The newest trend with radar detectors is devices that generate laser lights using a semiconductor. This new technology far surpasses the older radar detectors that uses radio signals to detect police.

Detectors that use lasers, also known as "ladar," are the cutting edge and users experience fantastic success with the newer models. Since police now use guns that are a combination of laser and radar, these radar detectors work by picking up the laser portion and transmitting a sound to warn the driver of their speed. Some police and state patrols are now using narrow laser beams, which are much more difficult to detect. The older radar detectors are completely at a loss when it comes to these narrow laser beams, but the new laser radar detectors can detect these beams, although the advanced notification is severely limited.

For the most part, laser detectors offer a faster lock-on time, which averages around one-third of a second. The laser beams are confined to a limited spread, usually around six feet for about 2,000 feet of space. This allows the beams to be recognized more quickly, giving the driver more advanced notice.

However, laser detectors come with some drawbacks. For example, particles, including dust and water, can limit the range and confuse the system, so your laser radar detector may not work at top capacity when it is raining or snowing outside. Furthermore, some surfaces are unable to correctly read laser radar, so the environment can potentially make all the difference.

Traditional radar detectors use radio waves to detect when a radar gun is in use. Many police and state troopers still use regular radio wave radar guns to patrol, so these detectors are able to pick up these guns. However, radar detectors are unable to pick up laser radar guns, so drivers will be at a disadvantage when it comes to detecting the latest technology. These traditional radar detectors can be easily confused by other non-radar gun devices, so this may play a factor into your purchase.

In the end, choosing a good quality detector is the key. A traditional radar detector of good quality is a better choice over a poor quality or cheaply made laser radar detector. Before you decide to buy any type of radar detector, do the appropriate research on a brand name and a type that will meet your needs. A simple internet search will provide you with a wealth of information regarding all different types and brands of traditional radar detectors and laser radar detectors. Once you have made your selection, visit your local electronics store or favorite internet retailer to purchase a device that will be backed up with an appropriate warranty that will protect your purchase in case of accident.
