I'm a little disappointed in the one I got... it sure seems to highlight all the dust that's in my barrel!

The pic looks a lot clearer on my monitor, took me a while to find the light control on the USB plug...

A little better pic, closer to the white card I'm using to reflect the light.
Still, an excellent little tool to view the condition of rifling... and what I'm especially interested in, the leade. Using the 7mm one, it just fits inside the barrel of my .30-30... And answers a question I've had for the past several months. I've VERY seldom fired any jacketed ammo thru this gun... but a few years back did kill a nice whitetail buck with a Federal Hi-Shok round, after verifying the POI is the same as my cast stuff. I guess I only thought I got all the copper out of the bore!

Since this is a much tighter fit in the bore, a LOT more light is reflected off the sides of the bore vs. the .45 Colt bore.
