The answer is, yes, you can use a single laser rangefinder for both golf and hunting, if you are careful to choose a laser rangefinder that has the appropriate features and menu options for both golf and hunting. Not all laser rangefinders offer this versatility, however, so you need to read the specs, carefully. Then, too, laser rangefinders that work for both golf and hunting will typically cost more, but not as much as buying separate laser rangefinders for golf and hunting.
Golf Laser Rangefinder
First, let's look at what makes a golf laser rangefinder perfect for hitting the links, then do the same for a hunting laser rangefinder. This will explain why you need to be careful when choosing a laser rangefinder that can be used for both golf and hunting.
A lower priced golf laser rangefinder has what we call nearest target priority software - software that automatically seeks the nearest target, namely the flag, and at the same time ignores distant objects beyond the flag. This makes sense, because the flag is always the nearest target, unless you happen to find yourself back in the woods after a bad shot.
Hunting Laser Rangefinder
A lower priced hunting laser rangefinder is equipped with distant target priority - software that seeks distant objects and ignores objects that are close. This is variously called zip mode, brush mode and so on among the manufacturers. This is very appropriate for hunting because you are nearly always in a situation where you want a laser rangefinder to ignore close objects and seek game beyond the brush.
