Thanks to the mono 45cm coil or mono kite coil you have with M1, you have a deep search detector that can completely eradicate the mineral by balancing the soil. This allows you to detect metal from the depth you cannot imagine. Not affected by the mineral. With the Gradiometer .M1, you can detect non-natural, man-made structures under the ground. This allows you to display substructure of tombs, tunnels, chambers, etc. in 2D or 3D from the M1 screen or from the tablet or phone screen. You can make detailed analysis thanks to our integrated Voxler program.
