There is no substitute for a laser rangefinder as far as accuracy is concerned. Plus or minus 1 yard. For convenience, not so much, that's where a GPS is better, a talking one even better. The other advantage to a GPS is late in the evening or in the other fairway, over a hill etc. where you can't line of sight the flag. That being said I only use a rangefinder. I have a free GPS app on my phone but never turn it on.
