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

Potřebuji tento test znovu zkontrolovat, abych zjistil, nakolik byla nastavena citlivost.

Ok smysl 70 a ve 3 tón (rychlé) snad 2 tón by měl větší zisk / citlivost na řetězy?

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...
