Ok, so I was thumbing threw my new Overtons and I came across a Bennett Wake Tab, that says you can raise and lower this into the water to determine the size of the wake. I know that this is possible but isn't there some serious risks to your boat if doing this? Has anyone ever used one of these? Does it really work? Give me anything, not really thinking of getting one just curious. Here is the link to the site, this is just one but they have a few different models.
