 The transmitting frequencies of 5khz and 40khz are used to create a TX square wave ...   ... The transmitted signals change according to the type of program..

Equinox-multifrequency-do not take 5 frequencies only in terms of sensitivity and range, it is the exact iD ... computation, and removal of ground signal - in depth and mineralization, salted water. , it divides the equinox from the normal VLF .. Clearly the possibilities of improvement here would be-I would envision the expanded ID, + 10  extra numeric ID  in  for low conductive objects in type 2 programs and gold programs...and it's perfect...Of course the multifrequency has a precise and strong impact - even in a small weight category...-test sniper coils...-4 bar tekG2 ,mineralizaded ground...

This is what one can do One frequency-every frequency has its own advantages and disadvantages, while Multifrequency .. can use these benefits and suppress the inconveniences. The next multifrequency is much more information and data about the signal that is to be processed into the detector .. Even a single-frequency detector can be very good if it is properly designed and set on a given field ...and the same type  of searching...
 

...Idea is good...., glas- display,-headset - detector, application, ..."Piochon"   not .. good idea... better idea - ist have pinpointer with TID and gps tracking and writing good finds.... But it's not XP info...

Equinox is not in any case castrated Spectra, it's a high-power multifrequency  metal detector ...

Deus V6 ?....yes, it's false information ...

It's not necessarily, for example, on sensitivity 20, on the contrary 15X12 "coil works at me in a wide range of Recovery speed 1-7  good signal- whit ID,,and best signal - recovery speed 4- better... than 11" standard coil  at Sensitivity 21  -It works well on the recovery speed range 1 -... 4   whitID,max5 .. to recovery6,7,8 is weak signal - at very deep targets - coins 50eurocent to 37-38 cm= 15".. in the ground .. picture-rate mineralization ground..in Test...
 

Yes, setting recovery speed to impact on Ground balance the  Equinox, keep in mind that recovery speed is more or less perfect electronic replacement of coil sizes .. -to a certain extent...

 Spectra V8...The effective frequency range of the multifrequency is about 1: 8, so I need 2core sequential multifrequency power transmitting unit with 2x range working together, 1.5khz-12khz and 12khz-96khz.., and user programs with different use of these frequencies ..resistente EMI ... Tx Bost...Display such as the Spectra and the two-digit TID -like CTX- which uses data from 2 core...Waterproof...weight 1.2-1.4 kg .. the picture is the TX wave for Spectra V3 -even with this detector, there is a great possibility of improvement...

...Today in deep tests 3 Equinox coils on Park 2 I found that I changed very strongly the values of phases at Ground balance ,,, - it was shown to happen when changing recovery speed .., so I checked it-tested: program Park2, sens 20: ..recovery speed1 -number Gb-47, ..recovery speed4 .. number Gb-37, ..recovery speed 6 ..- number Gb-32, ..recovery speed 8.-number Gb-22 ... So I recommend to change the recovery speed,.. make  a new Ground balance...
 

Yes,.... the 15X12 "equinox coil is deeper than the 11" standard coil, it's like more + 2 sensibility, and it's most visible at high recovery speeds ... where the 11 "coil does not even increase the sensitivity ...Today I tested all 3 Equinox coils on the Equinox 800, plus other coils on the Whites Spectra V3 ..

Praying Whites to give us our best innovated detector ...Spectra V4,Spectra V5...

..that is a crystalline pyrite from Navajun-Spain-from times when I did not have a metal detector ...,also nice times...only hammers and mowers..

I think the automatic noise canceling could take 2x-3x longer, better would eliminate the non-linear EMI ..

One of the possibilities of comparing the current and the new firmware is to locate 10-20 suspected signals in the terrain, and then verify them on another firmware ... at the same time...

yes, try also to shut down Allmetal, it will also help you, rumbling when you are under electrical lines...

If you ever find yourself happy with automatic noise cancel, try also manual noise cancellation to remove Emi, sometimes also help if at noise cancel hold the coil about 10-15cm to the ground ... What helps ... is the low recovery speed...As for the elimination of EMI in the Whites Spectra V3, use a smaller coil but still the depth of the coil-Mars sniper 6x10 ", 5hz band filter, Txbost ON, and Modulation  audio - to 1- max2 ...

Yes,, Garrett ace 400i is a good detector, compared to 350-plus numeric ID,... and Iron Audio...-better separation, and identification of iron, and my observations are sufficiently sensitive and deep ...

Thank you for commenting, and an outstanding look at the work of the 3F multi-frequency  Whites Spectra - Nailed....First of all, to say that the test video does not come from me-is from scannerguy1968... but it shows the work Whites Spectra V3i on targets in the terrain, using 3F signal analysis on the targets - which I also use - 3f pinpoint,3f spectragraf and 3f signagraf - especially in the weak, or mixed signals - which do not provide a stable ID, but in the audio signal they give partial tones to non-ferrous metals....in this case the use of Spectragraf shows the prevalence of the signal on non-ferrous metal, so I dig it ...

White's V3i Information page

We will see what Minelab is doing in the right direction of the coils .. Many Equinox users - many demands on the size of the coil - other manufacturers can also enter the market ... the multifrequency coils ... now on the test this  multifrequenci coil for the Whites Spectra V3: 
 

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...
