1 review for Carlson BRx7 Base Rover

  1. Mike

    “The site was about 2/3 wooded, hardwoods and areas of pines/cedars. After localizing on control, we were off to the races. The receivers navigated us right to the irons and we were literally hitting them by hundredths of a foot. We were able to maintain a fixed position with the rover in the woods, including the pines and cedars. Amazing!
