My mother-in-law just bought me a rangefinder for my birthday. It's something I've been wanting for years, but could never talk myself into paying for. Any time I had that kind of loose cash laying around for shooting purposes, it went into another gun instead. Anyway, it took me about five minutes of playing with it to realize I've been underestimating distances up close, and overestimating them far away. For example, I figured seventy five yards for something a hundred yards away, but five hundred yards for something four hundred yards away. I'm curious: what was the experience of some of you who tried a rangefinder after years of guesstimating by eye? How closely did it correlate with what you thought you had been seeing?
