i have a x terra 70 i am having trouble with a lot of noise i am useing a 18.5 khz dd coil i am playing around to see if any thing works better, like the ground balance and so on. When in the field it seems to ghost find alot ive tried to reduce the sens. It picks up metal fantastic like foil and nails and bolts and crap , but when it comes to small gold i think it will pass over them without a buzz [tested] an less its big, i would like some help please
Thankyou David.
 
This one is erratic and seems to not want to find coins. It's a new machine too.
DD 5x10 very erratic.........7.5 real problem..New coil on the way, hope thats the problem, and a little lack of experience.
Depth seems to be nonexistant so far.Not at all what was expected of the xterra 70.Nothing like my stable XLT detector.
In fact using a 5.3 coil I go back over an area out pops the new money (Clad) and pennies. I wonder.......Could I have missed so many.
 
yes my machine is new too, all the info that i read about in the manual and watch on the mine lab web site seems to be too easy if only my machine would work over ground like on the video,if you could hear slight variations with my ex terra you are doing well try finding small objects around the buzz is a nightmare only the metal [iron] ring out strong.

Since both coils gave you a problem I don't think a new coil is going to fix your issues. Is the buzz you hear your threshold? Have you tried your headphones on another detector to see if it's a bad speaker? You might try setting your threshold to zero for now and see if the buzz is gone. If you reduce your sensitivity to 15 does it help? Have you noise canceled? Are you using rechargeable batteries? I'm just trying to help figure it out.
 
The buzz is more like ground noise when detecting there a lot of ghost noises may be the ground is hot, but i have turned down the sens and this helps i do not want to lose depth and targets my speaker is fine,and i am useing rechargables.
 
The high frequency coils are more prone to noise especialy in mineralised conditions. You say you tried turning down your sensitivity, you might have to turn it down even lower. Try running in tracking and reduce your coil sweep speed ( Swing slowly) This gives the machine more time to adjust to the ground conditions reducing noise.Try engaging target Stability mode this will help to reduce unstable signals. To guage whether your sensitivity is too high try pumping your coil up and down in one spot. If it is noisy reduce the sensitivity until it quietens. Or alternatively reduce you sensitivity and gradually increase your sensitivity until it becomes noisy then reduce it slightly until it is stable. Remember turning your sensitivity down does not reduce your depth in noisy ground it can in fact increase the depth by stopping the coil being swamped by false signals generated by high settings. I hope you sort out your problems but I think the sensitivity is the key seeya Neilo
 
What headphones are you using if you are using high frequency headphones you will hear the buzzing noise I do on my machine but I am using 150ohm.Killer Bees. If I am using a pair of lower ohm say 32ohm it is not noticeable. seeya neilo
 
On the Auto-Ground Tracking. The X70 has two different tracking speeds, the "Normal" Coins & Treasure mode is the slower speed. By turning on "Beach" it will track about ten times faster for quickly changing grounds. But just like when this mode is used at the beach, once you find a target, turn the tracking off while you pinpoint & recover the target.

Sensitivity is relative. What one site allows for an optimum, stable, sensivity setting, another site will not. An analogy I like to use is that of driving at night. If it is a clear night, driving with your high beams on will provide the best vision. High beams penetrate the air with little or no reflective signal. allowing you to see far into the distance. However, if it is foggy, low beams will actually penetrate the atmospheric conditions better. Same goes with detecting. Except instead of the "air clutter" created by fog, we are dealing with "soil cluter" created by mineralization or a high concentration of targets. If you provide too much "signal", whether light beams in fog or electromagnetic lines of flux into the soil with a detector, the signal will reflect back toward the source and be counterproductive.

Although rechargeable batteries should provide sufficient power (amps X volts) to the X-Terra, realize that all rechargeables are not the same. NiCad and NiMH cells provide a fully charged voltage of 1.2 volts per cell, or 4.8 volts to the X-Terra. And be aware that the available current will vary by brand. AA alkalines, carbon or non-rechargeable lithium cells provide 1.5 volts per cell, for a fully charged voltage of 6 volts. And the discharge rate is less dramatic with these non-rechargeables.

As mentioned by another, set your Noise Cancel channel for the site. Interference, whether man-made or natural, can create false signals and inconsistent operation. JMHO HH Randy
 
I changed batteries..all alkaline.........all good..........But I am going to back out of this post now..My Uncle who has tons of experience tried the machine..and it has other issues per him..He's working with his dealer as we speak........So I am certain all will be resolved.............His dealer is great....So thanks all I should have waited till a more experienced person checked out the machine and not posted anything....Hey all manufatured products are subject to problems sometimes..Even the best...Stuff happens.........IT will be Resolved..Thanks all.
 
Just a thought.
It's possible that you be suffering from some outside interference. Mobile phones can sometimes interfere with a detector, so turn it off if you have one in your pocket. Are you operating near power lines or another detector?

hi has anybody thought that the x terra sould have a lit up screen for thouse of us that might want to detect in bad light or darkness.
