Just started using my R10 in my garage. After a couple of sessions I noticed that my club distances (comparing use on the range vs. garage) are about 10 - 15 yards less than average. I read last night that the concrete floor could be causing interference and throwing off the radar readings. I understand that the garage floor should be covered with something to possible prevent this interference. However, how wide of the space between the R10 and my hitting mat do I need to cover; 2ft, 4ft, as much as possible?
Thanks for the feedback,
Jerad
