BOTCH NOTCH F75

[rsadler]

Story (unrelated to my questions): I am the new kid on the block regarding my F75. My first detector (I believe) was called a "frontier." My dad took me to the battle grounds at The Wilderness Battlefields near Fredericksburg. Someone came up to us while I was detecting and said "I don't think you are suppose to detect in this park." My dad and I did not have a clue! We could have been in DEEP trouble; never considered it was illegal. I made some wonderful finds that day at age 15 (1965). Years later I let my daughter take the civil war relics to her 5th grade class and that was the last time I ever saw my treasures. Has anybody ever owned a Frontier?

Question: I believe my notch is botched up on the F75. I set the notch through 65, and then "unnotched" the nickel. When I swing the detector it still will hit (sight & sound) on all the notched settings (iron, tab, etc.). I see where all but nickel has a strike, but I don't understand the reason for trash still showing up. I have the sensitivity on 60, disc about 15 and Quick GB. I don't believe there is interference where I am scanning. Any ideas or suggestions? P.S. I cannot tell you how grateful I am for all the info on this site.

Sounds like you want to hunt for the highly conductive stuff above #65 and for nickels. Let's keep it simple;

Do a factory reset as per the F-75 manual. After factory reset the Disc. will be on # 10. (maybe #15 if you have an updated unit)

Push the MENU button until you are in the Disc. menu and then turn the settings knob until the Disc. is set on #65. (that's as high as it will go)

Now push the MENU button to get out of the Disc. menu. Notice that the first 5 categories of the seven at the top of the display (IRON, FOIL, NICKEL, TAB and ZINC) have full slashes through the words. This is telling you that all numbers up to # 65 are NOT being detected and all numbers #66 and above ARE being detected. Dime and Qtr are NOT affected by Disc. or Notch.

When you Notch IN (detected) or OUT (not detected), you will be Notching ranges of numbers (i.e.NICKEL low #26 - 30 and NICKEL high #31 - 35) and not individual numbers. (We'll save that for another time). So, if you want to Notch the two NICKEL ranges back IN (detected) you'll need to push the MENU button until you are in the Notch menu.

Notice that the number #1 appears in the window of the Notch menu.. Although I didn't see it anywhere in the manual, that number means nothing. No Notch is set, yet. The #1 is a convenient place for the menu to come to rest after a factory reset. As a matter of fact, none of the numbers in the Notch menu ever indicate if or where a Notch is set. The numbers are only there to help you set a Notch in a certain place but other than that they don't mean anything.

Now, while in the Notch menu, turn the settings knob until ANY number #26 - #30 appears in the window. Now push the MENU button once to set the Notch for the NICKEL low range (#26 - #30). Notice that you can put any of the five numbers in the window (#26 - #30) and the whole range will be Notched back IN (detected) Now while still in Notch menu, turn the settings knob until ANY number #31 - #35 is in the window. Press MENU button once again to set Notch for NICKEL high range (#31 - #35). Now press MENU button one more time to get out of the Notch menu.

Notice that IRON, FOIL, TAB and ZINC have full slashes through them indicating that they are NOT being detected. NICKEL, DIME and QTR have no slashes and ARE detected.

Thanks Ron for taking ALL that time to explain. I was merely experimenting with the notch system. Using 3H should I still be hearing low sounds? Should I still see the numbers below 65 flash up on the screen (say I notched everything below 65)?

Notching OUT (not detected) everything up to #65 and Notching NICKELS back IN (detected) (unNotched) you should only be detecting #26 thru #35 and all above #65. The fly in the ointment is that you had your Disc set to #15. It doesn't matter which one you did first but by Notching OUT (not detected) from #1 thru #15 and then turning the Disc to #15 you just unNotched (detected) #1 thru #15.

On the other hand, I believe you said that all words other than Nickel had a slash through them. Did you get out of the Notch menu before you checked for slashes? You need to.

The way you have it set up (#1 thru #15) detected, yes you should hear low sounds while in 3H.

Try what I suggested and see what happens.
