I got my 705 on June 4th. Only been able to get out a couple of times, so I am still learning this machine. I am by no means new to detecting, but new to ML and an ID machine. This morninig I took the 705 to an open field that once held several houses. It is in an area that has been getting bought up by the state for a new freeway. This has been happening now for 4-5 years and the area has been just pounded to death.
There is so much trash in these spots that it is almost impossible to find a clean spot for ground balancing, signals every 4 or 5 inches.
When you get your detector ste up correctly, do not get discouraged in these areas. Go slow and listen for the good repeatable signals in the trash.
I didnt find silver...today, but I will take wheats and indian heads over zincs any day. I know there are more barbers here. The IH is very crisp with full Liberty in the head band.
Good luck and happy hunting.
 
Nice find Bill! :thumbup:
I love finding Indians, because they are a good indicator of the possibility there are more great finds nearby.

Keep at it. I'm sure that you'll find more there.
 
Congradulations on the nice finds.. I would say it is time well spent searching that area.
I am searching a site kind of like this now.. only had on house, but it was huge and it burnt down in the early 1900's.
Iron everywhere, but I have found some wheat pennies and 3 silver dimes so far.
earliest was a 1923 Merc.
I agree... there probably are some nice coins in there waiting for you.
Good luck and keep up the great finds!!!
 
Thanks guys, I know 3 wheats and an IH isn't a great haul but, my post was to show that with a little patience good finds can be found in some of the worst places.
I have been to this same site with another detector and felt lucky to find 1 wheat.
I should have shown the amount of trash I removed but hopefully everyone knows by now that it comes with the hobby.
 
A nice addition to your arsenal would be the little 6" coil. I got one recently. What convinced me was this. We were hunting a site similar to the one you described above and Gerry digs a 1914 D (VALUABLE) right out from under my nose in a spot we had been over 5 or 6 times with our larger coils. Picked the small coil up the next day and that evening found 3 more targets in my own back yard and let me tell you I have been over that yard a lot. That little coil will get in between the trash targets. Also IMO on tends to slow down a lot trying not to miss any spots.
Slowing down always helps.
 
Great points Bill! Digger mentions in his ebook, that he doesn't believe he has found most of his older coins due to having max depth, but due to the seperation provided by the smaller coils at the trashy sites. I have the 6" MF (7.5khz) coil and it does work great at picking coins out in the trash. Depth is great too for a 6" coil. Found some clad dimes & copper pennies at between 7-8". I definitely would like to try the 6" 3khz 'Digger' coil though!
 
The thing is, I am not sure if the frequency really makes that much difference. Is 4.5khz going to keep you from finding that silver coin? I would love to have the 'digger' but can't justify the extra cost. Not now anyway.
So far, this 9" coil has been able to pick coins out of the trash. It would be interesting to see if I can pull more out with a smaller coil.

You can certainly find more in trashy sites with a smaller coil, and even better with a DD.
I'm starting to get an itch for a small 7.5kHz DD. If there are enough others interested, I'll contact :coiltec: and try to get an idea of what our chances might be.

As far as frequency goes, it's more a matter of how various metals respond to different frequencies.

Here's a quote that pertains...

"According to George Payne, the father of today's metal detector technology, a silver dime responds best to a frequency of 2.7 kHz. Nickels and gold jewelry respond best around 16.5 kHz. All other US coins are most responsive to frequencies under 10 kHz. Gold nuggets are better served with a frequency of 20 kHz or faster."

So you see, it really depends on what you're looking for, as well as to what extent you want to tailor your rig to go after something speciffic. Then throw the variable of soil conditions into the equation too, and you can see why the Xterra's choice-of-frequency capability makes it so versitile & remarkable.
 
Oh, I do understand every point you made, and the differences in frequencies is why I bought this ML. At this point my main focus is old coins and jewelry. This 7.5 kHz 9" can certainly find both and with my experience with smaller coils it makes me want a 6" DD.
I guess my point was that for me and my type of hunting, I'm not sure I would gain any extra coins with the 3khz coil.
 
Indeed you might not, at least due to frequency. But a 6" 7.5kHz DD might.
Up until we had the "Digger" coil, the 6" HF DD was the smallest DD we had, and many got along with it alright hunting coins in trash, but it was far from optimal.

I'm really thinking that a small 7.5kHz DD would be a hit. I just don't know if there is a reason that we might not get one due to Minelab's already making a 6" MF, even though it's a CC.

I agree that 4.5 kHz difference wouldn't keep you from finding that silver coin. But that 6-inch 7.5 kHz you refer to is concentric, not DD. If we're comparing small DD coil designs, we have two choices at 6-inch.....3 kHz and 18.75 kHz. And the 15.75kHz "spread" between those two will certainly provide a difference in the target's audio response.
As I've said many times in the past, any of the three frequencies are capable of finding anything metal. The primary difference is the audio response you get from the target. The lower frequencies are going to give a more stable audio response on higher conductive targets (silver and copper) than the higher frequency coils. And the higher frequency coils are going to provide a more stable audio response on lower conductive targets. And due to design characteristics, DD coils will separate targets better than similar sized concentric coils. Again, any of the freqs will find any thing metal..... some just make it easier to "sort out the sounds" than others. Different tools for different jobs. JMHO HH Randy
 
Well Randy,
For the most part I like to hunt for old silver coins. I always hunt for gold coins but, since I've never found one in 40 years I consider the silver to be collateral damage. Haha.
Our soil here is quite mineralized and I think the DD would suit my needs nicely. I have a small DD for my Tesoro and like it. There was a small coil for sale on the accessories forum, but not the LF.
I was cringing at the idea of spending $200+ for the digger coil, but as Old Longhair pointed out, I can think of it as getting another detector at a lot less of the cost. So, after Sturgis I will try to get one.
I so thought I was on my way to one with the BH gold ring I found last Saturday till they told me it wasn't real.
 
I went down to the trash infested site for a bit on Saturday. I took the advice of others here and hunted in AM. It was a little hard to get used to at first, so many targets. I moved as slow as I could remember to move and listened for solid repeatable high tone signals. I dug a ton of junk. But I was still able to pull another wheat and Merc dime out. I am confident that the others that have hit this went through with discrimination on and have missed many good coins due to masking. It is a learning process for me, but I think the more I get down there and work at it, the more I'll find. It has the opportunity for a gold coin.
There is probably 300-400 acres of empty lots to hunt.

Great finds and thanks for the tip.

Awesome Bill! Sounds like you are getting a great feel for the new Xterra! It's alot of info to digest with all those tones, but once you get a feel for it, I would never go back to disc'ing (unless maybe at a tot lot). Crazy stuff for me, after coming from one tone!
 
Yea Scott, I'm liking this machine. I just wish it was as light as the Tesoro, but every time I find something good, I forget about the little bit of extra weight.
