Which do you guys use? and which do you like better? both have their advantages and disadvantages and i'm not sure which i would rather have.
tdogg21, it's almost player preference. I have both the laser (Nikon) and a GPS (Upro). They're both pretty good and it would depend on where I use it.
I like that the GPS are quicker and it shows a layout of what I can't see. Keep scores and other stuff.
I also like the laser as I can point and shoot to targets, lay up, pin, use it at a driving range, check the carry, and it is very accurate.
I use the laser more than I use the GPS because I'm always playing the same courses. But I use the GPS on courses that I'm not very familiar with.
Good luck on your search. (I hear Garmin is very good)
