I'm just curious because I've only seen a few laser rangefinders with slope being used on the course in my life. They must not be big sellers because at my club there is at least a couple hundred members that own laser rangefinders and I've never seen one with slope. Is this because you can't/shouldn't post rounds where a slope function is used or is it just because they cost more? I've owned 6 rangefinders over the last 20 years and have never considered the slope function models because I prefer to post all of my rounds. I've also never had any trouble adjusting for slope and I live/play in a very hilly area.
