Please help lost X-Terra 70 user

[Grant]

You all seem to know your stuff about the X70 I just got mine two weeks ago At every turn or change in setting I'm getting worse off! I finally found a deep penny 8+"S but lately everything is 3"s or lower : ( MY XL pro can do that.) I have two coils the 6'DD 18.75kHz the 10X5' 18.75kHz elliptical DD and the stock coil I'm hunting in moderate to sum what higher mineralized ground as the Parks are next to rivers and I've dug black sand 200' from the river! an a lot of area with no ground noise anyway I've tried was skunked today until I switched to tracking with beach mode on and got 8 pennies immediately good right? well they were on the only at 1" I know I'm missing coins. and just haven't come up with a good setting VDI ( just sumps unless target is under 3"S) GB NC thresh hold all together I've been hunting on pattern 1 with threshold at 13 and sensitivity at 20-27 problem was I didn't record or pay attention when I dug my deepest coins. I'm getting allot of faint signals with no VDI an I'm digging a ton of trash simply bcuz I'm unclear if I'm missing something. any suggestions would be great. Just an all around good starting point/ coil to use or buy/ any of you who have had these issues before? at first my threshold was to low for those of you who hunt all around for a little of everything Parks/ freshwater beaches old sites ETC... wat settings do you use? any help would make my hunt tomorrow a lot better and I'm not even sure I'm GB right. thanks so much and good luck hunting!

If you have located coins at 8-inches in the past. Then there is no reason you are not still able to do it, if the detector is working properly. Without offering a whole lot of information that may or may not apply to your sites......... You indicated you are not sure if you are GB correctly. My suggestion would be to set up in AutoGB. If you are using Track mode, remember you can switch off track once you get going. I only mention that because some of those faint signals you are hearing may be falsing. And remember that all your Pattern modes are adjustable. Personally, I like to run in all metal and listen for the consistent tones (other than low tones) If you haven't taken a look at the FAQFAQ section at the top of these posts, I invite you to take a look. Lots of good information there for anyone using the X-Terra. HH Randy

If I were you, I would read the FAQFAQ at the beginning of the X-Terra section. Print out the parts on setting your detector up. Take your detector out, with the directions in hand and follow the directions on ground balance, noise cancel etc. It's possible the area you are detecting in just has junk, but not many coins. Areas with a lot of junk are not good areas to learn in. Try some areas where you know people have been, but don't have too much junk in the ground. I think that if you just follow the directions, it will all come to you in a short period of time. The 6" coil is the best to use in areas with a lot of junk. Areas with a lot of junk will drive you crazy until you get to know what the detector is telling you. Give that a try and let us know if you are still having problems. Don't give up, it will come to you with practice. Once it does, it will be like second nature as far as set up and being able to discern what the detector is telling you. If you know someone else who does a lot of detecting, see if that person can go out with you and help until you figure out the detector. The first time I took my detector out, I had problems. I printed out the entire FAQFAQ section and took it with me. Within a short time, I was making good finds. When I got confused or unsure if I was doing something right, I just referred to the print outs I had with me and it answered my questions. You should also make a coin garden and put coins in the ground at a couple of different depths. Listen to the signals they make and note where they fall on the scale.
Try starting out using pattern 1 and use 2 or 3 tones. Once you get used to the detector in that mode, you can start using all metal mode and experiment to see how many tones works the best for you. Dig everything at first, but be sure to note the sound and number on the display before digging. You might get tired of digging junk, but it's one of the best ways to make the connection between what your detector is telling you and what the object under the coil was.

Good hunting, John K

Aslo My VDI reading are way off nails are comin in at a constant 42-46 if under 4's the only constant VDI I get right is surface stuff! but Iknow it works had that penny come in at 30/32 at 8+'s should I ignore the VDY and listen only I can't ingnoerw the faint tones or change in VDI'S on deep targets bcuz that's what I'm geting in the feild. 44 an 46 seems to be junk always if down deep

 

[rifleman]

Iron and nails will read in the high 40's as well as the minus numbers. You should be hearing the low tone when it's iron or a nail. One of the written articles described the scale on the 70 as being circular. Once you think of it that way it makes sense.

Good hunting, John k

Thanks Digger an John! you guys always get me back on track I think I just get too excited holding this machine and seeing what everyone else is finding and getting to jumpy. 1st I need to get to where the older coins are and second learn my targets or Vice versa! I mean. I'm printing that section out now. In fact if I remember correct I had one time in my hand when I found the deep coin. again thanks for your guys specially you John you've taken a lot of time out to help me. I'll send you an old coin if I find more then one promise! gotta find two of the same though! LOL Our river here is the Columbia river and there been many Spanish ships that have came though the Ft. Vancouver. I've always thought that would be an great area the actual Ft. is blocked off your not allowed to detect but all the river has turned up is new coins and 1,000 pull tabs in not drinking parks!

 

[rifleman]

Your welcome. I hope you find some of those old Spanish coins, gold preferably !!!

Good hunting, John K

I bought a 70 about 2 weeks ago and have gone on several short hunts. The last time I used it, I could not get a smooth threshold tone -- it was kind of wavery. I still found targets, but it was kind of distracting. There were two overhead electric lines nearby, but I never got closer than 50 feet to either one of them. I did an auto noise cancel and it chose -1. I also adjusted noise cancel manually and tried all the settings, but they all sounded the same. I tried reducing the sensitivity setting, but that didn't seem to help smooth anything out either. I also did an auto GB, then tried a manual GB, and then tried Tracking GB, but no difference on the audio. Can someone or several someones give me an opinion on what was going on and what I might try differently? Thanks.

As a newbie to the 70 myself I wish I could help more I did run into an issue with a powerline but moving around 20' away and A GN took care of the issue I think although I've never heard a completely smooth threshold from the 70 just a mix of highs and lows which I've been told is OK. maybe try to GB with the coil held out straight from your waist this is the way most machines are ground balanced. Not sure sorry? Grant

 

[Digger]

The threshold tone is a synthesized tone that (in my opinion) has two purposes. One is to let you know the detector is operating. And two is when it blanks out over rejected targets in a C/T pattern mode. In either case, it is not required to be a solid consistent tone. In fact, most prefer it to be a slightly audible "background" hum that does the two things I mentioned. Although the tone you get from a target when detecting must overcome the volume of the threshold tone (to be heard), it is a totally separate tone. The pitch of the threshold tone is only adjustable in the Prospecting mode. The C/T mode threshold tone has a preset frequency. JMHO HH Randy

 

[Cliff KS]

OK! Thanks for the input Digger. I guess I shouldn't worry that the threshold tone is not as smooth some days as others as long as I have no problem hearing target signals above the slightly fluctuating threshold tone.
