Greetings all;I just picked up a mxt and tried it out to default settings.I got lots of signals and background noise.Any ideas or thoughts on this.Is this standard with this psrticular detector or does tuning improve with experience. thanks
 
electrical interference, put the machine in LOCK,
and turn your sensitivity down, see if that helps.
If your outside, GB and then turn sens. down. If
that doesn't do you, let us know. Richard
 
Sounds like your threshold may be too high.
Make sure your threshold is barely audible or just a tad under audible. Default settings should be fine.

... that really helped me until I got used to all the signals, in addition to Richard and Johnny's comments. In coin and jewelry mode lower your gain to about 6 or 7 until you can really hear good targets. Then try relic mode after you get used to the sounds of C&J. I had low end Bounty Hunter machines that didn't have threshold, only tones and the MXT frustrated me to death with all the noise until I figured it out. Now I wouldn't part with it.
 
It will be hard to tell exactly what you're hearing without a bit more specific description, but here's some possibilities:
1. You didn't indicate where you were playing with your MXT. If you were out in the middle of a field that was never really used for much of anything, you should expect your MXT to be pretty well-behaved and quiet. However, if you were in a park, athletic field, carnaval ground, etc., then the "lots of signals" you were hearing was anything and everything from foil, pulltabs, cans, coins, jewelry, etc. The noise you would hear then would be normal. You will see endless discussions of different coils to allow us to hunt these 'trashy' sites and better separate all those signals.
2. If you've set Gain and Disc to preset, make sure you've ground balanced according to the manual. Then move your coil to a quiet area of ground and set the Threshold so it's just audible. That will help cut down on some of the noise. In really noisy ground, some people will turn the Threshold just so it's off, or quiet.
3. Understand that in Coin & Jewelry mode, as well as Relic mode with the trigger in the center position, you will hear ALL targets. You must learn the difference between an 'accepted' target tone and a 'discriminated' target tone.
4. If the ground you were hunting has a lot of old, deeper iron, hot rocks or pockets of high mineralization you will hear more noise from you MXT than if you're over 'mild' ground with no targets. Depending on what you're hunting for, you can Discriminate out that iron, but you still need to learn the difference between a good target and an undesirable one.
5. One setting to help alleviate some noise is Relic mode with the trigger forward. This cuts all tones from targets that are Discriminated out. Personally, I've come to favor this mode of operation - it makes for a much quieter machine.
6. The MXT is a great machine, but it is known for being a little chatty, or noisy. As you get some of this chatter, check the VDI display for the reading. VDI's in the negative numbers is indicating iron; hot rocks will show as "Hot Rocks" on your display. In my area, this usually accounts for a lot of my noise.
I hope this helps....without knowing a little more about the situation you were using your MXT in, it's hard to give a definitive answer. HH Sarge
 
That was very helpful Mr. Walters. Where I have been hunting lately there is tons of Hot Rocks, I have been successful at tuning them out most of the time but my threshhold is very choppy unless I really turn up threshhold to the point of high decibles. Any suggestions? Thanks, luv the MXT.
 
What most people do when they get into ground that drives the MXT nuts is simply cut the Threshold just so it's silent. You will still get an occasional chirp here and there, but it's better than driving yourself crazy with the noise. Try posting this question as a new question and see if you can get an answer from Jim McCulloch. He lives near some pretty nasty ground and uses the MXT. He would have an answer how to tune your machine for that ground!
