I have a new mxt pro, its been 3 month's now and its driving me nuts .I cant seem to get much depth with the 950 eclips readings all over the place .I found ton's of stuff with my first whites Metal detector it's a clasic 5 I D . I went through all the settings ,used the preset's ,gain up ,gain down .dis.up .dis down .anyway it just seem's that for all that money it should at least be as good as my three hundred dollar clasic. also have the 12 inch 300 coil and thats realy no good unless your in realy low trash . all air test are good with the 12 inch but with the 950 no depth maybe 2inchs .outside test in the dirt , nothing . only if it on top then readings are good .do i send it back or im i doing something wrong.can anyone help. Thank's

Does the 12 inch coil seem to work ok outside? It sounds like a problem with the 950. Since its new and you only had it for 3 months you should send it back to get checked out unless you figure out its just the settings. Do you have anything between the detector and coil such as a DX-1 probe? If so, make sure the DX-1 switch is set to 'coil'. Make sure the connection on the coil coax is tight and you have fairly fresh battieries. When you first turn the detector on it shows the battery voltage, if its above 10 volts you should get very good results but I experience erratic behavior when the voltage is under 9 volts(chattering, ect). It doesn't warn you about low bat until it reaches 8 volts. Another cause for erratic behavior is electrical interference in houses and some electric wires above or below ground outside. If you find a spot where the 300 works good, generally any coil, definitely the 950, should work good in the same area.
Can you tell us....?
What mode you are using. (C/J, Pros, Rel)
Sensitivity setting.
Trac switch position. (salt, lock, ground) The ground balance could be causing the loss of depth that you described if the detector is GB'ed incorrectly or set to salt or lock and not GB'ed at all. If you do an air test while the trac switch is set to ground, the detector will constantly null out the target you are testing with thinking it IS the ground. Do you fully understand the ground balancing methods? If you turn the detector OFF and move the trac switch to LOCK, then turn the detector back on it will automatically set and keep the ground balance at a generalized setting and you can do your air tests. Otherwise it is quite difficult, if not impossible, to do accurate air tests with no ground. Keep in mind, it still will not be GB'ed correctly. If you suspect the GB could be causing the issue outside, let us know and we'll explain more about GB'ing and the most accurate way to do so. You may already know all about it but I can't tell by your post.
Trigger position. (center, forward)
Treshold position should be set where you barely hear a faint tone all the time.

It sounds like the 950 coil is bad and you might not have to sent the unit in. Just call White's and explain your problem, they would most likely send a replacement coil.
Thanks for your advice and sorry i did'nt explain the prob. in full. So here it is, Ill take the pro to a park of some kind and with the 950 connected all tight.ill flip the switch to c&j set the dis. to just above the preset at about 4 the other switch to ground. turn it on check the batt. it say's 11 volts set to preset just about the +1 before i turn the threshold down ill pump the coil get ground balanced then lock it .turn the threshold
down so i can just here it.Away i go sweeping just above the ground.I like to use the tone ID on i find it easy ,so i here a lot of beeping ok its a trashy park .Ill get a strong sig.sweep it, check all the readouts looks good .Dig ,2 inches its a nail. vdi 73 penny -dime . To be fair sometimes its a dime .and 25 cents always on the money.never deeper then 2-3 inches.S0 i try +2 and a little more dis.no change in depth .so i move it to relic G B agan lock it and move on always the same .So i took the Pro home went into the backyard dug some holes 2inch 4inch 8inch 12 inch tryed all the setings with coin's ring's trash brass . The reslut is that i get no reading below 3inch's on anything maybe some faint chater. at 3inch or above it works fine .Now in this same yard with my clasic 5 a 350 dollar white's, I have pulled coin's and all kinds of things out of this ground at up to 11 inches.and on the beach it paid for it self the first time out .with a gold weding band and a dimond ring.So im thinking the mxt has to be better, NO? Not so far. I was thinking the coil was bad but last night i did a test i saw on youtube with a copper and a zink and it worked just fine .this was and air test .So there it is my friend's . and thanks agan for all your input .

Are you saying it airtests ok with the 950 using a penny? You said it worked just fine with a test you did last night, is the 950 airtesting ok but not getting any depth in the yard? If so, its possible that the 2 detectors(mxt vs your old whites) are using different frequencies and the ground is really hot, high mineralization. To check your ground phase, pump your coil and LOCK the TRAC switch, then switch to the PROSPECTING mode and check to see what the ground phase is. In the below picture the ground phase is 54. If the ground phase is very high, the detector loses depth due to ignoring the mineralization.

Since the park your hunting has alot of trash, very typical, Its almost expected that you will find surface junk that VDI's incorrectly because of junk under the junk. For example, I dig alot of pulltabs that VDI higher than they should but once they are OUT of the ground they VDI spot on. If they were in perfect ground with no junk and mineralization they should VDI correctly whether in the ground or not.
How does the 12" coil air test for depth compared to the 950? Sounds like you know all about the GB. I always use tone ID as well, it keeps me from having to stare at the LCD screen.

Ok ill check out the ground phase sounds like good idea.And both coils air test good ,I air tested outside after GB, not in the house and i do get more depth with the 12inch but its only good in low trash. The test i did with the penny was to dis. out the zink but still pick up the copper.anyway i like the ground phase idea ill try that right away .Thanks for all you help.
Sounds like you saw my video I posted on youtube showing its possible. It doesn't really 'test' the coil so much as shows off the detectors ability. Either way, I guess it does confirm the coil is accurate as far as 'seeing' the difference between the two types of pennies. 
This should not be used in actual use when your detecting. Alot of copper pennies can VDI low and look like a Zinc penny or even lower on the VDI scale before digging. I've dug IH cents that showed as bottle cap, although deeper signals usually read lower on the scale. Plus, IH cents read lower than new copper pennies anyways. Its best to run the disc as low as your tolerance will allow and judge what signals are worth digging. If your still learning the detector, you might want to get away from the trashy park. Thats a really challenging area to hunt, besides the good targets are tough ones. They are there but you will have to hunt there when you are confident with the detector, otherwise you will quickly lose that confidence right now.

Oh and i was using the 950 when i did your test.thanks agan .Dalton
I hope it works for you now, but remember to find a clean area to ground balance where you DO NOT hear any targets. Otherwise, you will be ground balancing on top of a target and the detector will null out some of the signal. The ground balance makes the detector ignore some signal(mineralization), you don't want it ignoring the good stuff.

Bad coil send the whole thing back and they will fix it right. My excellerater 8" get really good depth on nickles.
