Given that a lot of older coins in the US seem to come from the 6 - 8" range

and you are specifically looking for the older stuff.

What detector and coil choice do you start off with when hunting a new to you site that has a strong probability of having been hit hard by other detectorists?

Without starting any debates about which detector is best for old coin hunting please feel free to add any comments/specfics about why use that particular detector/coil combo.

In other words and simply put, what is your confidence setup for this scenerio?

TIA

The Exterra's seem to be good coin hunters. Are you planning on another coil? if so, which one?

TIA

HI Tom

It depends on the area.........if it is a large piece of land, I like a 4 pole filter White's 6000 Pro XL with an 8 inch coil or 5900 Di Pro SL with the same coil to do some hot spot scouting. I usually take a 2 pole filter machine along like a Tesoro or IDX Pro to clean out the hot spots with. If I was limited to one detector it would have to be my Ol trusty Toltec ll with the stock 8 inch coil as it does everything well for my kind of hunting, from relics in the iron to coins in the nails. This is the opinion of this Ol coot! I'm sure others will diagree, but that is the point of this post.......ain't it?

and the 8"coil lets you work those hot spots too. Good post Thanks!

I bet you have quite a few hours on that trusty Toltec. Refresh my memory, what Freq does it operate at?

Thanks.

I have at least 2000 hours on that machine (Toltec ll) since I bought it new in 1994. It operates at 12 KHz and is is sensitive to both small gold and silver and with the ED 120 discrimination it operates quietly in the iron trash even with the 8 inch coil. Using one in the nasty iron nail infested places it takes some different coil manipulation to get the best out of it. I may raise my coil slightly in the iron while doing a slow sweep when I get some good beeps among the sputtering of the nails. In one sweep of the coil I may get 4 or five sputters with a 'good beep' thrown in between them. Using the meter and making short wiggle passes over the good beep I can isolate the good targets.

I am sold on my F 75 for those hard hit and trashy sites. I have one site in particular that has been hard hit by others and myself. Myself with two Tesoro's and two cz's. Upon getting my F 75 in April of 07, I hunted this site with the stock DD coil and promptly began finding old silver and many, many wheaties, in addition to the occasional gold and silver jewelry item and other items of interest. When the 61/2" elliptical coil came out I got it and began re-hunting the site and continued to dig the occasional silver coin and jewelry item that had been masked, or partially, so. The elliptical coil has good depth, 7-8" on dime size targets, and on sites of this nature I use it at least 50+ percent of the time. On such sites, I will start out with the stock coil and then re-hunt again with the smaller coil. I have found when using the small coil my searching is much more methodical. I am covering much less ground with the small coil, so I find I investigate marginal sounding targets much more carefully with it. I also hunt these kind of sites from numerous directions and angles. This particular site has yielded me and my F 75 almost 350 silver coins and several gold and silver items. Back in the 80's and 90's, when it became available to hunt, I've been told silver was leaving the site by the pocketfull and by the late 90's, was hunted out. As we all know, this is never the case.:biggrin: HH jim tn
 
If you stop and think about it, the first time through is cherry picking. If good targets are coming out, then after the cherry picking comes the unmasking hunts, followed by the dig all non-ferrous down to what ever depth your current machine will reach. If it has really been hit hard there will not be many targets present. I'd be looking to see if there were any non-ferrous targets present in the 5" to 6" range. If there are then 1) either full of fill dirt or 2) not hit as hard as you thought. Sometimes a site worked over site might have a layer of surface trash on it that can be anywhere from the top down to around 3" deep that has accumulated after it was gave up on. I have also come across several sites that were excavated that had a layer of surface targets and nothing underneath.

I like the stock 10" elliptical concentric coil on the F5 in the two tone audio mode (ferrous -non-ferrous VCO). The VCO non-ferrous tone will easily tell me what depth the non-ferrous targets and allows me to focus on the deeper targets without having to watch a meter. I can do the same with the Omega and the 11" DD coil.. An hour doing that will pretty much tell me whats going on. The biggest reason I got the Alpha2000 is to put the little hockey puck DD coil on and take it to the high trash areas and just watch the depth display and listen for non-ferrous targets. Anything in the 5" plus range gets recovered. I've got some good ring sites where I think this setup will allow a little more focus over the VCO mode due to the amount of trash.
Good luck.

Tom,for the worked out parks here in Southeastern Michigan I have had a lot of success with both the Sovereign and Explorer.These Minelabs are deep and gives me the confidence I'll find those deep coins missed by others as I navigate through the trash.I think the 10 inch coil is the best approach for the first hunt in these worked out parks.I just found one of these old parks last Saturday near Goodrich.This old twenty acre site didn't even produce clad for the first couple hours.I used a Sovereign and the other hunter a V3 my oldest coin a 1927 wheat and the other hunter a couple of 40-50s wheat's.(I felt we got skunked)Anyway this park has been hit hard and I'm confident that either the Sovereign or Explorer will find those deep silver coins.We ran out of day light and in this county a permit is needed for metal detecting or a possible fine.My first chance I'll head back to this park with more time and a permit.

I would like the 3KHZ coil. Have heard very good things about it, Beale.
 
I hunt the site first with my XLT...........Coin& jewelery Mode.
I remove as many coins, pull tabs, and other junk items as possible.

After this is done I use my Minelab SePro

Iron Mask 22
Sensitivity 26 Floating
Fast on
Deep off

I dig all targets in the middle to upper right hand range on smartfind screen.
I only dig targets that are half way down the depth scale..(6" about) or more. .

I usually find lots of Wheat cents, and Silver if it is there.. Coins are on angles, or next to nulled targets.. It's amazing what the SePro can find at a site you just cleaned out most of the trash..............
 
If you would have asked this a few months ago I would have said my Whites XL Pro with the 9 1/2 inch coil but I have been having a torrid love affair with the Minelab Sovereign Elite lately. I would start with the 10 inch coil and then hit the high trash areas with the S-8.
 
Hi Mike,

Yesterday I stopped at a one room country school house that has been hunted for years by everyone and his brother. It had sat unused for years and let to run down but, some recent renovation preservation work has been done on the building. There is no modern trash present.. I started out using the Omega and DD coil in 2 tone 0 disc, after 30 minutes and no non ferrous targets I switched to single tone disc 16. I immediately then started picking up targets and not all of these had nearby masking iron.

Hi Ron,

Sounds like that park has been hit very hard. Would you see any benefit to using a bigger than 10" coil there, say the new pro coil? Or is there a lot of non-ferrous trash?

We don't have the large old parks up here where I am located but a few years ago I hunted a small park that gave up quite a few Barbers and IH's using the CZ-5 and 10.5" coil. Most coins found were 8" or less and gave only one way hits using the big coil. Amazingly, since this park was located in a small City, there was almost no modern trash but lots of mid depth iron where the coins were located as well..

HH Tom
 
In two tone were those targets grunting iron and you were ignoring them? What's the ID break over point from low to high tone in two tone mode? Or is this the (in)famous change in sensitivity as the Disc level is changed?

Hi Bill,

I'll be glad to answer you over on the Tek forum. I would like to keep this thread on topic. :)

Tom,after the first search in this park and unable to produce my next hunt would be with a larger coil.With the wide open spaces and loam type soil in this park the WOT 15 inch coil would be my number one choice of coils.Another tactic would be use the same coil and look for a sweet spot in the large park that still produces and on a later hunt switch to a larger coil.
