Yes....Iron bias..-minelab...=...bottle cap reject..-whites...=silencer..-xp deus...=...mask iron-rutus....

an excellent real review, thanks..., and I agree with the multitone-tone id on Spectra v3 is a bit pesado ....

Equinox can use 1-4 wireles audio ouputs at once,-in 50 tone, so it will not be a problem to use some spectral sound analyzer in a mobile phone ... even though a good sound signal is being heard ... and then VDI...

sometimes we do it ... Spectra 12x10 and backpack Golden mask coin killer -9 "spider with sennheiser rs 160 wireless headphones...

In EMI -for elimination EMI - try to change as follow : 1.auto-or manual Noise cancel... 2.recovery speed to low.-for better signal ratio ground--EMI,... 3.tone volume-audio gain-it s max.25....,go- to low, or-minimum...minor gain audio-minor gain falsing signals, ... 4. and increase iron bias ....minor signal falsing....5. increase sensitivity to maximum - the stable...non false signals......... For false signals from the ground,.. apply only steps 3. Tone Volume-very important,.step..4,..5...and step 2.- recovery speed filter to high recovery speed filter...

equinox transmits in 5-80khz and accepts 5-40khz, and over 40khz all filters .. under the patent ... Tx motor -3wave. but the basic sensitivity of the multifrequency to the objects will be much more like the Spectra ..- there is quite similar to 1f -7.5 khz ....beach program is a question ... does not it work in bost?

In some extent, the extent of iron bias can be considered as still effective ... the aim is to remove false signals from the iron ... and it is sufficiently separating properties

that's true,and also the standard coil-size is not too sensitive to the tiny golden chain ...

Iron bias and recovery speed with adjustable items -DIFFERENT PROGRAM SETTINGS IN THE MANUALS , each with their case according to the situation .,and ground...-no problem...

Low Iron Bias is not decrease a short coinage signal in long iron, or a nail type --- o --- o --- o --- o ---, the large iron bias is partially or fully signal decrease from the coin. it is not so much a problem with a short signal of iron, nail, and coins in terms of type : I o I o l o l o I . For a high recovery rate - very short iron and coin signals, use of low iron bias will not the decrease signal of coin in iron. Iron bias also suppresses the short signs of mineralization of the ground, EMI, but also deep and weak signals of coins in the ground.

In Whites Spectra V3 bottle cap Off/ and bottle cap On / seting1 its big diference for unmask coin in iron...depend on location iron and coin, -produces better "full range" signal iD and audio ouput...better-bledy audio....In Argo and Optima i use minor "mask"-iron bias 2-3.max for better unmask...

In 2 tone, 5 tone ,50 tone,...tone ID..

Iron bias - it is filter -short signals audio -for unmask ,type- silencer-xp bottle cap reject- whites.....in minor setting Iron Bias + optimum recovery speed- it is unmask better...in iron sities.... Great "vizual-audio" test for optimum setting iron Bias its :7 X small -medium coin and 8 X-4" nails about in Line...,..2 .test coin beside horseshoe, 3.test nailboard test..

Mike your settings in Test for Spectra for 6x4 shooter?,Rx gain, Ds , recovery speed,and ground filter?, thanks...
