x50 coil for silver coins

[pike335]

hello all,
what would anyone who has experience with the x50 say is the absolute best coil for hunting old silver coins? i have the 18.75, and the 7.5 coils. i have been primarily using the 7.5 coil with great success on the old silver, but was wondering if the 3 khz coil would be better, or dd elliptical for a bit more depth.
enclosed a few pics of a few of my better x50 finds so far, seated qtr is 1877, seated dime is 1877cc, barber dime is 1913.
thanks.

the 7.5 is just right for deep silver, the other is too low and probally not what you're after........anyhow the low one doesnt work on the 50 anyhow ........dude dont change a thing .......you are on fire ,continue as you were .......them finds are tough to beat......

but I will tell you that there is not much difference between the 3 khz and the 7.5 khz on the XT70, atleast not in my soil. I have found wheaties at a measured 9 1/2" with the 7.5 khz with nice repeatable signals. Will hit the silver just as deep and deeper. HH John

John,

Same here on the 3 Khz and 7.5 coils. Other than one site where the 3 Khz handled the contaminated soil better I see little difference. Only had one hunt with the DD elliptic but so far I like it!!

Did you notice much difference on coin depth compared to the 7.5? Thanks....

the seperation in iron is much better than with the concentrics. I was a bit surprised that I could not run the sensitivity higher than I could with the stock coil in the iron at this site, but that may be due to the higher frequency of the DD coil? Anyway, in the short time I used it I got an 1899 IH, what looks like an early general service button and some other odds n'ends from a pretty well hit small area.

I have been sticking to the fields the last few weeks due to the dry conditions, but we finally got some rain and I hope to make it to some other sites this weekend.

Pike,

Testing the Terra's on an almost daily basis (7 days) my silver find rate shot up and I had a great run as I picked the sites carefully - those which were more likely than others to reward with what I wanted.
Even on areas I've hunted before for many years gave up the silver!
The shillings bottom of photo came from a woodland path that I've detected before....they just "jumped out" at me with a screaming high tone and readings of 42 from depths of about 7" from really compacted soil!!! They were found with the 7.5Khz.
Now I shoud also say that, in a large area it's virtually impossible to detect over every sq inch of a piece of ground, especially in a wooded setting when everywhere looks the same! But those shillings came from a well used pathway and have been missed by me for years!
The small coins dotted around the photo came up courtesy of the 18.75Khz from farmland - if you have the DVD you will see the field in question when the guys sit on the Land Rover discussing finds.
The hammered silver shilling Middle Row left came from other farmland as did the "crooked silver love token" Middle Row right - both of those fell to the 3Khz and were particularly "low conductive" coins due probably to a low silver content. On Explorer ll they read Fer 08 Cond 13 for the Elizabeth shilling and Fer 10 Cond 07 for the silver Charles ll shilling.
But, you must remember that silver is a great target anyway and should produce decent audio no matter what machine you use!
Most important thing to consider really is the gold - this will respond better with a Hi-Frequency coil. If your sites are clean and free of shredded aluminium then the 18.75Khz could give you up the gold. If your site has a fair amount of shredded aluminium then it might be a tad too sensitive to use and you may be better to use the 7.5Khz.
If you are into Relic Hunting for large deep objects such as brass and bronze you could use the 3Khz coil.

thanks, guess i'll just stick with what i am doing.

des,
very nice finds, any guess on the age of the coins?
most of the areas i hunt are private property, which i get permission to hunt from customers of mine. mostly older homes mostly built in the early 1800's, and they dont really seem to have too much trash. the ground here is not very harsh either, no problems running the sensitivity at around 16, no balance problems either.
been killing the silver coins, finding several almost every time out mostly from the late 1800's and early 1900's, and have been just waiting for that gold one. maybe ill give the 18.75 a crack at the areas where my older silver finds are coming from and see if it can find some gold.
you are right about the silver giving a great reading, they give the same numerical reading as the clad, but almost have a sweeter sound, can almost always tell when its a silver target.
also have found five silver rings so far also, but no gold ones. the only gold i have found with this machine is a gold charm with a small diamond, and two large gold hoop earrings, all with the 7.5 coil. ill have to give the 18.75 a bit more use.
thanks for the info!

very similar to what I have found in my neck of the woods. As you indicated, the 3 kHz coil should be an excellent choice for relic hunters seeking those larger, deeply buried targets. For US coins, I have found the 7.5 to be more sensitive and just as deep seeking. As well, I have found that the 18.75 kHz coil is a bit too sensitive for coin hunting in areas that contain excessive amounts of "can slaw". Although the 18.75 kHz coil is a bit more sensitive to gold and small jewelry items, I find that to maintain stability, I must set the sensitivity level lower than with the 7.5 kHz coil. When I lower the sensitivity, I have negated any advantage I may have realized by using the higher frequency coil. (as compared to the higher sensitivity setting allowed by the 7.5 kHz). For most of my coin hunting at older sites, I find the 7.5 kHz 9-inch round concentric coil is the most stable, and detects as deeply, as any X-Terra coil currently available. (although like many, I eagerly anticipate the introduction of a smaller coil) Good post! HH Randy

Nice to see that you are having fun.Jerry.
