Golf GPS or Radar
 

I was told on the course one day that these devises should be outlawed as they cause slow play. Sounded reasonable to me at the time, but I have watched those that use them, and I see ZERO slowing of play from the folks I observed. If anything, if these devises helps the golfer miss water/bunkers etc, I would be more likely to see them as a means to speed up play and not slow it down. Just my observation.

Did this information come from a bush??

If anything, I would think a GPS would help to speed up play. Without a handheld measuring device, one would walk to the nearest marker and pace off the distance to the green. In my opinion, that would slow things up more than using a GPS. Just my opinion!

I use the guestimate method. Look at the marker and pretty much guess how far it is from my lie to the green. Since I am not playing for $1,000,000 I can guess close enough. And I am not usually that much off from the GPS devices.

Looking for a distance marker (which can be difficult on the Championship courses) and pacing off takes much more time than using a GPS.

I've been using GPS for several years now and I honestly think it speeds up play.
I just take a quick glance at the GPS see the yardage and select my club.

I played Golden Hills Golf Course in Ocala last week and they had no markers except for out of bounds. My Callaway/Nikon laser gun came in real handy. That course is loaded with trees (designed by Reese Jones) and they're not palm trees, big oak trees and loads of sand traps. It's real nice to know the distance not just to the hole but to bunkers and other objects which a laser will tell you. You can take a measurement in about ten seconds and you'll find out those 150 yard markers can be quite a bit off depending on the placement of the pin.

I guess the person who has told you that never saw golfers walking off the distance to be able to select a club.
