I have a Vector IV range finder. It will take a little research but you can check these out online, as a matter of fact one was just recently posted on ebay. They go for 13K-14K online. Make me an offer. This obviously isn't for everyone but to the right big game hunter, prepper, collector or someone who just likes to say "oh, what the hell" this is an amazing piece of modern technology. I am putting a link in to a site that has the user manual so you can read more into it. Please do your research on this item so you can see just how worth it this is. You can check ranges (Yards, meters, feet), track the drop of your bullet when targeting in, see angles, triangulate, check speed (KPH/MPH) and much more. This comes with the range finder with battery, carrying case and computer cord. I am looking to sale or trade for any reliable pickup but don't be shy and make me an offer. Below is the link for the user manual. You can contact me via email for any information, additional pictures, to make an offer or to check it out.
