This antenna is the compromise between the high resolution of the GCB-400 and the deep penetration of the GCB-200. It will give the best of both worlds with small sacrifices to it. This is the perfect choice for companies that don't have the opportunity to make a big initial investment, but still have a wide variety of jobs to do. In many cases this antenna will suffice for all your applications in utility detection surveys. As with all other antennas manufactured by Geoscanners AB this antenna is fully compatible with all GSSI control units.
