Just got the Medalist as an early Christmas present from my wife. BEST...THINGS...EVER!!!!!!!!!!! I don't have the steadiest hands for this - at least when I was getting yardage fro more then 150ish out it seemed like I was having difficulty keeping the flag in the crosshairs. Didn't matter - the Pinseeker feature worked like a champ everytime. I'd get the distance to whatever was behind the pin, then a second later the closer distance would show up. I would check it 2-3 times at first just to be sure, but after just a few holes I was convinced that the yardages were accurate. I played an extra 18 yesterday in large part because I was so amped about using the range finder again and again. I guess it would be nice to have higher magnification than 4x, but it's more than enough for me. I could care less about slope either, I'm not that good.
I've used phone apps for GPS, they're OK, but they're not always accurate and it's a hassle toting around and unlocking my phone every time I'm shooting. I've played with people who use simple "Front/Middle/Back" GPS devices and they are much more useful for the average middle-hogh HCP golfer, in my opinion. But when you need really accurate distance to the flag, the laser is where it's at. I can't tell you how many times I "guessed" at my distance based on where the fairway markers were, only to be 20 yards or more off because of a weird angle or deep green. When I normally would have maybe hit a 56 because I though it was 95-105, it was actually 118, and I would have been screwed. I then hit a 52, and bam!! Pin high on the back of the green.
