Best measurement method?

I always end up stepping off my drives when I want to know the distance, this gets me close. I want to know exactly how far I've thrown. Does anyone have a concrete method like a laser rangefinder or something that can negate terrain changes and give a line of sight reading??

I have a wheel and laser. Just throw in a flat open space should be easy to measure. Handheld GPS works to within 15ft too.

Cool probably want the laser, here in Colorado most every hole is not flat so that surely would work the best, ya?
