I've tried using a laser range finder to measure hole distances on a course, but we couldn't get it to work because of the lighting conditions (shady course on a sunny day), and because we couldn't keep the laser steady enough in our hands for it to get a "fix." If you have the right tools, like a survey stake and a tripod, it would probably work.
Another thought: you will find it very frustrating to measure fairways with a 100' reel tape, even if you have a friend. You're going to want one at least 300' long, unless you have a pitch-and-putt course. You would be amazed how long it can take to anchor the tape, run it out to its full length, mark a spot, reel it back in, measure the next section of the fairway, etc. And it's terrible if you have a busy course where players are waiting for you to measure.
I'm in the VERY beginning stages of the course design. All I have done so far is walked the property with my range finder and a map to make notes on. So far I haven't had any issues using it, but we'll find out. Thanks for the heads up.
