Hi, I am so sorry to bother anyone with this. I owned a Garrett 500 pulse for 25 yrs and I just bought a new Minelab Excalibur 1000. Of course the reactions to metals are different, and I am lost. I would like to know an easy set up for the knobs to start with, and I'll salt my backyard to figure out what I am hearing. I think so far, the twang noise is iron when going over something, and the sharper noise is a good target. Any comments, or am I screwing this up from my Garrett. By the way, I could tell with the Garrett what kind of metal and how large after so long of using it. But this is really new to me. Or am I dreaming? Any help would be appreciated.
