Question about discrimination................

[TreasureHuntersSupply]

I have been using the CTX for a couple of days. I am very new at using it. I am an Explorer SE user. I have never used the Etrac, so some of the terminology is new to me. What is meant by discriminating out something, and also discriminating in. I read in a recent post, Thanks for the tidbit about discriminating out the first two CO line to increase stability on the E-Trac. Of course this was this was in a certain situation in which he was doing that. I do not understand completely what is meant or going on when do that.

Do you have in possession one of Andy Sabischs' books on the Explorer and E-Trac? A lot of your questions and concerns are covered in that book. By eliminating, discriminating or rejecting, the 1st or 1st and 2nd CO line on the E-Trac on some beaches eliminates false chatter for smoother operation.
Looking at discrimination as in or out could get confusing , a better way is accepted or rejected targets.

Discriminating something OUT is rejecting the ferrous and/or non-ferrous (conductive) properties. The opposite would be accepting those ferrous and/or non-ferrous (conductive) properties. For example, if you discriminated out ferrous line 35, you would be rejecting any targets with a ferrous value of 35. If you rejected CO line 01, you would be rejecting any target with a non-ferrous (conductive) value of 01. etc, etc, etc. HH Randy

When you discriminate something "out" you add a targets FeCo number to the discrimination patterns so as to not detect it. You will hear a break in the threshold called a null when you pass over a discriminated out target. I believe with the CTX there is now a reject cursor so you will see the cursor on the screen to give you an idea of where the target is. The opposite is true for discriminating something "in" you remove it from the pattern so as to be able to detect it. If you're familiar with the Explorer SE its not that much different other than you have about double the amount of FeCo numbers in your pattern.

Let me get this straight, the white area on the screen is accepted, and the blue area on the screen is rejected or discriminated out. And yes I do have Andy's book, and will look at it for more information thanks for your help guys.
