Our sensors were shielded and worked perfectly on our practice field. At the different regionals I was at I used the IR tester that was at each event to prove that the field beacons worked. By turning the sensor around you could see were the different beams were coming from. I could get readings from both sides when facing away from the beacons. There were times were I could pick up the beacon behind me but not the one in front. The people testing with me were slightly baffled so I am not sure on how they did their initial tests.
