I really like having the pinpointer paired with the detector. Most of the time, it works great. Periodically, the pairing doesn't work. Sometimes, simply turning it off and back on does the trick yet at other times, it takes several tries. Today, I had to un-pair it and then re-pair it to get it to work. Several times afterwards, I had to turn it off and back on a couple of times to get it to work. Most of the time it works great but sucks when it doesn't. I was using Program 2 Sensitive on the Deus II.
