I want to make a metal detector
But I'm experiencing a little information about my Metal
I am an electronics student and I'm graduating soon Unfortunately my poor English.
Friends want to help me to choose a career in this field circuit with the features I want.
My favorite features:
1)Digging deep for at least 2 meters metal 1 m × 1 m,and work in a rocky environment

2)Navigation and display of depth, and sensitivity to precious metals such as gold

With this features you can introduce metal detectors.
Thank you so much
