I get where you're coming from Brent, totally. And while I've never owned or carried one of those rangefinders, I HAVE played a course where they had the gps built into the carts and found it all a bit of a hoot. Pretty much unnecessary, in my opinion, but fun for one round, anyway.
But everything you say seems to diminish your need for that device. In the same way that I know from repeat play that the bunker's appearance is a deception, you would also learn your distances, and feel your shots. Dude, use the thing ! Go for it ! I'm not on a high horse about it, I just don't happen to use one. I sort of feel the same way about using distance aids as I do about getting tattoos. When I was a kid, people like me didn't do that (distance aids back then equaled "using a caddie," and they didn't have them on the courses I was playing, and tattoos were for guys who had been in prison or in the Armed Services). And now that they are ubiquitous I still find myself uninterested.
What I think I'm talking about Brent, is not some sort of pop-up-book quality to architecture, I'm just talking about what I enjoy doing. How many times do I have to say "Do whatever you want?" I'm not making fun of you, I'm not calling you out. I don't care at ALL what you do. On a given day, I might do the same, if the opportunity beckons. I'm just stating my opinion, and having a conversation. And as to your scenario regarding the placement of a pin either in front of or behind a ridge......would binoculars do the trick? I wonder where Melvyn comes down on this whole "binocular" issue. Is he a Phillies fan?
