Hi everyone I have been metal detecting for quite a few years and found lots of gold with my Surfmaster PI. I am hearing alot of positive and negative responses for the Excalibur. I would love to get that machine but some people have been saying that this machine breaks down alot and has alot of problems with it. Then I hear that this is the machine to get to look for lost rings and avoid digging all the trash when water hunting. Can anyone help me with this problem and tell me their experiences and give me some advice. Thank You
