internet search engines are your friend...
I would have said my saw was a sliding miter saw, but after searching it seems the dual part means that you can tip it sideways and well as rotating it. So it is a dual bevel sliding compound miter saw.
Mine is a Bosh 5412. I like it and it does everything I have asked while redoing the woodwork in our last house. It is about ten years old, so YMMV with a new saw.
Oh, Hi from East Central Illinois.
