Discrimination

#1 One of the first questions that get asked about this machine is if it will be able to discriminate pull tabs from gold rings. The answer might not be that easy. First of all keep in mind two different things. One is that the Explorer looks at a target two different ways It looks at the targets conductivity as do most other VLF detectors we are use to using AND it looks at the ferrous properties of the target. This gives us another "dimension" to evaluate the target with which we have never had before. The second thing to keep in mind is that the Explorer has the capability to "notch" or "discriminate" tighter than any other detector we have used before. Between those two things, once you have mastered them, the Minelab explorer has the CAPABILITY to be able to discriminate MOST common pull tabs while still picking up MOST gold rings and pendants.

#2 Here is a quick hint for all of you that are out there trying to "teach" the machine to discriminate pull tabs and still pick up gold and nickels. When you are in the learn mode ensure that you are using the SMALL cursor. If you use the medium or large you will find that you will loose all your nickels and lot of your gold rings when you discriminate out your tabs but this will not happen if you teach it with the small cursor. BUT, if you attempt to discriminate ALL the different pull tabs you have found you will find that you will loose gold and nickels regardless. Best thing to do is to just discriminate 2 or 3 of the most common tabs that you are finding in that particular area.
