Tone Break adjustments


Well-known member
The adjustment of the first tone break has a significant impact on the separation/unmasking of Non Ferrous targets co located in nails/small iron. The Factory default of 10-11 only gives fair performance. Dropping the first TB back to 6,7 or 8 greatly improves this performance. Most common nails TID around 4,5 or 6.

You can also use the Tone Break feature to have most common Pulltab trash isolated to one tone bin that is given an ugly sounding tone. Use 6 Tone or 4 Tone to make an effective 5tone or 3 tone pattern. This is an alternative/addition to using the C Disc Notch feature.

When you say “common nails” are you referring to the round shank round head type? I get into a fair amount of square nails and more recently big ol horseshoe nails. They, for me, sound off high numbers (the larger ones) usually just slightly above quarters.

I had in mind the nails common on my typical relic/old home site permissions. These consist mainly of late 19th-early 20th century wire nails & somewhat older cut nails. Almost always well rusted. The only true hand forged Square nails I have dug are larger spikes. The forged iron reacts differently than machine made cut nails or Cast iron pieces. I like finding it. The Legend handles them all better, with less falsing than any other detector I have run. Bigger iron will false, but if not too deep the Ferro Check & mixed tones will call it out. Deep large iron can still fool you till you start digging it. Same with small thin wire/nails if badly oxidized.
