"Signal Chop" from too much discrimination

[earthmansurfer]

This is for those new to the E-Trac (me included). In my soil I often see coins that in the stock coin program, drop down to where Fe discrimination starts. This often "chops" their signal. I experienced this today as in the video (only one minute long). Afterwards I opened up the discrimination pattern another 3 or 4 Fe levels down (to 19 or so). This still allowed for a relatively quiet hunt - in my soil. I ended up also opening that top portion of the stock coin program, so that the top Fe line was closed, except for 40 to 48 (read that is a good set up some where here I believe) - all else was open, as in the pattern program mentioned below. Note - Deep was off, Fast was on, Trash Density high)

I hunted the first 2 hours of my 3 hour hunt with discrim open down to 27, but this was pretty fatiguing, audio wise. (The Beat Goes On - Minimal Discrim Pattern, available on his website. It is nice if you soil allows and/or you can handle the audio.)

I am working on reaching a compromise.

Hope that was helpful,
Albert

ps - Just trying to get up some videos before Winter sets in. Hope this isn't too much. But, I prefer to put them here (and without ads) as it seems more accessible.

i hunted all day today with fast off based on your other video. i did like it. a little bit smoother all the way around. i have my screen open to the fe27 line straight across and yes, it can be brutal.

your videos are very useful and i enjoy them. thanks for making them and posting them. im sure i speak for many others as well.

Another good video, Albert, I always enjoy them, they make me think.

This is the reason I do not like tight disc patterns, i have seen some real tight disc patterns posted here and they just do not work for me, I prefer a much more open pattern. I think it allows coins more freedom to jump around a bit, especially nickels! If your disc is more open it allows signals to sound a lot more smooth instead of choppy

Thanks for the information.

great vid!

Great post! Using FAST on will degrade signal as well.

Big Boy Bart (that sounds good),

Yeah, fast degrade the signal. But you know what is interesting regarding that? Fast On is with fewer filters than fast off. That is why I often use it. I have to experiment with getting to know that sound, for I think the fewer filters (often) the better as we get to know the sounds better. But I know it's dangerous with Fast On as the signal is MUCH easier to miss. Thanks for reminding me, got to practice.

ps - Thanks guys for the comments. The videos are a blast to make to boot. I wasn't a star athlete in school, so no high school memories to watch on video. These will be my Winter contemplation! hehe

The one thing i found out fast about getting the first ET on the east coast. The patterns that come on the machine are considered world patterns. Thats why some copanys have euro machines and US based ones. On top of that. One pattern may work in one part of the country while not in another. The stock patterns may work to get someones feet wet out of the box. But not perfect.

Well said EZrider (good movie and Jimmy Hendrix song btw!)

I dug a deeper target today and the curor location was a bit above the discrimination line. (I moved it down since this video.). The target was at 14 and my discrimination line was at 18 or so. And yet it "chopped"??? I opened up the screen and the chopping stopped. I think I will slowly inch that line down, as much as I can without getting too much iron feedback. Need to find a happy medium as the low discrim setting of Fe 28 is just too much for too long with all the iron in my ground.

Has anyone else noticed this "chopping" of the signal with targets noticeably above the discrimination line (like as in my example above)?

Thanks,
Albert

Albert, When a target pops up like that, hit quick mask to get a better look.

earthman... what program do you normally run.. Stock coin or what... just curious. I have been experimenting with a program that is alot more open for coins and thinking its better.. I kind of borrowed different programs and put what I consider good points from each into one.. but one program is not necessarily good for every one... I will post a pic of my screen if you want...

 

[earthmansurfer]

EZrider - Totally, yes. I always hit Quick Mask and did so in the video to clear up the "chop". But thanks for mentioning it as that is Great Advice!

Gone Hunting - I started out just running the stock coin program for a week or two. And I was also playing with a mostly open screen after that first week or two, most of the top line was closed and the Fe discrimination started at 28. But that was hard. In open areas I would just run an open screen, but there aren't any open areas around here!
Next, I edited the stock program. I opened up the Fe another 3 or 4 points (due to the chop). And I will continue to do a little here and there to find what works well in my soil. You said that part really well - I agree. I guess I'll create a few different patterns for different sites and different settings and just switch between them. I don't need many at all. The sites I hunt are all trashy with iron for the most part. I think it's also good what you said about borrowing patterns from different users. I did that with the top line, Fe 1. I closed it off and only left open from 40 to 48 (don't quote me on that.) I'm still playing with things. I don't like running discrimination much but the sites are too trashy with iron, I have to run some. I definitely do better due to the reduced audio fatigue as well as fewer targets to sort through.

Sure, post a screen shot. But you got to say why you did some of what you did! Then I can learn.

Thx,
Albert

Kind of hard to explain but the high ridge on the left side is of course for nickels and the silver War nickels too. the peak is 04-12 and 04-13 I have had a lot of nickels jump.. Not that much but it helps cut out the chop.. now this is the one I personally use on old home places usually there is not any aluminum pull tabs...
the second ridge starts at 08-32 and slowly works up.. I have that for weird sounding IH's.
On the very left side there is an indention for 3 cent(nickel) varieties... I scanned on I have and it hits all around that area.. bad thing is tin foil will hit there too.. You have to make sure the site your at predates foil or this will drive you nuts..
the rest of the pattern is to descrim about as much of the iron as I can with out the chance of nulling out a good target... the secret with this program is repeatable signals will help you decide..

On the quick mask is 07 and 27 with the some cut out... its out of Mr. Andy's book...
