Pros: Small, very easy to use, light.
Cons: Noise, hard to see
I was resistant to rangefinders for a long time, foolishly thinking that GPS was the way to go. I thought that I'd have too much trouble with blind shots, or thought that I'd have trouble using the rangefinder. I was wrong. It is sooooooooooooo easy to use, especially in scan mode, that I know exactly what my distance is. With GPS, I could get pretty close by guesstimating the location of the flag on the green and interpolating between front and middle, or middle and back. But I could never know exactly what that distance was. Plus, most greens aren't perfect squares or circles, so that tiny bit of doubt left in your head after using a GPS is no longer.
It has taken a couple of rounds to get comfortable in how to hold it steady, but it has become pretty simply, pretty quickly. It will shoot anything you aim at, so you have the power to pick out the flag, the lip of a bunker, hills, people, whatever. It also has a "lock" feature that will beep at you whenever you pick up the flag (assuming your course has flagsticks with prisms) while using it in scan mode. This is handy when you are faced with features beyond the green. The beep lets you know its definitely the flag and not that tree behind that it picked up. On the other hand, I've found that it's not that difficult to pick up flags without prisms either. When in scan mode, just keep an eye on the readings. You'll know you are about 160-170 out from course markers, so when it flashes 210,200,205, 166, 205 ... you know that 166 is your number.
And those readings come quick too. There is very little lag time. Press the button, and boom, theres your number. Besides scan mode (which is just holding the button down and allowing it to give repeated readings) there is the one touch mode too. Point, press the button, read the number.
I've also found it easier to use little tricks like shooting the guys putting while you are waiting. I can see this guy is putting towards me, so this number will be a little long. I can see that guy is standing near the front edge of the green, etc, etc. All of this information adds up to extra confidence for me.
The one thing I don't like about this rangefinder is that when it locks on the flag, it beeps. I would prefer it vibrate like the Bushnells, because I don't want to have to check and see if my playing partner is about to swing while I'm getting the distance and I don't want to distract him. The upside though, versus the Bushnell v3, is that it only locks on the flag. The v3 (I used a friends for a few holes the other day) appears to lock on other features as well. This seems like it would be hard to differentiate between the flag and something behind it.
Lastly, I wish the thing wasn't black. It would be harder to lose if it came in a bold colors.
But, all in all, I really could not be happier with this rangefinder. It didn't hurt that I got it on sale (Christmas time) form the regular price of $299. I have only owned it for about 2 months and 4 or 5 rounds, so I will come back and update this review once I have more info on the battery life. So far so good.
