Usually in the summer my family and I go to some resort to have fun and swim in the ocean. There is one minus in those trips: it is really hard to find a Wi-Fi network in those places. It would look somewhat odd to walk around with your laptop opened so I decided to buy a Wi-Fi detector.These electronic devices can detect a Wi-Fi network and you do not need to walk around with your laptop. There were many detectors however they all were big and expensive. Then I have found a cool Wi-Fi detector from the Informatica Company.
This electronic gadget looks like a regular pen (it can even write) but it has a detector that will allow you to detect any wireless network around. There is one disadvantage though: this pen can detect a network that is not further than 15 meters which is 50 feet.
It is not that effective because it does not have a normal antenna. However, it has some LED's that will show you the strength of the signal. There is green, yellow, and red LED's to show you that. The cost of it is one of the best parts about this pen. It costs only 19 USD so almost anyone can buy it. However, think of how odd you are going to look walking down the street with this pen in your raised hand, before you buy one of those. It does not matter to me though so it remains my best gadget that I have.
