My really trashy park program...opinions wanted

[sekypaleo]

Sunday I will be hunting a park that was the site of a female college in the 1850's. There is one small area that is super thick with modern trash....not iron, but stuff like foil,can slaw, bottlecaps, screwcaps...you get the idea...I mean THICK. I know there are good old coins there, as many years ago in one little spot in this area that was "fairly clean" I got a seated dime. Here is the program I came up with to hunt this place...thoughts?
Freq...4khz
Reactivity...3 (maybe 4 or 5 even)
TX...2
Sensitivity...85
Silencer...2 (maybe 3 if bottlecaps are an issue)
4 tones
disc at 5
tone 1 at 100khz
tone 2 at 100 khz 2/3 break at 40
tone 3 at around 500 some with 3/4 break at 75
tone 4 at 800khz
notch 1: 5-40
notch 2: 97-99
iron volume at 0
audio response at 3 ( to hear soft deep targets

the purpose of this program is to cherry pick IH's, and silver...thoughts?

If really trashy and most coins dug are not below 5 inches I would go reactivity 4 to start and adjust down as 5 is way to much usually. Easier to test in the field than guess on the boards. If you can tell bottle caps from sound or xy. Then silencer 1. I would not notch so much, listen to the tones and get better depth Learn the sounds and discrim less. I like iron volume at 1. You will get better feedback from the ground than ya will from trying our best guesses. It will lead you to the right area but to make it best for that area is up to you Solve the puzzle. You will get a wide variety of program changes but we all have different ground and circumstances.

4 Khz is a good choice but remember you may miss deeper nickels and gold items (gold coins?). Unfortunately in order to find IHCs and some silver you will have to dig a lot of crap that will undoubtedly try to hide the goodies.

Silencer at 2 will miss deep targets of all types, try 0 or 1. Using a -1 Silencer in aluminum-y areas drives me bonkers, but separation is better which you will need running 4 khz. 4Khz only runs in TX = 3.

Tones and tone breaks look good - above 75 in 4 kHz usually indicates large copper or silver coins. Some silver dimes (really thin ones) can ID around 72-73.

It's probably best to dig those steel bottlecaps to see what's been masked, but 4 khz is the clear winner for this. Put audio response to 5 to hear those whisper targets. The surface targets won't be THAT much louder

The most important thing to remember is "Dig by audio". Some pulltabs will ID in 4 kHz around 50-51, but a COIN that IDs at 50-51 WILL SOUND MUCH BETTER and can be detected a lot deeper. Aluminum screwcaps are the devil, however; and are best identified by "pinpoint length"

If you get there and 4 Khz is too chatty, try 8 Khz and notch 5-45, and 96-99. Smaller aluminum will come alive, along with some bottlecaps - this all depends on if you have any EMI present.

Good luck!

mY huge silver came in at 98

I usually get a ton of noise when I use a low frequency and high reactivity.

I agree with having the tones set pre hunt. But the rest of it needs to be done at the site. Use only what you need to on the other settings. I also think a little iron volume is needed so you know how many iron targets you are hitting. How else will you know how much reactivity?

I start almost every hunt in Basic 1. From there I adjust everything depending on the site and what I am hunting. Sometimes it is relics and coinsat old houses. Sometimes it is just coins like old fair grounds. Sometimes I high tone nickels. I can make every adjustment including tones in about five minutes or less.

The Deus is a very versatile machine. But it is not that complicated. Tune it to the site and get the most out of it.

Why 4khz?
What type of trash and how much mineralization?
I would think frequency is the primary site dependant variable................

4kHz is going to make it easier to discriminate out a bad target. Try running your machine over a screw cap in different frequencies. 4kHz expands the the TID line. As you start going up in frequency, the targets get bunched together at the high end and start sound ing really good.

That's what I thought--convenience for BC elimination
I would much prefer to expand the TID range on the other end where the gold lies.
I have noticed bottle caps show up nicely on the left side of the HS in air testing but that doesn't follow through once in the ground,,,what a shame/advantage that would be.
I wonder if that's an item in the "wish list"
