I saw this type of "Safety Blaster Horn" blaster in Boaters World and its
alot bigger than I would want on my PFD. Is there a smaller one like 3"- 4"
instead of 8". The one I saw remains me of a bong.

Yeah, there are two sizes and the smaller one is hard to find. I think
the one at the FogDog link is the smaller size. According to SeaSense,
K-Mart sells the small ones, but I've never seen them in the local
stores and they're not on their web site either. Dick's Sporting goods
carries them, too.
