I am in the market for a new rangefinder. The Blue Tees rangefinder I have fluctuates a lot, and is unable to pick up pins without sensors or objects, such as trees. I see that the Callaway 300 pro has a pretty good deal on Amazon. I was wondering if anybody has any information regarding this rangefinder from experience? Also, if not the Callaway 300 pro, what is the next best option that doesn't range over 250?
