Depth?

Active member
I read a post here recently where the poster said he was finding newer coins at 5-6 inches. Another member told him that the silver coins may be out of his reach if newer coins are that deep.
My question then is, what is the expected depth of a 705 with the stock coil?
Thanks for your answers.
 
Depth is relative to mineralization and size of object and composition. Sure a detector can go 12 inches but can it ID that beep? I can barely get dimes at 5-6 inches with stock coil with GB at 20-25. Now that is with a true ID. I am probably missing dimes then that might be at 8 inches. This is the reason that a lot of people listen for those faint whispers. They are telling you something.
 
I have found clad dimes at about 8" with the 6" MF coil, 6-7" is very common for me. I always run max sensitivity when conditions allow. I imagine the stock coil will hit much deeper than the 6". The X-Terra 705 is known for having very good depth. Also some say that the clads actually sink faster/deeper than the silver coins. You have a great detector there Bill, It's a machine that definitely inspires confidence. Just learn it & trust it, and you will be posting more of your great finds on here real soon! I'm sure you have probably already downloaded Digger's e-book from the ML website, but if not, it is a must read & very helpful. Keep us posted Bill! HH
 
Hey guys, I was just curious what others might think about the depth thing. In all honesty, I may not ever have to worry about THOSE kind of depths where I live.
As you know Scott, I'm enjoying the finds I've been getting lately over my other detector.
 
Around here, I've never found silver deeper than about 10". Most have been within 6".
The deepest oldest coin I've found in the last couple years was an 1844 Bank of Montreal half penny token at 13", and the second oldest was a penny sized Civil War storecard token at less than 3" (both copper). At the same time I dig clad from the surface to 8" regularly, and occasionally as deep as 10-11".
 
It really depends on the site Bill. On open clean ground, my Explorer SE w/18" loop gets as deep as anything can go, but it's size limits it's usefulness if trash density is up. With a comparable coils the Explorer and Xterra run about even on depth. Most often the Xterra is my go-to machine. It's lighter, faster, more stable, and by being able to select just one detecting frequecy it can run where the FBS has trouble w/o sacrificing sensitivity. I like the ability to have more control over GB that the Xterra affords me too.
 
I'd you're finding coins at some of those depths with the Xterra, I'm good with that.
Thank you.
 
Bill, their is no expected depth with the Xterra or any other MDer for the reasons that " Goodbaja " stated. I only use the 10.5 DD MF coil and like I have stated before that I have found IH's, Barber and seated dimes before as deep as 12" but that was in what I call perfect soil and plz do not ask me to explain what perfect soil is, lol. After you have been using the Xterra for a year or so you will know it when your at a place and the xterra will be able to pick up a good signal down a good 8" and deeper.

Another thing,,, do not expect to get a good ID on ANYTHING that is deeper then 4" if you want to be finding old coins. If you want to find deep old coins then you will need to be digging some of those deep iffy signals. It's not very often that you will get a good ID on a old coin that is deeper then 6" deep. If you want to find the old Buff's and V's then you will be digging signals that have the numbers jumping all over the place,,,, but it's the TONE that get's me to dig...... Last year I found 15 V's and 43 Buff's,, I dig a lot a iffy signals. It's rare that I get a perfect signal on any old coin I find.

Excellent explanation Mark! It's no wonder 99.9% of the coins I find are clad. I have been concentrating on those "iffy" signals which leads me to dig deeper, on my own lawn for now, but I know sooner or later I'll start hitting the old stuff. I've also been going back over the same areas & digging signals that are a mixture of high & low tones but with the majority of tones staying on the high side(46-30).
 
Most of the time I hunt by tone, even my beep and dig detector with one tone can speak volumes. I do look at the ID when I get a good signal but, dig them most of the time anyway.
I wouldn't think to ask about 'perfect' soil however, I'd like to know what you consider iffy. Sometimes my signals have "that" sound but only are good when you work part way around them, so I dig, some are good some not.
Lately I've noticed when hunting for a couple of hours, my good tones sound scratchy. That's the best I can do to explain the sound. Almost like I have a speaker problem. Its not a problem, just an annoyance.
 
The scratchy sound could be that your wire on your headphones is getting bad at the plug. I've had that problem alot. put a new 1/4" plug on.

It's really hard to explain what a good iffy signal is and what's a bad iffy signal is , it changes every place you go to. That's why when I go to a place for the first time I like to dig everything the beeps for the first half hour or so to get a feel as to how the xterra is reacting " sound and numbers " to things in the ground. Do not get me wrong,, I dig a lot of TRASH when I am chasing after those iffy signals but some times the pay off is great with finding a nice old coin. Also, the tones play a big part in if I dig or not a iffy signals. but keep in mind, your tones will not be perfect either. It takes a long time to learn how to deal with iffy signals.
 
If you run a bit hot you will understand what iffy sounds are like cause of depth and you need to raise up. I found two silver coins at 10'' in a site i could run the detector with almost full sensitivity 18 sen for xt505 and a copper piece of metal coin size at 13''. Tone was low but has the habit that wants to jump to high when wiggle. Xterras are the only detectors tried so far with this excellent way to discriminate with the sound of a target and not the tone. I hunt always with the 10.5'' 7.5 freq.

Good point, but I don't believe the wire on the headphones would cause signals to be scratchy ONLY on higher tone quarter signals, and not on any other signals across the whole spectrum of tones. A bad plug would probably be scratchy on more than just one tone frequency.
 
I think I know what you meant by scratchy, ''breaking tone'' could be any of targets like roundish iron as a guns shell or a good target next iron and you can hear of course both but with this manner or especially a deep coin and causing it break from high iron mineralization.
