Took the Impact back to the old rail yard yesterday. Mostly hunted in DI3. I played with some of the other modes but DI3 works best here because of all of the iron trash and, believe it or not, copper targets. DI3 IDs the copper really well so I can avoid it if I want to. I did notice that the Impact does not jump on lead like the Relic does. The Relic LOVES lead. The Impact loves odd shapes. Used the small coil.No EMI issues and there are power lines very near.

I finally found my first all brass shotgun shell, what appears to be a parasol handle, a few lead bag seals, and most odd, a huge chunk of something not copper. The copper looking blob is an example of what we find here...looks like copper. This blue/grey blob IDs higher than copper is silver underneath the "patina" and test for high silver content to an acid test. Nitric acid turns a creamy white color when it reacts and the red silver test acid turns a darker shade of red. No blue reaction at all. This spur was an intersection and loading area for a rail line that serviced a huge copper mine. The area is also known for its silver production. This large chunk was not found near the loading docks where all of the copper is found. I'm gonna have to take it somewhere for further testing. Cool piece whatever it is.
I'm really liking the Impact thus far and I haven"t even used most of it's modes yet.
