Used very little. It is NOT the new G2 model, which replaced the Sport 50. I will email pictures if you would like. I will look to see if I have the training video that comes with it. Here is the owner manual http://www.tritronics.com/manuals/sport_manual.pdf
$100 cash or would trade for a 6x42 Leupold +cash.
Here is some info on it.
