I had ver 7 on my Deus II and did not like it much. I decided to down grade back to ver6. All went well and hunted with it last evening for a couple hours and it worked great. This morning, I went to put it on the charger, and no response to the charger, and the remote would not turn on. It is totally dead. My dealer had no idea why it did that, and recommended the remote be sent to the repair shop in Southborough, Ma. So I will be without my Deus II for a week or so. Good thing I have 12 other detectors, including a D1. to use. It is disappointing though.
