We've spent a lot of time here lately on whether to X or whether to CoilTek.
We don't know if we should Z or Q.
We have so many choices we don't know what to do.
Make life simple and get the app:
This might be easier. Forget the coils and forget the manufacturer. 😁

The black stone is pure magnetite. The purpose of this prototype is discrimination that can indicates very deep targets such as for digging . So far all very deep targets were missed , as well as non-magnetic targets are indicated by discrimination like magnetic (iron ) . The prototype was tested on sand of pure magnetite and can be used to search for golden nuggets , while at the same time rejects the shallow iron objects . In tests on different soils shows very low soil noises , and almost complete absence of false signals . There is a video with the same prototype in youtube , from October 2018 .
I’ve been hunting a good site using the Deus and Equinox which has nails and small iron mixed in with good targets, some good targets being deep, but near or in the iron. My question is, will a GPX with Iron Discrimination turned up and the smallest DD coil pull out the deeper, non-ferrous items amongst heavy iron? Has anyone had any experience with this? I think for shallow targets the Equinox or Deus works better for shallow targets in this “machine gun iron”, but would like to see what others may have insight on for using the GPX. I’m assuming the fast setting and special soil timing may need to be adjusted as well. Thank you in advance.

Here's a video i did of the X Steve
Sorry its so long but tried to get in the attributes in under a hour LOL.
50 gain and threshold 40 all potentiometers go zero to 50..disc point is where it just drops out
Indian Head 13"
Z Penny 13"
Copper Penny 12.5"
Clad Dime 12.25"
Silver Dime 12.25"
Silver Quarter 14"
Half Dollar 15.25"
Silver Dollar 16.5"
.58 Cal. 3 Ringer 13.5
C.S.A. Rectangle 23"
U.S. Oval 25"
Breast Plate 23"
DISC POINTS WHERE JUST GONE
Indian Head 38.5
Z Penny 39
Copper Penny 43
Clad Dime 44.5
Silver Dime 45
Silver Quarter 46
Half Dollar 48
Silver Dollar 50 still solid
Coke Can flat 45
Square tab 34
The X has very good Disc actually a sweet disc its gone when its gone on the dial just today I set my second disc on 38.5 to low/high tone a .58 caliber three ringer and hunted in a trashy area and picked some deep 3 ringers out by checking on second disc and if the tone was flip flopping I almost KNEW it was a bullet!!
You can set the 2nd disc to break up (flip flop from low to high tone) on a target which I like for exactness or silence the target or accept etc..
If you dont want to hear a low tone for disc'ed items just turn the iron volume to zero.then its a single tone with full disc on either first or second disc.
You can use both disc to create a notch window if you like to your exact requirements say nickles.Set first disc right below nickle and second disc right above or on edge of breaking then you have a user defined notch to check a target with .
You push trigger forward to use second disc and pull for a all metal no tone accept all mode like a pinpoint.theres 2 triggers for either right or left hand operation.
Machine is on 12 Volts with Drop in battery holder like say a Infinium with quarter turn door.
The Gain control is the receive gain.A amplifier for the returned signal and can be tweaked for hot ground or more benign ground
The Threshold is the depth/target size control and decides how weak a signal you can hear the lower you set it the more signal it takes to break though the higher you set it up to a point of say 45 the less signal it takes to over come it.even in deep woods EMI free areas you will overdrive it into instability as a sizzling chatter..Im running it right on edge of sizzle for best depth and even smallest of targets.
The I've dug no big iron with the X since running it now about 25 hours.Even in my big iron sites.I hear it but know its iron by the way the tones sound even n just nail reject.of 20.And picked brass out of the sites of all shapes and sizes.
Crown caps also sound ratty.
The knobs are very tight and you can set them and wont bump them out of tuning..One thing to show the exactness of the disc is I can cancel a flattened beer can and still hit a Quarter Clean
I’m venturing into the spotlight here with my first post to ask what likely amounts to a novice’s question.
It stems from an experience I had about a year ago with finding my largest nugget. The location was in a small creek bed, which had been conveniently cleared of cobbles and overburden down to a small patch of bedrock surrounded by smooth, silty clay by a dredger.
Using a GM 1000, I had detected out several small nuggets from within the bedrock cracks that had been exposed, but not properly crevassed by the prior prospector. However, the thick clay surrounding the exposed bedrock had pockets of varying degrees of moisture.
This was providing me a bit of challenge since the wetter spots seemed to be behaving just like hot spots. After an extended wrestling match with the wetter signals and the available settings, I gave up.
However, by the time the next weekend came around, I just couldn’t get those wet spots out of my mind. With the heat of the summer and record drought conditions, I guessed those spots may have dried just enough to deserve one final pass.
Within minutes of returning, I had found a solid, repeatable, 2 bar non-ferrous signal in the deepest clay pocket on the upstream side of the rock. (This exact spot had seemed masked the week before.) Digging 4-5 inches down into the smooth clay I found a “rock” that made my detector sing. Cleaning it off revealed a beautiful 1/3 ozt. nugget. Call it beginner’s luck—because I do.
Now for my question. Were those wet spots of clay giving me fits because of greater relative mineralization, heterogeneity of moisture, or VLF technology? Perhaps it was some of each?
Part of my curiosity stems from never having used a PI detector. For those of you with plenty of PI experience, do you also struggle with wet spots or mud spots for lack of a better term? And, if so, are certain PI detectors more resistant to the struggle?
Thanks for any input you might spare.

Update January 2019 - I started reviewing detectors on the internet over twenty years ago. At the time it seemed I was providing a service since good information was hard to find. I enjoyed reviewing machines in detail for those who were interested. The internet was more friendly back in those days.
Times have changed, and these days everyone with a video camera is a metal detector expert. In particular there is a trend where industry insiders like me are considered tainted sources of information, not to be trusted. Personally, I don’t need people questioning my integrity. I was doing this for fun and that sucked all the fun out of it. I am therefore no longer accepting invitations to test or review metal detecting equipment.
That said, my thanks to those of you who have expressed your appreciation for my efforts over the years. You can find my collected detector reports here. The focus on this website going forward will be individual user reviews as part of the new Metal Detector Database with User Reviews. Check it out!
