should the high pitch beep be repeditive or will it break up a little on deep to mid range depth coins and where should the cross-line be,on top to the right for coins?
Well first on the sound. It will be far fainter on the deep coins. It will sound far less distinct as well.
They will generally repeat in two ways (say 90*) but not always.
The cross-hair will be anywhere in that top area depending on many things. If you counting on it to tell you what you think it is don't. Use it as a reference only.
Many and almost all my deep silver coins will hit high mid (sometimes left of mid) then bounce right and or right and down, but that is something you will learn and get used accustomed too. They very best way for you to experience this is find someone that is using a XS, XSs, XSII or SE and tag along with someone with experience. Let them find some signals for you and let you listen to them.
Another thing you could do is go to a coin store and pick yourself up culls (cheap none numismatic coins of little value) of various coins and wave them under the coil and watch and see where that cross-hair goes if you want. Then move them to extreme detection distances from the coil and watch what happens. Be sure to lower your sens. in-house to about 8 or so or that cross-hair will be going everywhere LOL.
I would also type in some things here and read them. Type in Warble, Cursor Bounce, just for starts.
Andy Sabisch puts out some good reads I hear on the XS line so, that may be great for you as well.
One thing I cannot express enough is learn the tones not the placement of the crossshair. If you count solely on that cross-hair to stick in one spot you might get some 7" Large Pennies but, chances are you will pass up things like a worn 10" Half Dime or nice Seated and all the deep keepers etc.
I will give today's hunt for example. Almost all my wheat's where deep and I mean deep. My buddy (although my hearing is far better) I honestly do not think he could hear them. They where so faint and the cross-hair was skipping all around the top.
But, the tone although faint was still there. The tone was key to finding them.
Also: for gold and nickles,will the tone be low and where will the crossline be?
Nickels and for the most part Gold will have a much lower tone then Coppers and Silvers. If the biggest difference for you is tone variation go into your menu and put your variability's to 10. That basically gives you the broadest variability in tones. I have not played with my SE Pro enough (its been collecting dust) so, I am not sure if it has Audio 1,2, and 3 like my XSII does and if so that can help you separate the tones even further.
I personally use Normal Audio on my XSII and Var. at 9. If Deep is off I would turn it on. I leave Fast off. My gain is at 7 (Fac. is 5) on my II but, factory is 8 on the Se Pro. There are many things you can adjust to your liking and preference but, do not worry about to much about all that now as that will come and there is no sense in bombarding yourself with to much too soon. I am also a Fer. Tone hunter and we won't get into that as that is a whole different story all together and a matter of opinion. Just taking off in the Factory settings should be fine for now for you. I was only giving you some input.
Nickels will sound in tone deeper in tone. A 2" deep Nickel is not going to sound as distinct as a 9" Shield Nickel. Once again it will be much fainter. Well, unless you crank your gain (amplifier) to max. (just kidding don't do that) at that point everything would sound so much alike in loudness and then you could never discern a deep coin from a 5" coin.
As far as where they typically fall. The Cursor will generally sit on the very bottom of the screens with the box sitting on the line (as a rule of thumb) right of center. Deepies once again will skip across that line quite often.
Gold!!!!! ohhh she is a whole different beast and it hits in so many places but, most fall into junk area and if you want to get Rings etc you will be digging junk but, that is the way it goes. Doing it takes patience but, you can and will be rewarded over time with some nice Rings. If you want to see where just a fraction of where some Gold hits go get all yours together or ask to borrow your wife's or families Gold rings and start waving them around the coil.
One thing to consider there are plenty of times you will get a tone that just is not the norm and if you glance at your Smart Screen and it just does not seem to fit the usual and is deep dig. I dig most everything that is deep and circles small if there is any question but, what i am saying take today's hunt for me. If I where to have relied on my S.C. to whether or not dig the cursor placement on the Buffalo I probably would not have. Why? because it was a low wheat hit on the screen being combined with the Buffalo that was in the hole with it. It was the tone that warranted the dig and not the screen. The cursor really did not say dig but, that tone did and like I stated I circled it. It was small and the depth was deep like the wheat's I had been pulling from the same spot.
Also, Indian Head pennies! Get some of those and listen to them they do not sound the same and remember the fatty Indians are different as well. They also, will not hit the same so, once again that Cursor will not be generally in that top right. The deep ones will skip to the right and down and sometimes right and up. Play around practice, read, dig and make notes, and above all have patience.
You can go to you local coin store and ask for some culls (just do not get thin culls) of the different coins you want to listen to and watch the Cursor. Pay attention to what what happens to that cursor once you get on the fringe of its detection abilities as this is what will play out in the field once again as a rule of thumb..
Do not dig a test bed in your yard it is not really going to work well, unless you want to wait 100 years. Simply drop your Sensitivity and listen then watch the cursor on the fringe in house. People wonder why the coins they plant in their yard are not detectable and it's due to the (easy way to put it) the Halo Effect and the reaction of Coins/Objects in soil.
Do plenty of searches here as this place has so much Information garnered over the last 10+ years you will probably find anything you need.
Just take your time and have fun learning the machine and dig those deeper hits always listening and making a metal note of what it/they sounded like. You will be rewarded. Use you screen as reference not as the dig indicator.
Circle your targets and verify their size that will help a ton. I personally go in circles with real quick flips of my XSII once I get something that warrants further investigating. Just listening to what I hear. Then I might glance at my screen.
Also, go SLOW this is not your Fisher.
When I say Slow I would say if your sweeping a 2 foot wide swing path area count 1 thousand-2 thousand- 3 thousand and you will be where you started. That is just a place to start and sometimes I go way slower if not almost to a creeping halt slow.
Keep that coil flat smack stuck to the ground also.
I did not have anyone to show or teach me (got my first XS in 2000) but, I made it and if I can do it anyone can. I then I taught my buddy to use his 10 years ago (once i talked him into ditching his C.M.).
My best help( short of just using it) was here many moons ago and it is where you will get all the information you need that you cannot learn in the field.
Best of luck and I hope I was of some help and did not confuse you!
