I am at a marina in a grotto along a large lake that connects to the Tennessee river in Kentucky. I opened and looked at this cheap hunk of plastic thinking that it was wasted money. I lightly blew on it.
It not only hurt my ears, but everyone within sight was looking for a large ship that was using it's horn. People were running out of buildings looking for the ship. People working on boats were looking out over the water trying to find the souce of the horn. Everyone within sight had heard it well. This baby is LOUD!
The only problem that I can see with it is the fact that is is made of thin plastic. It looks like it might break easily.
Beyond it being fragile, this puppy could replace any horn that you have on any boat.
