Question for beach hunters. I bought the beach hunter 300 in July, and have used it about 8 or 9 times. Many times, I haven't been able to balance it, after reading directions over and over. Even a beach on Cape Cod Mass, where I grew up, I had a hard time balancing, no black sand or minerialization. Did find a few good rings there when I could balance it, but since I moved to Buffalo, haven't been able to keep it stable at the Lake Erie Beaches, beeps everywhere. Should I trade it in for the Excaliber? From reading and talking to people, seems like the best machine. I've been I coin hunter for a long time with the DFX. Desmond in Buffalo
