Just came to mind that this time of year may not have been the best time to have detector shipped. We are experiencing very frigged temps here in the mid-west. Tomorrow's wind chill is -50 to -60. Reg temp around -30 for low. I am not sure how this will affect lithium batteries in Nox package. Not sure when to expect delivery, because tracking has not available yet. Dealer was talking about Thursday delivery, but I don't see that happening since it has yet to be picked up by ups. Kinda hoping for a lengthier delivery now. Any one know for sure how cold affects them?
