Put whatever stock you choose into this supplied info..
First test down the barrel of nail using clad dime. Ruler in pic to show nail size and orientation.
Nox in gold 1 passes test speeds 5-8, iron bias 0-1.
Park 2 gives trailing tone off the left.
Deus using elliptical coil fails all freq except 74khz band.
Impact using 4x7 coil passes 20khz only.
I like reporting of Nox better here than Impact though.
This just took the beginning of testing., more later.
Another pic.
Nail suspended two 2x4 thick over clad dime.
Sweeping across nail lengthwise.
Nox 800 using park 2speed 7 nails dime and IDs accurately -25 in the window.
Impact using 14khz don’t like, using 20khz hits but a user has no clue to targets conductivity level.
Deus hits using elliptical Hf coil, no ID at all until I lowered reactivty to 2, and ID here not accurate.
Another test.
Nail suspected above clad dime sweeping down nail longways to detect dime. Notice just one 2x4 thickness high for the nail.
Nox using gold 1 jumps on this dime using speed 7 iron bias 0.
I should mention sweeping all nails previously solo with Nox, even at iron bias 0 quiet.
Park 2 speed 7 hits the dime too not as well (more coil sweep speed sensitive vs gold 1 mode.
Both modes yielded 17 in the meter.
Impact only chirps on the dime, in a site with a lot of iron, a user just might walk right by.
Deus using 14.4khzwas tied up in knots. Fail.
Using 28.8khz is a pass. Better use no reactivty lower than 2.5 though or you might miss.
Deus tests was disc at 6.2 pitch tones.
All detectors ground balanced to concrete sterile steps.
No trick boys and girls.
I just report what I see.
Anyone needed more info a far as setting used any detector feel free to ask and i’ll Try an answer.
Btw my Nox 800 unit, a full factory reset done as soon as coil was on.
So so far I have have done is played with speed and iron bias setting.
Another test with pic.
That’s a big nail suspended 2 boars thickness high.
Sweeping down nail lengthways to detect nickel.
In configuration shown both gold 1and Park 2speed 5-7 gives good 2 way hit signal, 5is the shakiest though of the bunch.
Amazing how hast I can swing and hit the nickel.
Impact hit using 20khz, tone not as pure sounding as Nox though.
Deus hits using both 14.4 kHz and 28.8 kHz, gotta watch how low you set reactivty using lowest freq band.
Disc of 6.4used on Deus pitch tones, had to raid disc due to size of nail.
Some air test data.
Measured from top of coil.
Park 2 outside with single phase power lines nearby overhead. Noise cancel done.
Speed 7 iron bias 0
Clad dime approx 9”
Us nickel approx 11.5”
Speed 5 iron bias 0
Clad dime approx 10”
Us nickel approx 12”
Smaller coils performance on steel bottlecaps seems to be very similar to stock coil.
More info.
I like this coil!!!!
I did a few depth tests, not exactly scientific but will share. An almost 9”deep US nickel. Park 2 bingo. Gold 1 and even bigger BINGO. Could even get this nickel at speed 7 in both modes with advantage signal going to gold 1 mode.
A 7”deep clad dime.
Park 2 hits, need to be in speeds 4-6, speed 7 dodgy to nonexistant.
Gold 1 mode tried worse than park 2 by a good margin.
This small coil is a low conductor hound!!!
I compared Impact on both of the coins above using 4x7” elliptical coil.
Impact out of its league here.
Signals provided by Nox so much more pure sounding.
Something else to mention and I never saw this with Equinox and stock coil.
I could hit both coins using single freq ops.
The nickel I could get in 10,15,20and 40khz. Only problem was it would ID way high into upper 20s and 30s, flip to multi and Nox would ID as 10-12 on sweeps.
The 7”deep dime, would ID sing multi in the miss 220s to low 30s. Definitely telling me higher conductive target exist.
If we could devise a score card and measure every VLF detector’s attributes, it is my opinion right now just based off of what testing and small use I have done, Equinox 800and 6”coil would get a very high score. Could be the best score period. I haven’t run all detector models though.
I can I think too say, for folks living where soil minerals are even higher than mine, these folks will definitely have a ball with this coil.
I will do some more testing tomorrow.
The feel of Nox with 6”coil is nice. A person can extend rod a bit and rock and roll.
More testing.
I have commented on the use of single freq ops before here when talking about Equinox and stock coil, in particular the use of 5khz.
See this pic.
Goal to sweep across all the coins and see if Equinox will give me clue to higher conductive coin.
So does it?
It sure does.
Key is to run single freqs ops at 5khz really any of the field or park detect modes.
Conductivity levels ID use noted 20-22 with coil, GET this height as high as 6” above coins, sweep speed extremely forgiving.
I could hear using 50 tones easy.
I could hear running 5 tones with tone break for high tone at 19 extremely well.
Maybe folks don’t think this is extraordinary.
So what about Etrac and 6”exclellerstor coil? A user is SOL unless the basically brush the coins to hear clue of higher conduction (dime in this example). Btw conductive range of 25-30 witnessed on sweeps.
I highly suspect CTX would fair no better. Don’t have one currently.
Speed 5 also tested using Nox, again great clues provided to high conductive coin.
What about Impact with its 2”narrower coil 4x7”elliptical.
Using 5 kHz if you brush the coins you’ll hear the dime tonally otherwise user SOL.
Imagine how many higher conductive coins have been passed with other detectors where a nickel was masking high conductor throwing ID into la la land hence the detectorist walks thinking junk medium conductor.
Due to averaging objects conductive wise.
Folks should try this test by placing nickels close to clad dime and see what you get.
Those nickels in pic are REAL close to the dime.
Have another test to post shortly.
I should sayand this may not make much sense when I say this.
The test above although it is the dime Inwas trying to detect.
There is a very good chance a person could dig both a higher conductive coin as well as a colocated nickel.
This will become more evident when I post another test in a few minutes.
Another test. Note pic.
A clad dime and 2 pieces of sizeable foil. Parts of the foil are actually above plane of clad dime.
Again Nox using 5khz freq ops is the performer here. With very good coil height above scenario.
Etrac with 6”coil again a user must brush coil to hear the dime.
Impact IDs with coil height using 5 kHz unnormalized VDI at 33 a far cry from a high conductor ID.
Nox is smacking the dime with 23-24 ID even at coil height again with grand forgiveness with sweep speed.
I don’t want to mislead folks here. The Nox signal on dime in the above scenario as well as the previous is being affected by the lower conductor present. But just seems like it is affected less so. Granted a more compressed ID scale is likely partially responsible too. But I do think the way the Equinox is behaving here is very conducive to giving a user some real potential in junky sites to find higher conductors.
Another test.
Two ring pulls on each side of dime.
Sweeping Etrac and 6”coil FAILS, even when trying to brush the scenario with coil. Btw conductive levels noted in screen were anyway from 05 to 30 depending on sweep.
Impact with real close sweeps I can hear tiny clues of possible higher conductor lurking.
At 4” of coil height above scenario above using Imapct ID in meter is 33, again a far cry from high conductor ID wise.
Now using single freq ops of 5 kHz IDs scenario as 20-21 with an occasional 19. At 4” coil height gives very good clue of high conductive coin lurking. Again sweep speed very forgiving.
Now how about if we do a test of ring pull with beaver tail attached?
I have done.
Equinox here does not fair so well compared to the other test ran above, lousy actually when compared.
I think it is a safe bet now to say.
Folks wanting to squeeze out so:e higher conductive coins, even clad out of modern trash sites. Using 5khz single freq ops can have benefits. Just don’t forget about those bottle caps. Using 5khz they will, sing out but can we weeeded out by toggling to multi freq and notice the drop in ID. Actually in the scenarios above, if a person checks these with multi freqs after locating with 5khz the opposite will happen, meaning an overall lower ID presented in meter. Folks should use all the tools Equinox provides. Menu is easy to navigate around in when doing. Seems runninga tone break using 5 kHz around 19 is a good way to go in polluted trashy sites.
Recognize this pic.
Basically the same as one of the above expect a nail in introduced into scenario.
Does 5khz perform well here, as good as noted above?
No
Here the use of 5khz really mimicks ID wise the same as using mulit freq. So iron is the fly in the ointment so to speak.
Btw ID readings observed of 16-18 on above scenario.
Let’s introduce the third dimension here.
A pic of 2 US nickels above plane of clad dime.
Park 2 5khz single freq used.
Speed 5 fails to detect.
Speed 6 detects coil sweep speed somewhat sensitive.
Speed 7 and 8 nice signal with very forgiving swing speed.
Five tones used with 19 as tone break for highest tone.
Nickel portion audio wise detecting scale set to zero volume.
Btw mulit freq tested on scenario using Nox, no way to discern clad dime exist.
Etrac with 6” excellerator coil tried. Only time it passes if I practically brush the nickels with coil, otherwise FAIL.
Impact not tried.
Another test.
Some folks might still be thinking Etrac and other fbs or fbs2units rank supreme on higher conductors. In some instances YES but certainly not all.
Seems Nox may have advantage sometimes.
A pic.
Beaver tail only suspended above and off side of clad dime. Distance. of two 2x4s thinkness for height.
Nox using single freqs 5khz speed 7 I can hear this dime using 5 tones with tone break at 19, only with coil approaching fro the left in pic.
Repetitive hit too when approaching Fromm the right.. Definitely something I would investigate.
Etrac with 6”excelerator user is SOL, nothing even close tonally to tell me dime exist.
Another test.
See this pic.
This pic doesn’t show the test but what was used. One clad dime and 4 nickels.
Some intersting results.
First off Etrac wearing 6”excellerstor coil. Deep off fast on.
Nickle swept solo reads 13 conductive. Clad dime reads conductive # 43.
Now if I place one nickle squarely on top of dime and sweep.
Etrac conductive number reads 37- very near zincoln range.
If I add nickel on top (total of 2) etrac conductive number reads 34.
If I add a third nickel etrac’s conductive number reads 31.
Now the Equinox 800 using single freq 5khz speed 7.
Nickel solo reads 13,clad dime reads 26.
If I place one nickle on top of clad dime and sweep with Nox meter says 25.
If I add another nickle on top (total of 2) Equinox’s meter reads 24.
I I add a third nickle on top (total of 3) Equinox’s meter reads 23.
As a side note hear.
How does Equinox read if I contineunto stack nickels only (no clad dime).
Btw my tone break is at 20for high tone using 5 tones.
One nickle reads 13
Add one it reads 17
Add another it reads 19, i get no tone obviously.
If i add one more (total of for nickels in stack) meter reads 20and inget tone.
How does Nox Impact wearing elliptical small football coil react?
Running in DI99 mode 0 disc, unnormalized vdi selected, 5khz used.
Solo nickel reads 20/21
Solo clad dime reads 58
Place one nickle on top of dime meter reads 53/53
Add another nickle (2 total) meter reads 47
Add a third nickel (3 total) meter reads 44.
Just thought I would share
So some may think these tests, they don’t apply in the real world detecting.
I’ll let folks decide for themselves. I have my thoughts, and i wouldn’t do them if i thought they didn’t have some good meaning.
Note this pic.
You see the US nickel laying on the ground.
Under the paltic cap (approx) is a 5”deep clad dime I buried a few weeks ago.
The ruler is in pic to show basically the sweep angle needed to detect dime (give me good clue higher comductor exist.
Scenario swept with all detectors noted with ruler and cap removed as they contain metal.
Disclaimer here: I cannot be certian this area ia a sterile envionment metal wise besides the coins mentioned. But all detectors weere sujected to the same condirional scenaeio.
Nox 800 all park and field modes tried using multi freq. No cigar.
Use of 5khz hits the dime well with 23-25 in the meter.
Use of 10khz hits too, but a bit more dodgy than 5khz with ID a few points lower. The other freqs a no go for good ID, meaning they son’t give me clue of higher conductor.
Etrac wearing 6” excellerator coil. Fast on deep off, i get little small spirts occassionally of somewhat higher tone on controlled sweeps showing conductice numbers in the 30s with highest noted 35, most times 32/33 displayed.
Nokta Impact with small football coil, it will give me clue of higher conductor using 5khz as long I keep the toe of coil off of the nickel. It reads 61/62 most sweeps which is a bit high ID wise for clad dime ( air test 58).
Another test.
Real simple one.
Etrac and Equinox compared. Both wearing 6”coils.
Nail is around 2.25” long.
You see the clad dime.
Sweeping over nail and coin, try to get a strike nonferrous tone wise.
Etrac will give clue of actual higher conductive coin, with very controlled sweeps.
Special note here. You run run ferrous disc too high (black in the screen) you can miss even with the best of swings over this dime. Setting ferrous to the lines of 25-27 yielded best signal. Not near as good a signal though as the mighty Nox.
Equinox only park 2 detect mode tested.
Single freq ops, user more or less SOL, occassionally a one way lower tone.
Mulit freq here folks isnwhere the action is. Equinox sounds off strongly on dime at sppeds 6 and 7. Speed 5 dodgy and disn’t try speed 8.
Mulit freq acts a lot like Nail not even there.
Id of 18-22 noted in meter.
Another test similar to the above test yet more difficult.
With factory default disc in each of the following detect modes tested, detector quiet when nails without dime are swept.
Park 2 multi freq gives good 2way hits speeds 6 and 7, 5 is sweep critical, didn’t try speed 8.
Single freq ops.
5khz a no go.
All the other single freqs would only yield one way hit. If I slowed way down sweep wise sometimes 40 khz would yield 2 way signal.
Mulit freq use provided 17-21 in meter.
Iron bias set to 0 in all testing on the above.
Using multi freq, chedked park 1and 2 as well as Field 1 and 2.
All run in 50 tones.
Park 1 the least performer.
The other 3 detect modes did very well.
If I had to pick the best one it would be park 2.
So how about Etrac and 6”coil.
It will give me clues of dime existence.
Key is keep ferrous down to 25-27, you bump ferrous up to 23, spells trouble for detection.
Nokta Impact wearing small football coil.
Passes very well here.
Actually it imo does the best here as far as tonal presenation and ID on dime (combined). All freqs checked all passed.
Equinox gives best tonal presentation overall.
But ID not as accurate.
Remember Impact’s coil here is 2” narrower.
Let’s see how the Nox and small coil do in airtest on these 2 rings.
One is bigger man’s ring 14k.
The other a woman’s ring 10k.
Park 2 tested speed 6.
Noise cancel done.
Sens at 24
Rings were swept with opening of ring facing coil, same plane.
Big ring signaled to distance of 14” approx.
Woman’s ring signaled to a distance of 11.5” approx
Sens at level 20.
Bigger ring signaled to approx 12”
Smaller ring signaled to approx 10”
First test down the barrel of nail using clad dime. Ruler in pic to show nail size and orientation.
Nox in gold 1 passes test speeds 5-8, iron bias 0-1.
Park 2 gives trailing tone off the left.

Nail is around 2.25” long.
You see the clad dime.
Sweeping over nail and coin, try to get a strike nonferrous tone wise.
Etrac will give clue of actual higher conductive coin, with very controlled sweeps.
Special note here. You run run ferrous disc too high (black in the screen) you can miss even with the best of swings over this dime. Setting ferrous to the lines of 25-27 yielded best signal. Not near as good a signal though as the mighty Nox.
Equinox only park 2 detect mode tested.
Single freq ops, user more or less SOL, occassionally a one way lower tone.
Mulit freq here folks isnwhere the action is. Equinox sounds off strongly on dime at sppeds 6 and 7. Speed 5 dodgy and disn’t try speed 8.
Mulit freq acts a lot like Nail not even there.
Id of 18-22 noted in meter.
Another test similar to the above test yet more difficult.
With factory default disc in each of the following detect modes tested, detector quiet when nails without dime are swept.
Park 2 multi freq gives good 2way hits speeds 6 and 7, 5 is sweep critical, didn’t try speed 8.
Single freq ops.
5khz a no go.
All the other single freqs would only yield one way hit. If I slowed way down sweep wise sometimes 40 khz would yield 2 way signal.
Mulit freq use provided 17-21 in meter.
Iron bias set to 0 in all testing on the above.
Using multi freq, chedked park 1and 2 as well as Field 1 and 2.
All run in 50 tones.
Park 1 the least performer.
The other 3 detect modes did very well.
If I had to pick the best one it would be park 2.
So how about Etrac and 6”coil.
It will give me clues of dime existence.
Key is keep ferrous down to 25-27, you bump ferrous up to 23, spells trouble for detection.
Nokta Impact wearing small football coil.
Passes very well here.
Actually it imo does the best here as far as tonal presenation and ID on dime (combined). All freqs checked all passed.
Equinox gives best tonal presentation overall.
But ID not as accurate.
Remember Impact’s coil here is 2” narrower.
Let’s see how the Nox and small coil do in airtest on these 2 rings.
One is bigger man’s ring 14k.
The other a woman’s ring 10k.
Park 2 tested speed 6.
Noise cancel done.
Sens at 24
Rings were swept with opening of ring facing coil, same plane.
Big ring signaled to distance of 14” approx.
Woman’s ring signaled to a distance of 11.5” approx
Sens at level 20.
Bigger ring signaled to approx 12”
Smaller ring signaled to approx 10”
