One of my areas I pound I carefully gridded and hit it from three directions with my mxt all pro. I made sure I overlapped by 50% and carefully hunted an area. After many months of working out of town I finally decided to take my v3i back over what ive hunted with my mxt. (I no longer have the mxt). Im happy to report that the mxt swept the area really clean. I only found 1 dimetthati had missed.
