Reverse Discrimination.

The method of "Reverse Discrimination" was brought to my attention by Gary Keithline of Find Electronics, who operates all the great Metal Detecting forums at findmall.com.
"Reverse Discrimination" is a method for the times when you want to concentrate on those really deep signals in search of those really deep coins while hunting with the Minelab Sovereign. It is an excellent method when hunting those "hunted out" sites that contain a minimum of trash.. I am sure that it is an excellent method for beach hunting also.

Step 1. Begin detecting in the all metal mode. Concentrate on those soft, faint, repeatable signals that indicate a deeper target. It is important to swing the coil slowly so that you do not miss those signals that so many others overlook. In addition to the normal level swing, just sort of poke the coil here and there making sure that you cover the ground as thoroughly as possible.
Step 2 When you finally hear one of those faint, repeatable signals, you want to immediately switch to "Discriminate Mode." The key is to ignore any meter if you are using one and listen for the Threshold Sound. Recheck the target and listen carefully.

Step 3 When you pass over the target and the Threshold "Nulls" (goes silent), this indicates that the target is ferrous. If you are concentrating of finding coins then do NOT dig this signal.

Step 4 However, if you pass over the target and the Threshold does NOT "Null", then it should be considered a "Good" target. Dig this target regardless of the meter reading. Many times the target will give you a tone in "disc mode" but sometimes it will not. Therefore concentrating on the Threshold Sound is the key.

You will dig a few more nails with this method because many time you are at the extreme range of the sovereign’s coil range. However, the number of deep coins you will find will amaze you. Many of these coins will not be old coins but newer coins (1900s) which are out of the range of normal detectors!

If you need further clarification, please email me and I will be glad to assist you in any way I can! The very best of luck to you!
