If anyone can enlighten me that has had success with either, I would love to hear your views. What makes the II different from a standard Excal? Is there any improvements in depth? Is it better at discriminating targets? Has the battery life been improved? Also has anyone used it hipped mounted with a straight shaft (either unit), and did you encounter any malfunctions? I've used the Garrett Infinium which is an excellent machine, but can deafin your senses if your in any populated or trashy areas. So I've been looking in another direction (Tesoros Sandshark, Whites PI dual). Although it's not a Pulse Inductive unit I still wanted to get your opinions. Thanks, RickyD
