A watch is quicker, how can it not be? It isn't as accurate but it's clearly quicker. I can look at my watch as I'm walking to my ball. I've got the yardage at the moment I stop. With a laser, you stop, device out, zone in, press button, read yardage. It might only be seconds but it's more than a glance at a watch.Voted the wrong thing. Nice one
I've used pretty much all the options down the years. Watch, phone, handheld unit and laser.
I like the laser as you are also scanning the hole visually while taking a couple of yardages.
Nothing is really quicker or better. All shots require a certain amount of thought and processing. Read the lie, check the wind, assess the shot.
