Why? As a newbie I had the it really helped me to learn the sounds of Iron in a bigger iron part.
When you have a bigger lump of iron the target ID raises and sounds relatively good.
The Rutus really helps me to identify the target as iron. It shows a sweeped line in the screen. When it's brass copper etc the line is vertical.
What really wonders me.... Why only the Polish and Russian detectors have this?
I know the Deus has something similar.
Why is this not standard on each detector? I can't imagine a next detector who hasn't this feature.
It is an excellent tool.
The Whites Signagraph showed both ferrous and conductivity (intensity), not sure if the Rutus is the same though?
