Do you have any friends or relatives as tour guides? If you do, you could take much time to consider what kinds of gifts you should present them? In fact, here is a good suggestion for you, and you could present them a laser pointer pen, because it is not enough for them to explain or illustrate briefly at some touring places when they lead a team to visit scenic spots, and at this time they need a tool to lead tourists, making them understand better.
We know that sometimes even though tour guides speak very loudly, some tourists still could not understand what they are talking about, and they do not know what they are pointing at. If tour guides could have a laser pointer pen, they could make tourists see those scenic spots that they are explaining, and in this way both tour guides and tourists could save much energy and time.
There are several kinds of laser pointer pens on the market. At present, there are red laser pointer, green laser pointer and blue-purple laser pointer mainly on the market. Red laser pointer has red light which is 650nm to 660nm in wave length, and it is a kind of laser used on DVD disks, and actually it is the earliest and the most popular laser pointer pen, and it is also the cheapest on the price and belongs to semiconductor laser. Green laser pointer has green light which is 532nm in wave length, and it belongs to a kind of solid laser, and it is widely used in stars pen because of its high visibility. Green laser pointer could send out a shinning green light beam in the dark sky, and it could point the places of stars to people easily. Blue-purple laser pointer has blue and purple light which is 405nm in wave length, and it is used on blue disks and gets close to UV-light, and it could stimulate fluorescence and could be used to check whether money is true or false.
I am sure that laser pointer pen will be a good helper for tour guides, and they could make their explanations active and attractive with the help of the laser pointer pen, and tourists could also show more interest in what tour guides are talking about at the same time.
Therefore, if you have friends or relatives who are tour guides, you could present them a laser pointer pen, and it will be the best gift they have received.
