This simplex has only been in the field one time. Still has about one year an three months on the warrenty. has all the updates except the last one. I bought this one without wireless headphones. so it will be the detector only. Reason for selling is I had a multi kruizer when I bought the simplex. I needed to sell one or the other, so I decided to sell the simplex. very good machine, but I have to many detectors. 220.00 shipped.
