Laser rangefinders determine distance to targeted objects by sending out a laser
emission and measuring the time for the reflected emission to return to the detector housed in the rangefinder unit. They are primarily used by golfers and hunters to determine distance to potential prey.
Reflectivity refers to the amount of laser emission signal that a target will reflect back to the emission source, which, in this case, will be a laser rangefinder unit. Highly reflective targets can be ranged at greater distances than other similarly sized targets.
Laser range finder models will have different effective ranges and performance characteristics based on their design. The strength of the laser emission and sensitivity of the unit's detector will determine maximum range to target determination. Laser rangefinders use batteries in two main sizes: CR2 and 9 volt. You'll find that the smaller CR2 is used by the vast majority of rangefinder models. Battery life tends be around one year.
Body construction is of the utmost importance when selecting a laser rangefinder. Depending on your intended use environment you may need a rangefinder which is waterproof. In addition to waterproofing, rubber armored body construction is available in many models.
Golfers have to decide the type of golf rangefinder they need by the level of golf that they play. Play a lot of high end tournaments then it would be wise to splash out a little bit more for a top of the range golf gps system. You will benefit in the long term. Not only will your handicap improve but you could be continually in the prize money.
A golf rangefinder is an excellent training aid and will help you develop skills in choosing the correct iron for the shot. For more experienced golfers, rangefinders will enhance your ability to take into account such factors as temperature, shot angle and even altitude. Regardless of your skill level, this site offers all the information you need to make an educated decision on your purchase of a golf laser rangefinder.
