Golf laser rangefinders work by sending out an infrared laser light to a certain target. It looks like a pair of binoculars but only more powerful. In fact, the latest units are able to magnify images to up to seven times. The device measures the duration from when the light is sent until the target is reached. It has a very slim margin of error and is extremely precise within one yard. For greater precision, some units are also capable of providing slope readings. It is able to get a reading of the distance to any target without having to download maps. The unit is lightweight, sturdy, and remains functional for a very long time. It can also be used while on a practice range.
Despite its many advantages, the golf laser rangefinder also has its own share of disadvantages. Bad weather can make it difficult to obtain an accurate reading. Using this device also expends a lot of battery power. A person with problems in visual acuity would also have trouble in determining the right measurement because the user may be unable to see the target pin. A steady hand is also needed to obtain precise readings.
With Golf GPS units, a map of the course is downloaded into the device. The gadget also informs the users of any possible hazards to safety and there is absolutely no need to pick and then shoot the targets. All one has to do is to look at the screen and you are good to go. Some of the leaders in the world of Golf GPS units are Garmin, SkyCaddie, OnPar, Golf Buddy, and Callaway.
Using a golf GPS rangefinder is much more complicated than a laser rangefinder. The user has to estimate the location of the pin by way of a satellite signal. The reliability of information provided by a GPS rangefinder is largely dependent on how accurate the downloaded map is. These maps may be limited in such a way that they are only able to provide the distance to the anterior, posterior, and middle part of the course. Some other disadvantages of Golf GPS devices include the possible problems of a large error variation of, give and take, three yards and also the negative effects of bad weather on the ability of the unit to receive adequate signal. An annual subscription fee is obligatory in order to obtain maps of golf courses. This is definitely a major deal breaker for many golfers.Comparing Golf Laser Rangefinders and Golf GPS by Steven R
