I went out tonight on my bike to sit with my LEO friend while he ran traffic with his Sgt. His Sgt. looks over at my 8500, point his Stalker handheld at my 8500 and quick triggered it. My 8500 was silent. He then held down the trigger and it alerted to K for a second and then went into full Ka alert. Then another quick trigger burst.. it was silent. He looked at me and kinda laughed. (ive met the Sgt. before & he knows Im into radar) I thought ive read somehwere that the Escort can miss a quick trigger. After his Sgt left, we went out on a ride.. We stopped at a light and my friend aimed his K band gun at my detector and it went off instantly. I asked him to quick trigger it like his Sgt. did. It alerted instantly on K band. Does my 8500 need to be looked at, or is this normal for the 8500. Im not sure of what revision I have. I think i bought it in mid 2001.
