Magneto speed v3 - MagnetoSpeed V3 Ballistic Chronograph Kit with Hard Case

Works flawlessly and very easy to use! I have used it on 4 different rifles now and after reading just the section on set up I was able to go right to work with it in just a few minutes time. The menus was very straight forward and easy for me to navigate and use. It included a micro sd card and battery right out of the box too!
