I got an xterra 505 for christmas this year and ive had the ability to go out detecting three times since. I feel like Ive got a good feel for this detector and was wondering if anyone used the same machine and had any tips. The thing Im most concerned about is how accurate the target ID chart I found on here was. I havent found much outside the normal clad coins one might find, and was curious if anyone could either offer me a better list or clarify that this is indeed a good one.

I would think it should be fairly accurate, that list has been on the forums for along time. Do some bench testing with your 505 using various coins and see what id they come in at. Soil minerals,depth of the coin,corrosion,coin tilted in ground, junk target next to the coin, all affects target id on any detector.

Here is a big tip....these numbers on your machine are indicators, not gospel.

I have the same kind of list for my F2 and I know the numbers pretty well by now...but I don't believe them for the most part.

Nickels on that machine should be a solid 33, but I have dug plenty that are higher and lower.
Tabs usually come in at tab numbers, but not always.
On my Tesoros, there is a discrimination knob that points to what they think you are scanning.
Turn past this point and the signal goes away.
Do I think this is accurate?
Well yes, sometimes, but every time...noway!
On all these machines I have dug coins all over the place, tabs way above and below that tab mark, and all kinds of things that did not fall in line with any of these "numbers".
Those disc knobs and screens can't possibly take everything into account we have to deal with in this hobby.
Soil conditions, depth, moisture, how the target is laying, proximity to other metals like trash or even other coins all will affect your readings.
Heck, sometimes it seems like even sunspots, temperature and even the color of the socks you are wearing that day affects our machines, too.

Now I know we are talking about coins here but you also have to realize there is other metal that comes in all over the place, metal that we love to find, and those disc knobs and screens can't possibly tell you everything you absolutely need to know about a hidden target.
The only thing that can is X-Ray vision or digging that target up and looking at it.

In the last year I have been lucky enough to dig up 3 great things that lots of other hunters that have hunted for decades were not as fortunate to find.
One is a very large and rare token that there are known to be less than 5 in existence, and 2 large 10k gold class rings that total 31 grams between them.

All three of these targets were absolutely 10 ways from Sunday a solid for sure zinc signal, and they would have been the same on every detector in existence...but they weren't zinc pennies, a coin that many hunters avoid digging..

I am a huge advocate for digging it all...or most stuff anyway, even the trash, no matter what machine I am swinging.
Lots of very successful hunters here, coins and otherwise, but ask them about their trash pile.
Nobody believes these numbers 100%, you shouldn't either.
Just use common sense, learn your machine well as you seem to be doing, and take every signal with a grain of salt and you might end up digging more trash, but at the end of the day you will also dig more treasure.

I have seen your finds and you can find that silver, and I see you can find gold too, that's great, just don't fall into the trap of cherry picking everything because you think your upgraded detector is so super duper accurate...more than your first.
It is, but you still never ever know what you have 100% till you dig it.

With an X-Terra, it also depends on which frequency coil you're using.

The MF (75.kHz) coil has very even and consistant target bin widths, so in average soil conditions those ID #'s will be close.

With the HF (18.75kHz) coil, the bin widths are narrower at the top of the scale, so highly conductive targets (copper, silver, aluminum, rust, etc...) can bleed over into adjacent bins, making the values on that chart a tad lower than normal. However, on lower conductors like gold and nickel, will be more accurately ID'd due to wider bin segments on the low end of the scale. Jefferson and buffalo nickels will always be 12.
 
I've had this machine for 3 years and have used that same chart as a guide with success. However I recently downloaded a using your xterra ebook from minelabs site. After following the tips there its like a whole different machine.

Word of advice learn the tones and dig solid repeatable tones regardless of the number at first. This machine has found me more old coins then I thought possible can't say enough good things about it.
 
The list is pretty close for my x-50, if the tid repeats (good number) from different directions I always dig. From one way gets a little tricky.
 
I have the xterra 50. The chart is ok for a referrence but I rely mostly on the sounds. Or more to the point the consistancy of the sounds when the coin is swung over the target from different directions.
As usual, the pull tabs and nickles will sound pretty much the same. But again, when swinging from different directions the nickle will be a little more consistant in the sound and numbers. Having said that, I still have a HUGE pile of pull tabs. Just waiting for aluminum to go up. :roll:
 
dont forget the whispers
i dug a war nickle at 9 inches that was just a slight little whisper but repeatable

That free e-book (written by Randy Horton) should be on every X-Terra owner's computer desktop. I can't recommend it highly enough!
