I have been hunting with the se & f75 for about a yr. and before I used a cz. I not saying that the se & f75 are not good . I use little coil on all of them and the old cz goes deeper and has a faster recovery . The f75's recovery is very close to the cz and bought ID work good. The SE ID doesn't work good in trash at all. I think if fisher would take a cz and put the ID meter that is on the f75 they would have the best detector going.
