This is an "outdated" model but does everything and more I need for $100+ less. Big differences with newer model was the number of data points stored, 2,000 versus 5,000, and the Bluetooth connectivity with idevices is there versus just android stuff on this one. There might be some new program that fixes that though. Odds are I won't get much shooting advantage with it till I get that 50BMG in the arsenal, been waiting for a certain new company to get off the ground for one of those
