Small 5 "and 3.5x6.5" coils can be closed with epoxy and keep low weight ... Coils 5-6 "x9X10" and 6X8 "require different design to maintain low weight. Equinox is also 6 "the coil very deep detector .., so how to close the coil for gold prospecting I would see something like 4.5-5"x8-9 "...The 6X10 mars sniper coil is  sensitive and very deep coil ...  to its size... reach similar to 6X8 -sef coil ...

Better 70-% use the 15X12 coil on the detector,..how to let the big and heavy coil fall in the cabinet.Important is that 15X12" is as sensitive as 11"standart coil..and it has more depth... 

...the carbon rod can lose weight by 100-130 grams - on the side of the coil it hangs on the detector's construction, -   1 long bar is used. assuming one is the length of the rod instead of the middle and the lower rod. ..- the next thing is the battery weight- the use of a Li-ion battery can lose weight by 150 grams - and if the battery is built... even more. 3-piece  carbon telescopic shaft ..- is optimum ..
..I believe the Whites are working on it...

I do not have to play video - because I have it at home from my observation is deeper. clearly, you can wait for some of the test videos ...
 

I think that for many detectors the 15x 12 "coil will work, most of the time as the main coil... That coil  i have the sensitivity and reach of very tiny objects, but it also has a lot of reach for coins and medium and large objects. Is a control comparison of 15x12 "and 11" coils,  in program Park1 and Park2 on sensitivity 20 and recovery speeds 4:in a moment I will publish the results of the airtest...

Personally,  weighing the Equinox even on a 15x12 large coil as well ... ... I have compared a standard 11 " coil and big 15x12" coil - at 50 eurocents buried at 38cm in the ground. Test Field is uphil - so detecting that coin from different directions its more difficult ... here the standard 11 "coil had a problem with the detections - it did not give any good signals, or repeated, but .. one-sided signal .., so a large coil gave good signal from ID from all directions .. , Tested on programs: Park1, Park2, Field1, Field2 ... In my opinion, Park2 and Park1  pronouced beter signal  in sensitivity 23-24, than Field 2 and Field 1 at the same sensitivity. In each program I tested the sensitivity and range of the coil on 3 small items in the ground: golden O- segment 0.05 gram of gravel on 10cm in the ground.13.5mm denar drained to 23cm in the ground, and 13mm silver earrings buried on 20cm .. programs Park2 and Field2 gave signal and ID to all 3 small objects on the sensibility 22, -its the excellent sensitivity and the range for big coil.....  The 11" standard coil which takes it in sensitivity from 21 ... Park1, and Field1 no pronounced signal at golden 0.05 grams of the O-segment can not be seen sometimes in some situations again ... all of the first tests ..the cross indicates the position of 50 eurocent, 3 plastic collars position 3 of small objects in the ground...

...in this test I also tested the coins, small and medium size  coin,,....50eurocent at a depth of 38cm in the ground, and 1 Polish grosz-15mm -1.65gram coin-at a depth of 29cm.in the ground. and the big coil detects these coins with a good signal, tomorrow it compares to 15x12" coil and 11"  standart coil on these coins...
 

It's lead ... And I increase the sensitivity from 20 to 22 - 15x12 "coils - Is similar or exceed the range of 11" standard coil ... Tests in terrain at 0.05 gram gold O - segment at a depth of 10 cm in the ground I show it - when raising sensitivity 21-22 to -11 "standard coil-with sensitivity 23,24..to 15X12 large coil..this coil is sensitive ..., works well on high sensitivity...tested in programs  Park 2,recovery speed 4-5 is optimal-in test..,  
 

short-coil  airtest for small things, program Park2- sensitivity 20, recovery speed -4 ...,weight in grams,diameter items in milimeters, distanse in centimeters..

11 "standard coil-506 grams, .. 15X12" coil-660 grams, 6 "coil -303 grams .. -15v12 coil-is of its size, very light., that sounds very solid .. I have measured the weight of the coils...now test for very tiny items...

The first control airtests indicate that the 15x12 coil is equally sensitive to small items like gold earrings, or small 13mm -0.50 gram silver coin Denar ... the middle, and the big coins are  deeper - programs Park1, Park2 for recovery speed 2 and 4  and sensitivity 20... The impression of the big coil has more than the same reach of these two recovery speeds 2 and 4-as compared to the standard 11 "spools there were more differences .. tomorrow I will make a test for the smallest items ... and then tests in the ground...
 

I have a first look at the 15x12 Equinox coil. the exact size of the coil without the cover is 30.7cm x 38cm, the weight of the coil with the coil cover and the cable is equal to 660 grams .., mounted on the shafte golden mask is light-so it's okay ...
 

I like to see the 13 "-13.5" coil....somewhere I read that for 50eurocent coins it gives 5cm more, and big coins is more ....I'm curious.,  know how the big coil will detect all coin sizes ...The weight of this 15x12 coil  should be about 650 grams ...- it's a light coil...

Maybe I'm lucky, -the" big" coil on the Equinox is on my way home to me, when it's a weekend so I get it on Monday 15,

.For the 2D nailboard test, the size of the coil has a significant effect on the results ... 11 "I have bad results in the 2D nailbord test" Coils 9 ", and I have less than good results in this test ... In my the 3D-deep separation test, coils Under 9" they have bad results and on the other hand coils 9" and more have good and excellent results in the 3D test .., - here is also the height of the coil above the nails, most of the detectors work well from 0-15,20 cm above the nails, except is Tecnetics G2- 13 "ultimate - the 0-20cm does not produce a positive signal signal, it starts to pass such a 3D test and at a height of 20-25cm above the nails with a very high separation is good for detection in winter ... when it's snow-...Detectors in my 2D naiboard test and 3D test: Whites SpectraV3 -4x6" ,6x9"eclipse,8x6 "sef, 10"dd whites,12x10"sef,6x10" mars sniper coil,,...Teknetics G2 - 3.5x 6.5" nel snake ,11"dd ,13"ultimate coil,..Golden mask coin killer 15khz-5"spider,9"spider coil,.... Rutus Optima- V.2-16 khz DD23CM, DD29cm coil, rutus Argo V.3 6.6khz..- DD29 cm coil,....                                                            If you are testing the detectors in the nailbord test, you will notice that almost all detectors have the problem of passing 4th in coin position number 2 ... detectors with fast reset recovery delay do not keep, Whites Spectra V3 with recovery delay setting 45 or more it goes very all right.

I have already ordered 15X12 "coil .. should be available from 15.10.2018 .., price is reasonable ... 265,.. euro.

I will call there and ask ...

Yes you can, the price is about 15 Euros....

Carl, .. I read, ...so is the development of a multi-project ...We believe that a time frame is needed for such a product development...

If the multifrequency is sufficient to shift the work channels, it can well eliminate the EMI, and if it's not so good enough to use a smaller coil, which is mostly EMI-resistant, the other option is to use a program that is less disturbed, and and then degrade sensitivity ...
 

Today I am in a test to eliminate Iron .. also came  with Equinox 800-6 "coil several 0.17 pellets with ID 3 and one 0.22 with ID 4-5 ...

The Iron Bias setting also influences: 1.Of the detector frequency used, or the multifactor program weights, 2. the set recovery speed ...,. 3 Detector Discrimination Used. and also 4.
  detector sensitivity adjustment ... Now you can select -A: Do you want to increase the separation and unmasking of the detector in the iron? .. or B-do you want to discern iron-plated bottle cap caps? ... If you want to maximize the separation-A give the frequency, the multifrequency program type Park 2, the high recovery speed, the  less or no dyscrimination, and  less the sensitivity of the detector ... If you want to determine what is a ferrous waste- B, use a low frequency, a low power, low-frequency Beach 2 program to scale!, increase the iron bias to the maximum !,recovery speed high 7-8-!-its less sensible for, tini,or plated metal.. , increase the discrimination setting- !, and decrease the sensitivity...
 

...Today I was passed the Equinox 6 "coil on my Carbon Telescopic shaft, on my" clean terrain, and I started  Test 1-"determination of Iron" to compare the work of the Park 2 main program and the iron control of the Beach 2 program stored in the User profile .. at high sensitivity 23 .. I compared the signals with ID 15-17 before digging with a fine iron tone, which, after checking in the Beach 2 program, clearly pointed to id -6 and the pure iron tone ... which after the excavations turned out to be old nails ... Another comparison Test2 -"identifikation nonferous" was found in the Park 2 signal program with positive IDs with a bit of iron signal that would be in line with the Beach2 ID and then dig it ... I dug a few pieces of colored metal .. so I have the impression of reliably  getting enough of this test. .My program Park2 settings: sensibility 23, allmetal,recovery speed 7,iron bias 0-1,. For control Iron-  In user profile: program Beach 2,sensibility 23, allmetal ,recovery speed 8, and iron Bias 9.. It's during the test 1. - the nails in the ground - in Park 2 I have been trying to reduce the sensitivity from 23 to 15 to lower to get some better signal on iron and less signal for colored metal .. - but it was also not ideal. Continue in 2 tests to see from program Beach 2 did not have the problem to show a good ID for such a small shot-pelet in the ground ..Photo on left side test1- determination of iron-is pulled out of iron ... on the right side Test 2 on the truth of identification of non-ferrous metal ...3  pellets and piece of metal ..

Another step forward - how to use the Signal probe function to repair a coil that is out of signal tolerance ... I degraded the signal value below half the value and removed the overload ...
