If you have the newest rev 6.1 QKLX5M4 Can anyone tell me what there serial number is. It's on the bottom of the detector. I think its on the box to. I can not find one at my local Best buy . I really would like to have the newest rev 6.1. A tech at passport told me it's better than the older rev and it will false less.
This could help us all out when looking for the newest x50.
Most of the serial numbers at Best buy start with 027 they are not the rev 6.1's.
