Probe+ sensors 3D can detect gaps up to 40 meters and scans up to 25 meters. Completely revised and updated, improved microprocessor and faster Rover C II with real-time communication between computers.
Compared to the basic version, the Rover C II provides the ability to detect gaps up to 40 meters using the 4 sensors supplied. It not only detects metals underground,
also underground chambers, tunnels and cavities
You can also detect . functions:

magnetometer noise
Ground Scan scanning to detect abnormal metals and up to 18 meters
Geo-electric scanning to detect gaps up to 40 meters deep
With Super Sensor
between noble or ferrous metals
3D in scan recognition higher resolution scanning probe and Super Sensor for displaying lines on your computer. The new ROVER C II Edition includes the following new features:
probe light (button) backlit display
tip
, highly mineralized soil
data transmission rate
greater stability and improved electronics, by neutralization doubled simple and intuitive control of menu navigation
Researching new battery pack with long-term autonomy
wireless stereo headphones
New waterproof carrying case, shockproof, handles and wheels
weights and very small size
