RE: Which laser rangefinder?
I've owned two Bushnells: The 400 and the 600. Very reliable, but they both read a yard short (not a big deal, but it would've been just as easy for them to get it right), and both lasers hit below the reticle box (could give you a short reading at the wrong time; another thing they could've done right without spending an extra dime).
I got tired of toting both a laser and a bino, so I finally sprung for the new Wind River 8x32 bino/rangefinder. $700, but worth it to me.
