Discrim vs notching F75

[EZrider]

Hey guys, im getting conflicting results here so im wondering. Should i use little to no dicrimination and notch "out" unwanted targets. Or should i use alot of disc and notch "in" wanted targets? What am i loseing one way or the other?

Something odd happened today while playing around in my test bed. I have a dime at 8in and a few weeks ago i could pick it up both ways all the way around it. Today i couldnt get a solid signal on it, factory reset, tweak every way from sunday and if it did pick it up it was only one way but not every time. Went into the house and grabed the BH 3300 with 10in coil and it hit it just fine both ways. I havent sent the 75 in for the upgrade as the small coil will be here this week and i wanted to send both out together. Sitting here just a little baffeld.

Notch windows are somewhat set very arbitrarily and affected due to mineral matrix, surface condition, depth
and ground moisture.[Ruling out detector variables.] [I'm going to specify coins] If you have a preset
notch, what works in one place may not work in another with the same values. More specific selectable notch;
those factors, in targets, can cause you to lose or accept targets right at the borderline. I've had tabs that were
notched out accepted because the depth of the tab caused the signal processed by the detector to push it up
one notch, yet when I got it out, it nulled. This is because many detectors are built to raise the i.d., or its simply
an indirect byproduct. Notching reject may cause a good target near a rejected one to never be heard. Or again,
in the case of the nickel range, targets are pushed into the reject category, due to depth elevating them to a higher
notched out targets, tabs. ANY targets aspect is changed when using a notch or a lot of discrimination. REGARDLESS
of what the maker says.
You already know that putting the word LOW in front of a target means; its less easily detected, regardless of frequency.
Its not straight line methodology when involving detectors. I've simply found too much thin gold jewelry at the beach
with a 1280 Aquanaut at 2.45VF, the lowest frequency on the market. Yet we are told constantly we need high frequencies,
for these same items. Should I disbelieve my lying eyes?
When you add discrimination, this just accentuates the problem on getting the best possible signal.
(Is there ANY possibility you might have missed something in your reevaluation of your F-75-the least little
thing can cause a huge difference?)
Personally I never use notches for the above reasons, and I have the meter & tones to help out-without them, I would have retired.
Yet I still dig a huge amount of questionable targets. If that sounds like a contradiction it is.
Life is full of them.
