Laser pointers have become popular with the average consumer, allowing them to purchase one very cheaply for a few pounds and being used for personal amusement, such as pointing them at other people from a distance and making them wonder where the light is coming from and using them to entertain their cat or dog which they enjoy chasing. However, there are many useful applications of laser pointers; they can aid someone in their job or be useful as pointing device for those who spend much of their time outdoors.

This article will list some situations and jobs where they can provide some benefits and help completing tasks a little easier.Laser Pointers

Presentations

Laser pointers have become widely used as a pointing device by many business people who do presentations on a regular basis for clients or business partners, enabling them to highlight important facts and figures in presentations slides to their audience that they will find informative and useful.

The have evolved away from the look of a generic pointing device into a more professional looking tool, taking the shape of normally either a pen (known as a laser pen) or remote control, sometimes called a wireless presenter or presentation remote control.led stage lighting

Many laser pens have a built-in pen, making them a handy tool for many business people who require both a pointing device and a writing implement to take down notes and will save them from having to carry two separate items with them wherever they go. They also make business people look more professional than if they were using one that was attached to a key chain.

Presentation remote controls are mainly used to control presentation slides in business or any organisation that need to convey information to an audience and will more often than not have a laser pointer built into the device. They allow the presenter to control the presentation without the need to be standing in a fixed spot next to the computer to click on the mouse to move onto the next slide and highlight certain information on the screen from almost anywhere in the room with the laser pointer.

Classroom Aid

Many teachers will find using a laser pointer a time-saving and useful tool when it comes to teaching a class full of children. There are many lessons that it can come in handy, making the teaching process a bit easier. When teaching pupils where a country is located in a geography class, a teacher can use the pointer to show them where it is on the map without having to stand next to the map throughout the whole lesson. Or in a biology lesson, a teacher can accurately point out specific parts of the human body on a diagram that children will see clearly.

Another advantage that it can bring is that a teacher can carry out a lesson from the back of the classroom so that they can keep an eye on their pupils' behaviour, as opposed to being at the front of the classroom and having their back to them while writing something on the board.

Outdoors

Laser pointers can not only be useful devices to have but they can also be a life saver. People who regularly go camping or hiking may find themselves in distress or in trouble at any point and will require assistance with their problem. However, the nature of being outdoors is that it can be difficult to seek help unless they are lucky enough to have someone walking past at the right time. With a laser pointer, they can attract someone's attention from several hundred metres away, which can hopefully rescue them out of their situation. In cases like these, they can be an invaluable little tool.
