They do not have bobbin detection but they do have top thread break detection. The bobbins run tighter and the top thread tension is really no big deal. I don't use my 4 head machines any more, but I do still use the single heads every now and again, even with 8 amayas. I have a couple of items that run easier on the old machines.
