Which Coil For Old Coin Hunting

[Coin_Pirate]

I have had my Xterra 70 for a few days now. Haven't found much because I have been testing it at a very trashy park here in Ohio. I plan on searching old homesteads for old coins, mostly looking for siver. Can anyone tell me what the best coil/frequency would be to use for my type of searching. Any help on this subject will be greatly appreciated!!

Thanks!

Congratulations on your new X-70. You will like it alot. I bought the 9" 3 KHz which is supposed to be very good on silver but, I really haven't had a chance to really use it yet. However, I have just been killing our local parks with the 6"HFDD. Really great amongst the trash. Good Luck. Don't be afraid to play with different settings and read what the guys with real experience say about the X-70. By the way, I'm not one of them guys. Just starting out myself.

Thanks for the info. I've already gained a lot of knowledge browsing the forum

Thanks!!

one thing I have noticed with my x70 is that deep targets do not always lock on, lots of times there are other items close that affect the VDI number.....I started hunting in all metal mode, and lately have been digging all non ferrous tones, and to my surprise I have found some deeper coins that gave poor reading and signals. I normally use the 9" stock coil, but also have the 6"

I have had the XT70 a couple weeks and have also tried the various coils. For trashy areas the 6"DD coil cannot be beat (IMO). I have also had very good luck with the standard coil, haven't tried my LF coil yet so I can't say which is best. Congrats on the new machine, hopefully you will be as pleased as I have been.

The above is so true.
My most productive spot produces mid 1800's coins and I dig everything non ferrous. Sometimes I find that as soon as I pull the plug on an iffy signal, the signal greatly changes. If it gets better, it's a good target, if it goes ferrous, it is trash. I own all the xterra coils and my two favorites are the 9"3Khz and the 10.5"DD 7.5Khz. I like the LF on copper and silver and it is less sensitive to iron but....the 10.5" i dig deeper coins hands down.

I believe I have 5 of their coils. The elipitical 18.75 is an DD and the 6' 18.75 ia an DD. The rest are CC's. What is the difference? And what advantages are there to each type, CC vs DD? Thanks to all in advance for the help.

You need to overlap swings less with the DD.

When you say you are hunting in all metal mode, and lately have been digging all non ferrous tones. Do you mean negative numbers?

no......... I mean all non ferrous tones (positive numbers) negative numbers are ferrous (iron)
