F75 able to notch out more than one notch?

[Massbaycolonist]

Hi. I have read the manual regarding setting notches on the F75. I would like to hunt only the middle range for jewelry. I know that iron and other very low VDI's can be discriminated out by using discrimination. But can all the higher coin ranges be notched out if I'm not interested in finding any coins? Thank you.

Yes you can notch out anything you want. With the 75 you can notch out the high or low side also. Heavy notching can induce masking/silent masking though.

Thank you, EZrider. Sounds great! Yes, I understand about the masking- 'Mid-range' targets can register quite high sometimes. If you notch out the high side, you would not get a signal on these masked out targets. Right? I think very deep targets will register higher. For example, A very deep nickel, normally a mid-range target, would probably become a high range target. (I think). Good point, though. So you would not want to have a real tight midrange, leave some room at the upper levels of the midrange. Thanks again, happy hunting.

Actually I don't believe you can discriminate or notch out anything over "65" on the VDI scale (0 to 99) so you might be stuck digging those pesky silver dimes, quarters, halves and dollars. You'll have to rely on the VDI to tell you when to skip those signals.

You will dig the pesky clad ones too

Sounds like fun! btw, what are those intermittent red "ignore user" buttons that sometimes show up above or usually over, some members user names? HH

That's a deal killer for me, Charlie. I'm getting too old to be digging up all those silver coins. Actually around here, anyways, they are almost all copper and clads nowadays. Too bad we can't notch/discriminate out the coins, because otherwise, the F75 sounds like a real nice machine. I think the CZ-21 is more appropriate for me, as Sandman says that with the CZ-21, you can hunt in just the middle range. HH

Keep in mind if you notch out numbers you will also get bleed over to other numbers in close proxcimity to the numbers/area you notch out.

I hunt with no discrim. I want to hear everything.
Good luck.

If you have the discrimination at pulltab and you set notch to pulltab then you notched in pulltab. Also Notch puts machine in high gain makes it very sensitive to interference Turn the he Sensitivity down. Any discrimination above 15 puts it in high gain turn the sensitivity down. I hunt at discrimination at 10 no notch. Make sure when you play with notch you re-notch out iron full slash or guess what you notched in iron and it will be erratic. Do a reset if you dont understand watch the noise go away or follow my post here. http://forum.treasurenet.com/index.php/topic,182656.0.html

Another thing I found out the other day, I had the discrim all the way up because it was a very trashy site. I found several nickels even though they should not be detected. I would get a signal then break the ground and the signal went away but a pinpoint brough out a nickel. So it must be the halo effect allowing its detection.

Why not get an F70? AFAIK, you can notch out the high conductors with it. The F70 really only lacks a few things that the F75.. nothing really important (backlight, DD coil, static AM mode that few use). It's also a lot cheaper. ..Willy.

Hey there Jim. Yup, got 'er. Now I.m stuck playing around in the garage doing pointless little tests. Did find out, however, that the F75 w. the stock coil shows a definite increase in sensitivity to small gold vs the MXT with either of the stock elliptical DD's. It's not a GMT, especially with the signal boost turned on, but it's bitin' at the heels. I also don't really see any problem with interference. In the garage, sensitivity cranked up near max (90 sumthin'.. can't quite remember) and with overhead fluorescent lights going full tilt, it seems just fine. Maybe I'm just too used to running my detectors that way and have learned to mentally discriminate out spurious signals. ..Willy.
