I purchased the Garmin approach Z30 laser rangefinder and I really like it. The laser feature is fast and spot. The distance to the back and front of the green is very informational. It locks on to the pin really quick and I got the vibrationevery time. However, I’m going to returning it to Golf Galaxy because I am pretty good at my distances and hitting near the pin. I currently have the Garmin approach Z82 and everything works great. so this unit doesn’t work for me and there is no benefits for me to make a $400 purchase for something that does what my current rangefinder does. Overall, it’s a great golf range Finder and it's even better if you have a Garmin gps watch. I hope Garmin adds the range relay feature to the Z82 since it would only require a software update.
