The Silver Eagle was 2nd in line to, I believe, the Eagle Spectrum. The big difference was the programming, the Silver Eagle didn't have the ability to save programs. I have hunted with the Silver Eagle since the early 90s with one that I purchased new. The detector has always been reliable. I have the 9.5 in, 8 in and 12 in Hot Head coils for it. Still enjoy hunting with it any time I get a chance.
