Had time today to get out in the yard to detect with my new 5.3 eclipse and Sunray Pro Gold headphones and I must say its like night and day as compared w/ my 12" coil and headphones that came with the unit. I had dumped a few coins around on my lawn and w/ my old setup, I got very erratic readings and I was having trouble pinpointing with it but with the 5.3 and Pro Golds it was hitting them hard. The coins had been there all summer so they were covered over w/ dirt. I think I'm in heaven... and now I find that my J.O.B. is interfering with my hobby.... whats a guy to do??? Jack
