What is your experience with laser rangefinders on the golf course? Do they really work? Are they worth the $? - laser rangefinder repair reasons i enjoyed this book

I think that buying a laser rangefinder for golf as one of Bushnell and Nikon, and I am skeptical as to how they work - such as raising a flag or banner of 200 meters with a background noise. What is the distance from the danger, like a bunker or water hazard? If you've used one and have an opinion, I would like to know. Thank you.
