Don == I own a EXII that I bought this spring. Today, I had it out in a field that was once an Indian village and colonial residence. The detector drove me CRAZY. Every time I did my swings from side to side the EXII would worble, screech and go into contorsions. I tried every setting to get rid of the problem of its weird behavior and really started to think that I was under an old indian or colonial curse for detecting this site. Well, I finally figured it out--------- I just bought a new pair of rubber boots (it just stopped raining) And I was detecting the internal (metal) arch and toe guard of my boots at a good distance away from the coil. Really, I really like the EXII very much and have been doing well as a newby. Last week I found a real colonial era handwrought ax head.
