Hooked them up to my Silver and wandered around the back yard..First comment, the Cal rads are garbage can bound. There is no comparison between the Black Widows and the 8 ohm things I had. Since my hearing is off in one ear, I need to learn how to adjust the sound levels..Going into the neighbors yard, there were very interesting signals..I think that this is where I'll test the earphones out..The owner is about 8 years younger and said their back yard was always full of kids playing..Should be some coins from the 50's..House from the 1880's...Tomorrow night, am off to the carving club meeting..A friend bought an 1830's map showing where all the mounds are located in the county, and is making a copy for me..I don't dig mounds, but the workers lost jewelry in the vicinity,so a possible 200 more locations to put on the County map. Looks like 2009 is booked, and I'll be working on 2010.....Cordially Nad
