It's time to replace my Leupold RX-II rangefinder. It still works and have no issues with it. I just need (or should I say want) to upgrade them as I will be using them for an elk hunt this year and want something that ranges further than these do. I don't want to spend $1200 but probably willing to go maybe $5-700 for a new one. Please give me your preferences based on experiences you have had with yours and tell me what makes them better than any other brand out there.
