[ECGBaritoneMastr]

Hey. I was looking into the leather case with a swivel clip for my Radio Shack PRO-95 scanner. (http://www.scannermaster.com/ProductDetails.asp?ProductCode=01-580816) Okay st upid question. When i have the whole assembly clipped onto my belt, will it fall off when i'm running? Will the part that hold the scanner sway back and forth when I run? Yea....just wondering and thanks.
