I just made a deal for a Whites Eagle II SL black box detector with two coils ( 950 and blue max 600). I hear that they made a blue box & a black box model of this detector, I will call it gray because of it's age . This is going to be a bit heavy and has a learning curve (there are many settings you can do if you want). I have heard that the Eagle was one of the best detectors White's has ever made, I don't know, but I did see they cost over $800.00 new. It should be here tomorrow, I was wondering if any of you have used one of these beasts. Steve.
