What are best settings for hunting trashy park with Gamma 6000 ?

[ToddB64]

Hi everyone !

My favorite park has lots of pennies, dimes, nickels and quarters, but most of them are so surrounded by close trash that my Gamma has a hard time making a choice and keeps jumping from one target icon to another, back and forth. I don't believe this is an EMI problem; just too much trash ! Targets that I decide to dig, weather coin or trash, are normally 1/2 to 7" deep.

I use the Pinpoint button and listen to the VCO audio to locate the center of the coil over the target, stop movement, and press a golf tee into the ground at the spot where the audio was loudest / highest pitch.

Below are my usual settings after finding a rare patch of "clean" ground and performing GROUND GRAB, which usually indicates a ground value somewhere between 50 and 65 (Red, yellow, and brown iron-bearing clay minerals.).

Volume: 10
# of tones 3
Sensitivity 60
Mode: Discriminate
Disc. level: 42-43

Would changing any of the settings help to reduce the problem of the target indicator "jumping from one target icon to another, back and forth." syndrome ?

With regard to my (3) questions, one above and two below, what has your experience been in these areas ?

I'm using the 42-43 Disc. level so I don't miss any small gold rings, etc.. Do you think raising this setting would help to reduce the target indicator from jumping around, without missing any small gold rings, etc. ?

Also, I'm using Sensitivity setting 60 to get reasonable depth on coin-size targets at up to 7". Do you think I could reduce this setting without sacrificing much depth ?

Thanks for any advice you can give !

Hello Todd, This may help a little, I hit the park with my Delta 11DD last Sat. I could not move without my det. going crazy. Not having adjustable disc {fine tuning] as your Gamma, I don't notch out anything and just use start up setting of 40. Knocks out most iron [not bottlecaps] I've noticed on shallow coins down to a couple inches or a little deeper I would have a terrible time pinpointing regardless of how low my sense setting. Concentric coil also like this on shallow, some old threads someone talking about lifting coil until targets almost gone to pinpoint is the only thing that works for me anyhow in sites like this. All the chatter I know tough to ignore, but det. doing a good job reporting targets accurately, I'm "green" but I guess only option is to start notching [go cherry pickin] I'm hoping 5DD helps with this [Ive not tried mine yet] Hope some of the other guys that have hunted with notched out items to control chatter get on here and help you. I judge my coin hits in trash by how jumpy they are . I ignore the coins that jump more than about 4numbers from their normal signal, I know I'm missing some good stuff but I don't dig much trash, and coin hits that keep stable numbers usually coins [ for me anyway] hope you get ta pull out a big ol gold ring for hunting sites like this!

Mike.......Thanks for your input !

Although you are speaking from experience with the Delta 4000 and the 11DD coil, whereas I use a Gamma 6000 and the standard 8" open coil, I believe some of your tips will be useful to me.

I think when you get around to trying out the 5DD coil, you will hear less chatter and see less icon jumping in the trashy areas...just a guess based on using a smaller coil.

Anything you can do to reduce the total amount of signal feedback that the control box circuitry has to analyse in those trashy areas should help the circuitry to focus more on a good target.

Of course, what a dug target actually turns out to be all depends on the conductivity level of certain trash items being able to fool the icon selection process !

Good Luck !

I know it was of little use to ya, but watching your post not getting a response bites! You certainly were nice enough to take time for me and I want you to know I really did appreciate it. Good Luck ta you also, Todd

In thick trash, a 5 inch DD coil is a must have. The Gamma is a super nice detector. I prefer its stock coil over the Omega's stock coil. It runs quieter, deeper and is easier to pinpoint with. The volume control on the Gamma is also a nice bonus.

Mike, I appreciate your kind remarks. Taking time to help other detectorists is a pleasure !

I was wondering why some of the experts like Monte hadn't jumped on my post, since he usually enjoys giving advice on technical questions.......maybe he will eventually.

Let us know how the 5DD coil works on your Delta.

Swing Slow & Low !

I agree, the Gamma has some nice features which makes me wonder why it hasn't received more attention in the forums. Seems like most posts are about the Delta, Omega and T[size=large]

Hello Todd,

I also have the gamma, this is my 2nd season with it, well it will be my first full season, I also use the standard 8", and it took me about 2 mo. last season to figure out the machine around high trash areas, but now i can tell wether a coin is over or under or next to a rusty nail or similar pretty easily, my partner has a the new whites v3i (which is a very nice machine) however i find at least 3 times more than he does, and I usually end up double checking his holes for him, Maybe he don't yet know how to use all the bells and whistles yet tho, but if your new to the gamma - just be patient, my normal settings are basic turn on and ground balance, with sensitivity as high as possible, and even next to the trash cans i can pull coins out right next to the pull tabs, my buddy neadless to say watchs and just shakes his head, of course i just grin.


last year i was on this site and learned alot, of course i lost my info and had to rejoin, and agree not enough topics about the gamma's, they are a very good machine, once you learn all it can tell you. a few days ago we pulled our first gold for the season outta the ground, in a corn field none the less, one thing for sure is the gamma loves silver and pennies, i know none of this is a 'good advice' answer for your question, and i wish i could help more, sorry.

How long have you had your gamma

I was out-of-town for a couple of weeks on a relic hunt and doing a seminar. Just catching up on forum stuff.

My favorite park has lots of pennies, dimes, nickels and quarters, but most of them are so surrounded by close trash that my Gamma has a hard time making a choice and keeps jumping from one target icon to another, back and forth. I don't believe this is an EMI problem; just too much trash !

Every detector made is going to have to deal with multiple hits in a heavily-littered site. You and your Gamma are no different. It's seldom and EMI problem, and there are just a few ways to deal with it:

Targets that I decide to dig, weather coin or trash, are normally 1/2 to 7" deep.

Most coin-type targets are going to be in the surface to 4" depth range, and some deeper coins from 5" to 7" or 8", so there's nothing uncommon here.

I use the Pinpoint button and listen to the VCO audio to locate the center of the coil over the target, stop movement, and press a golf tee into the ground at the spot where the audio was loudest / highest pitch.

I always use the Pinpoint function, I enjoy the assistance from a good VCO audio, but I don't mess with gold tees much. I simply pinpoint then gab my rounded-off screwdriver as I kneel down and recover the target. No extra steps involved.

Below are my usual settings after finding a rare patch of "clean" ground and performing GROUND GRAB, which usually indicates a ground value somewhere between 50 and 65 (Red, yellow, and brown iron-bearing clay minerals.).

Volume: 10
# of tones 3
Sensitivity 60
Mode: Discriminate
Disc. level: 42-43

The Volume control is one function I wish they would not have put on the Gamma or Delta. You have to run MAXIMUM or you're going to lose responsiveness to higher-conductive targets, such as halves and dollars. They should have just peaked that setting in engineering the unit and left it off the adjustment list.

As for Tone ID, I like to use only two of the four options: For casual coin hunting I prefer the 4-Tone audio as it gives a nice mid-high audio for the US 5
