The Schlß makes a stable impression and is in focus by simply attaching to the brake disc. The signal which is indicating loudly, to be exact, it is almost louder than the actual alarm. After it is brought into focus, I have tried to give the alarm, because you have to shake already properly. Best draufschlagen. I returned it and 2 more Detectos 7000 tried in the store. None !! How do you say my Detecto Granite is suitable with position sensor in this case. Here there is only 1 star because that's what it takes deficient to my taste. I fear the Detecto 7000 RS2 can carry away the motorcycle without a ALARN is triggered.
