GPS inaccuracy fallacy - Page 3

EDIT:  For most of us, 2 or 3 yards difference is no big deal cuz we ain't that precise anyway, but as you get better, you are going to want to know exactly how far things are.  Also, when I watch the "On The Range" show on golf channel I see caddies with lasers all the time, but haven't yet noticed one with a GPS.

As for just getting the number to the pin...it doesn't mean thats the number you swing for..it just gives you accurate info to base what shot you want to play off of.  There are many times when I'll shoot the flag and know that I'm going to be landing the ball well short of it..but it lets me know the club and the swing I need to try and accomplish that.  Doesn't mean I do it because I'm no pro..but it gives me confidence.

For the second part, unless you know with high precision where the pin is in relation to your target, there's very little objective benefit to having +/- 1 foot versus +/- 10 foot errors on your measurement. I guess if your target is just "one club short of the flag," then that's fine, but that's really not a situation where you're benefitting from the exact yardage.

 

Unless it just makes you feel better about it. There's a lot of value to that in this game!

The average player is just as likely to sheer one at a 45 degree angle right into those trees anyway. Why not just play to an area where you can see the ball land, then go find it and hit it again . . . instead of irritating the group waiting on the tee.

As others have said, I'm not accurate enough that pinpoint precision is required.  I like the fact that a GPS gives me front, center and back of green, 100-yard, 125 and 150 yard layups, bunker carries, etc all in one "reading."  

 

But, what I like even more about the GPS apps (Golfshot in my case) is that they track my round and statistics.  Lasers don't do that.  Sure, you can do it manually on the scorecard or enter it into your phone in scorekeeping app, but if you're going to do that, you might as well use a GPS and scorekeeping app.

 

So, I think the GPS apps have additional functionality that make up for a little less accuracy.  But, I have no aversion to lasers and will probably purchase one when I get good enough that I can actually target a few yards' difference.

But, come on, this is exactly my point. These shots don't come up very often.

 

The difference between a GPS and a laser is in the noise for almost everyone who doesn't already have a caddy with a precisely dimensioned yardage book. Each can do a few things that the other can't (or can't easily), but it's really, really rare that these things come up.

My friend that I play with a lot has the latest and greatest laser with slope but I still find my iPhone with the GolfLogix works better for me. Could it be he is giving me wrong readings trying to beat me?
