Hi wizid,
Despite what the nay sayers claim, there is plenty of value to newcomers to the sport from a wind meter.
Our sport has developed to such a point that loads of non water sport people are giving it a go. If you have never been around the ocean or wind sports before, learning the appearance of sea conditions is made far easier when you have a wind meter to back up your guess.
Cross checking water appearance with what is shown on the LCD display will teach you quickly what it should look like. Going to different locations, run in or run out tides, and different wind conditions can often give misleading appearance of water and wind conditions. This is learned through years of being in and around wind/water sports, but you need to gain this experience first and the wind meter is the perfect device to speed this learning.
It's funny how it's deemed uncool to have a wind meter on the beach and yet so many people come up to you and ask what it's blowing when you do

This is just people cross checking their guess.
There are plenty of cheap wind meters around and are accurate to within 2 or 3 knots. We sell the Kaindl Windtronics unit which is more expensive, but is a very accurate instrument.
Either way, they are a help to those new to the sport.
