The Tone Space setting, which adjusts the end 
positions of each tone region, is a powerful tool 
for fine-tuning your metal detecting experience. 
This setting is especially useful for dictating when 
and how different types of materials trigger 
specific audio responses. For example, you can 
manually adjust the tone spaces to make 'coke,' 
a common but undesirable non-ferrous target 
with a typical Target ID of 1, fall into the ferrous 
range. By doing so, it would then trigger a 
ferrous audio response, helping you avoid 
digging up this nuisance item.  
However, a word of caution: altering the tone 
spaces can also mean that some low-
conductive, potentially valuable targets may give 
off the same audio cue as less desirable ferrous 
targets. This is something to keep in mind based 
on what you're hoping to find. 
Another advantage of manipulating tone spaces 
is the ability to make more distinct separations 
between targets of varying conductivity levels. By 
finely tuning these spaces, you're essentially 
customizing your detector to be more attuned to 
the types of materials you're most interested in, 
thereby making your hunting more efficient and 
rewarding. 
How to adjust Tone Space.  
When you spot the Tone Space setting, click the 
upper ▪  repeatedly to access the specific 
region you want to adjust.  
Then click ▲ or ▼ buttons to adjust the 
breaking point. Hold for fast movement. 
The bars on the standby interface will change 
accordingly. 
Tone Numbers.The ability to adjust tone 
numbers in a metal detector is highly influenced 
by personal preference and the specific goals of 
your treasure hunt. For example, you can set the 
detector to operate in '2-tone,' '5-tone,' or even 
in '99-tone' infinity mode, where almost each 
metal type is designated its own unique audio 
cue. 
With the ability to fine-tune the audio responses 
based on what you're most interested in finding, 
you can essentially make the metal detector an 
extension of your own senses. This 
personalization makes your searches more 
efficient, reduces the amount of unwanted items 
you dig up, and overall enhances the joy and 
effectiveness of your metal-detecting adventures. 
The tone numbers you choose directly change 
the tone spaces quantity.
