CrossOver is a general-purpose series of GPR-systems, in three different housings and with 6 separate frequencies in the range 70- to 800MHz. It is designed for the professional-geo community. It may be pulled or pushed in dedicated carts, by hand or by means of vehicles, at any speeds. Each system comes as a true-dual frequency antenna with inbuilt control electronics and GPS-modules. The systems are controlled via Android-pads over a wireless link. It is based on real-time-technology which gives excellent depth penetration and bandwidth. Low power consumption gives 7 hours operational time, on one battery.
