I bought the laser rangefinder both for golf and to use in Civil War field studies. It has performed well for both uses. It is amazingly fast and accurate on courses that use corner reflectors on their flags. Also, in my field research I've used rocks, monuments, trees and other available objects at up to 1,000 yards to get readings. So far it's performed entirely as advertised.
Pros: Ease of use; quality
Cons: Haven't found any yet.
