RECOMENDED COILS FOR THE DELTA 4000

Hello,

I was wondering what would be a good alternative coil would be for the Delta 4000?
I am just starting out in metal detecting and I am intrested in finding old coins and old rellics.
As I live here in Kentucky and I am only about 15-20 miles from the Perryville battel site. So I know that
there are some civil war releics just waiting to be found. I live way out in the country and I am surrounded by farms and old
wooded areas. I am really looking forward to getting out and doing some hunting. Right now I only have the coil that came
with my detctor.

What advantages do other coils have?

Thanks for any advice you have.
 
Not trying to hijack this thread, but I am just wondering the same thing. Specifically, is the 5x10 a good choice for Delta?

I think DiggerDug was thinking about using the 5x10 on his Alpha, but I am not sure if he had a chance to play around with it.
 
Why wouldn't it be ? It's a great coil for the Omega and Gamma ? The real test on this coil is what it's on and how you use it so give it a shot and see it for yourself. But keep in mind that if the Delta is your first detector then learn your Delta and add your coils as needed. If you think it's a magic wonder coil, it's not. But it's more stable than the 11" DD.

The 8 inch coil that's on it, will be your best coil and maybe a 5 inch coil for really trashy sites. Heavier coils will make the super light Delta feel noise heavy. Also, since the Delta does not have a manual or a auto ground balance, I'm not certain how other coils will work on it. I really like the feel and balance of the 8 inch coil on my Gamma. It goes deep and it's as light as a feather.

What is a DD coil?
the only DD's I have around here are the ones on my wifes chest!


does the shape of the coil do something special? As I have seen some that were oval.
 
JEFraze the Delta is an excellent metal detecor and if you put the 5 inch dd tek coil on it you will be one happy person,my brother in law hasnt taken that coil off his Delta since it was put on.It seperates targets so well and is a killer on coins....I highly recommend that coil for any Teknetics detector.Have fun.....Markmac
 
JEF, what type of hunting are you doing? Heavy trash? Going for depth? What is the soil mineralization where you hunt? Your general location will give us a clue on soil mineralization. We need to know, in order to give better answers.
 
I'm using the 11" DD coil now on my Delta, and as I mentioned in another post recently, I feel like its really falsing on iron a lot - right on teh fringe of a heavy iron signal I get a nice repeatable signal in teh 80's or 90's, dig, and there's nothing there, or it's an old cut nail/horseshoe nail. I think the stock coil that came with it (which I broke) might have been a bit more stable. Either way, it's a very sensitive machine and like to jump around a bit, so the more stable the better, IMO. I would love to try the 5" at some of teh old 1800's homesites around here that are just laden with iron.
 
I live in central Kentucky. As far as the soil mineral content I am not sure? Just farmland.

I am looking for both coins and relics because of all the Civil War battel sites around here.

I am very new to metal detecting and I am not sure what the coil that came on the detector is good at so I would like to know what coil is best for coins
and what coil is good for relics. I live 3 miles from a covered bridge that was build during the civil war and I would like to do some detecting around it.I also know that there was a lot of troup movement through here from both sides.

I would appreaciate any help that you all can offer
 
The 8" concentric coil that came with your machine is great for coins - I found an 1865 2 center within the first few outings I had with it... A coil like the 5" greek is nice in trashy areas, liek around an old homesite where there is a lot of metal in the ground besides teh coins you are looking for. Out in a less traveled spot like a field or teh woods, you want a bigger coil that can go deeper... but bearing in mind that a bigger coil is going to make your machine a lot heavier. The Delta is nice and lightweight with that 8" coil you have now, and I know it will work well for you. Do some tests at home, bury some coins in your yard and get a feel for how it sounds and what your readings are for various coins, then get out and see what you can find! Good luck and HH.
 
Another question I have is can I submerge the coil in water of a few inches? There is an old covered bridge near my house that was built
during the civil war. I would like to use it along the creek and down in the water if the coil is water proof.
 
Yes it is waterproof. Just don't raise the machine up with the coil in the air after you pull it from the water. That will allow water to run down the shaft and possibly enter the control housing.
 
The user...AndyNM....did a recent post on the 5x10 DD coil. Look it up.
JEF.....have you tried using 'heel' technique with the 11" DD.....if the iron is not too pervasive where your hunting, it might save you from buying a new coil. Although a bottlecap is used, its iron, so the technique/results pretty much is the same for most iron unless they are really large pieces of which will always fools the teknetics/other brands too.

"Decided to do a little bench testing. Used a clad dime and a flattened/slightly rusted Bud Light bottlecap. These, like Corona beer caps are notorious for ID'ing as dimes/quarters. This technique uses the heel edge (not the toe edge) to identify the pesky buggers. IMHO the toe edge of the First Texas DD coils do not go as deep as the heel edge. Target distance from coil was approx 7". Bottlecaps can be deep. Here is what I observed.
When the heel edge is even with or up to 1" past the bottlecap the numbers will drop to 70's-60's-50's and sometimes the teen's (do not always get the teen readings though). But the tip off is is that in doing multiple edge sweeps (remember you may have to go up to 1" past the bottlecap to get this effect) is that the ID number 99 will appear. Sometimes only one time. But it appears.
The dime will also have large fluctuating readings like bcaps with the edge technique, but there are two things it won't do. It doesn't go into the teen numbers and the 99 ID number never occurs. Practice this at home, see if your results are what I am getting. Remember, this is with the 5" DD coil. Too tired tonight to test the 11" DD.

Credit for this technique goes to Monte. He calls it the 'Edge Pass' technique. You can search for it here on FMall.

I put the targets on a box about 8" off the floor to replicate field sweeping techniques. Trying to do this by holding targets in hand and waving targets in front of coil doesn't work as well. Also, set sensitivity low enough so that the machine is not registering ID numbers randomly. You can hold the detector waist level in the air, and if ID numbers are being generated on the screen, you need to lower the sensitivity until it stops doing that. This will give you accurate test results.
I forgot to add. Disc @ 10 and Ground Grab reset to 28 instead of default 84 to reduce falsing from indoor EMI for testing purposes."
