I have been spending so much time getting comfortable with the ACE250 I neglected the MXT. I took it out to day to a small park about twenty miles from in. It

Sounds like you've got a great spot for detecting. YES, by all means dig those weak signals. Those "weak" signals are deeper targets and more than likely NOT can slaw. Usually aluminum doesn't go deep into the ground like a silver coin or older copper coins. Good luck and keep us posted.
I'm sure others have ideas also. We've got a great group of people here.

I agree with Nancy about the weak signals. Some of my deepest coins are weak signals that won't lock or will only give an audio signal. When I check and it says 10 inches or more I get excited.
I would think a ground reading in the 60's is pretty good ground. From the MXT manual, GND readings in the high 70's and 80's are considered heavy iron mineralization. Higher numbers simply mean predominately ferrous (iron) such as black sands / magnetite.
Lower numbers simply mean less iron and/or predominately conductive nonferrous (not of iron) content, such as gold per ton of rock. I've never had to run the gain as low as 4. You would be losing a lot of depth. I remember Monte ( he has highly mineralized ground) say he never had to go below a 7 for gain.
If there is a lot of decomposing metal (nails) in the ground, ground balance on clean ground and then lock the Trac.
I can get aluminum twist caps or canslaw to read in the .01, .10, and .25 cent range put never tabs.
If you sweep slow with the 5.3 coil you should be able to read the good targets. I hunted an old site where there had been aluminum siding on the house. Now that was bad. Good luck. Rob

Hummmmm.
I'm going back to that park again and check out that ground reading while I'm at it because I kept getting lots of hot rocks. I may have mis read the ground reading. My memory plays tricks on me sometimes

Yes, I will look/listen for those weak signals and dig and keep you posted.

After properly ground balancing on clean ground, put your ground switch into the "lock" position. Run your machine in "relic mode". Better overall performance in relic mode. Put the trigger switch on your handle in the "forward" position and leave it there. This will give you two tones........low grunts indicating iron or ferrous material, and a higher tone indicating anything non-ferrous or non-iron.....same thing. You shouldn't have any problem running your gain at a minimum of 9......likely even higher. I consistently hunt old, trashy sites in mineralized soil (in the 70's) and I run mine in the +1 to +3 range......always. Greater depth with higher gain. It wouldn't hurt to turn your "disc" dial to a hair past "nails". You won't miss many good targets just past nails and it'll quiet your machine a tad. MXT's tend to be a bit noisy but they're excellent once you get accustomed to them. Turn your "threshold" to a slight hum....that's all you'll need. Many great finds are recovered in trashy sites. Patience and practice are the key words here. When you get a high tone sound, try and isolate your coil on that target. Not always easy to do in trashy areas but if you're getting a high tone amongst other trash, dig it ! Your VDI number is always the same in either mode you hunt with, whether it be relic or coin/jewelery. Trust me when I tell you that relic gives better overall performance. With some practice, you'll develop your hearing. By this I mean that more often than not, you'll learn to distinguish a "likely" coin as opposed to garbage metal such as aluminum siding. The good targets give a crisper snap at the beginning and end of each signal. Having said that, still dig the other signals if the VDI number is attractive. 30's are generally junk (for the most part), 40's will surprise you occasionally and anything higher, ALWAYS dig. The mid teens to mid 20's is where you'll find nickels....or gold. Lots of pull-tabs and trash dug in those numbers as well so decide for yourself. As a side note, if you're hunting an early military site and are looking for relics and buttons etc., you virtually dig most everything. I do that as well.....and leave my "disc" at zero. Hope this isn't too much info......it'll save you some precious hunting time with much better results. Swing your coil slowly.....slow wins the race. Good luck bud !
Rob.....there are some other variations but what I've posted here is a good rule of thumb. I'd say it'll be effective under 95% of the conditions you'll likely face. The deep targets are always worth checking out.....any serious hunter can testify to the fact that abundantly more garbage is dug than good finds though......just the nature of the game.
