The Threshold feature enables you to change 
the amplitude of continuous background noise 
that helps you pick up on faint signals from 
potential targets. This is especially useful for 
identifying items that might otherwise go 
unnoticed. The Threshold Level can be 
adjusted on a scale from 0 to 25, allowing you 
to customize the amplitude of this background 
sound.  
While most modes have a default Threshold 
Level of 0, meaning it's turned off, the Gold 
Mode starts with a default level of 10 to aid in 
the detection of small gold pieces. 
How to adjust Threshold.  
When you spot the Threshold setting, 
click ▲ or ▼ buttons to adjust the level.
The Ferrous Bias feature is a valuable tool that 
allows you to accurately sort ferrous from non-
ferrous targets. By adjusting the Iron Bias 
settings, you can fine-tune your detector's 
ability to identify large or complex iron objects, 
such as rusty nails or bottle caps, and easily 
reject them. This feature is especially useful 
when you're operating in HyperQ frequency. 
The benefits of this feature: 
Firstly, it gives you the power to discriminate 
against unwanted ferrous targets, saving you 
the effort and disappointment of digging up 
trash. Secondly, it allows for a more focused 
and efficient hunt, tailoring your detector's 
capabilities to the types of items you're most 
interested in. Lastly, the setting enhances your 
ability to navigate challenging terrains and 
conditions, adapting to different levels of iron 
contamination in the soil.  
The Iron Bias feature and FeScale function work 
hand-in-hand to optimize your metal detecting 
experience. Iron Bias allows you to fine-tune 
ferrous target identification, while FeScale 
enhances precision by visually displaying the 
ferrous to non-ferrous ratio. Together, they offer 
a comprehensive approach to avoiding 
unwanted digs and focusing on valuable finds.
