-3000 and it's actually a better relic detector than the SD-2100 BUT it's a more expensive machine and more complicated to use. For a beginning relic hunter the SD2100 is a great unit, as it has only a few, very easy to understand controls, and the settings can be learned by anyone in an afternoon or two.
For examples of various depths, I've located old steel beer cans at 16" with my SD2100 and a Coiltek 18" mono coil, bottle caps at a good foot and bits of wire at 14" or more. The best depth that I've achieved thus far has been an old rusted piece of flat iron at 20 inches. The SD2100 is also a superb gold finding machine! I've located tiny gold nuggets of less than 0.2 grams at over 12" depth and larger species at 15 to 16" depth!
