I personally like the Bushnell Tour V3 Laser Rangefinder myself.  Even on courses that have GPS, I find that the laser if far more accurate, sometimes as much as 7 yards.  I used to use a cally GPS and liked it because it gave a birds eye view of the hole but ever since I switched to the Tour V3, I am much happier. 

I use the SG5 from SkyCaddie.  Others in the group have laser range finders.  None of us have any issues with the GPS being off in yardages.  I move the cursor for hole location to an approximate area and am always within 2 yards of what the guys with the range finders get.  Some holes for them are hard to hit the stick, so they turn to me for what the yardage is and it's never been an issue in distance.  I wear glasses and have a real hard time with range finders, so I will always use the GPS over one. 

I also use the Bushnell Tour V3.  I have played many rounds with guys using the Garmin watches and what I like is I can quickly shoot a bunker or the corner of a dogleg.  Most of the time they are asking me for certain yards.

I switched from using free apps on my phone.  I will never go back to a GPS style.

I personally use a laser range finder. It wasn't really a choice, but rather a gift from my father in law. My playing buddy uses the GPS watch so I have the luxury of both. The GPS watch is nice because it'll give you a reading to the front, middle and back of the green which is what I prefer. The range finder just confirms where on the green the flag is (sometimes it's hard to tell from the fairway).

Both has it's pros and cons... another use for the laser is I like to measure the distance to hazards off the tee to help with club selection. Also, I think it's just a matter of personal preference... you can get around the golf course with either. 

I used to use laser, but last year I got a GPS watch as a gift and have been using it ever since. You don't get exact yardages to the flag, just front back and middle of the green, but its a lot more convenient since you just look at your wrist.

have both and Leupold with pin seeker technology is by far the best.  

I have used all sorts of things over the years. I used a Skycaddie, which was just ok, I used a Sonnocaddie, which I felt was much better, then I changed to my phone and have tried a lot of phone GPS apps along with my laser. 

I am set on my Golfshot GPS app for score-keeping and general distance and shot mapping. It has a nice feature that lets you flyover a hole and uses your measued shots or inputted distances for recommendations on which clubs to use. I use my laser (Leupold GX-4i2) when I am going for the flag. I love both and don't feel I can live without either of them. 

I use the Bushnell V2 and my friend just switched from a GPS to a V3.  We both felt the laser was much more accurate.  I also just played last weekend at a course with a GPS cart and one of the guys in my group had a GPS watch.  There were times when his watch, the cart, and my laser were all totally different.  It's hard to say which one was correct, but if I had to bet, I would put my money on the laser being the most accurate the most amount of time.

Last year I took my first dive into the range finder game and ended up with the Bushnell Tour V6. I don't mind pulling it out of the case that I have hooked to my bag for yardage each time, after all, I have to go to the bag each shot anyways. It has proven to be extremely accurate and very easy to use. 

The only reason I did not go to the watch game is because I cannot have anything on me other than my golf glove. Watches, wedding ring, anything else is removed while playing. 

They both have their merits depending upon conditions. I only have a range finder and there are times when I wish I had GPS.

Like playing a new course. ("Who put that creek there")

Or in the fog.

Or on blind shots around corners or severely up hill.

But most of the time, the above can be avoided with just a little planning ahead before the round.

I have a Skycaddie SGX and love it. Never had a problem yet and is within 2 yards of the other gps and range finders in my group. 

I prefer a handheld gps.  It's quick and accurate and effortless!!!  No wasted time!!!

Leupold... Supports military and Police, so they get my money.

Sky Caddie SGX here. Have owned (and sold) my Bushnell as I prefer to see the hole layout, hazards, depths of greens, etc. I would have to consider a GPS watch once some of those handheld features are in the watches. 

I have used a Bushnell Pinseeker 1500 for almost 10 years and can't imagine using GPS. Used them at courses that have them on the carts and they're not bad, but will stick with my rangefinder. Interested in trying some of the newer generation rangefinders.

Laser will always be the best method for accurate yardage.  GPS has a good margin of error that in golf could make the difference between one club or another.  You will never see a golf pro relying on a GPS device.  What the GPS device is good for is quick yardages to several points on the course where close enough is good enough.

Basically, I use both....I have a Bushnell Laser for exact yardage on pins or objects, however if I have a blind shot or need distance estimates I use GPS Sky Caddie...

They both have their pros and cons...

IMHO

I have one of the original uPro GPS, and it has worked very well for me.  My game isn't pro level, so +/- 5 yards is okay for me.    But support for the unit is gone, and with it, my ability to download any new courses.  My only concern with a laser is will I be able to pick up targets like the edges of bunkers, ponds, creeks, etc.  The GPS gives me those carry distances, I need to know that a laser can too.

I have the Nikon coolshot AS. I used to have the sky caddie GPS but I just didn't like how you had switch the hole on it so that's why I switched to the Nikon.

A specific model of the Nikon you are using?   I have a Lot of Nikon gear and know they make great stuff, and the 40i I looked at was very light.

Thanks,

Mike
