Notching the F75

[shooter]

I know there are 2 notch ranges for each item, I'm asking if you see 2 physical slashes over each item fully discriminated. I'm only seeing 1 and still hearing and digging tabs.

Got it now, thought the slashes were showing side by side, went by the book and looked real close and could see the UPPER slash and then the LOWER with a tiny break in between to show the whole range being out.

How to use Notch on the Fisher F75 and LTD's

It really is simple..the manual appears to make it difficult..and that's only because they forgot to stress the Fixed set of numbers for notching abilities.

In other words if your detecting in a park.. your using Discrimination at 25. all of a sudden your getting a lot of one type of pull tabs. Say it falls in the
#38 Target ID.. Over and over again..You go to notch..press menu dial to the number 38..and press menu. A dash will darken up above on the left side of the tab name on display. You removed the Number 38...but you also removed 36, 37,39,40,41,42,43,44,45.....Because the notch is set up in a fixed set of numbers on each target category..36 through 45 is the lower half of factory set notch numbers in tabs area... You will always remove all factory set numbers when notching out target numbers that is above your discrimination setting...You will always be putting the numbers in with notch if they are lower than your discrimination setting. You need to know these notch fixed numbers to understand the notch system.

Now if your running Discrimination at 40..then the notch system is designed to do just the opposite of Discrimination..So 36 37 38 39 40 will be notched in..
41 42 43 44 45 will be notched out. Notch always does the opposite of the Discrimination. So if you want all the fixed numbers in tabs on lower half out..Move your discrimination to 36 (Get your discrimination number at the lowest fixed number) in the range you want to remove. Before, you set the notch.. It's your choice..but you have to work the two systems together for full benefits.
