Starting December 18th, there was a thread on safety gear, which
included a discussion of a "Blaster Horn" that was reported to be
amazingly loud. Included in that thread was a discussion of the size of
the horns, some of which were reported to be on the large size for
paddlers, with some of them somewhat smaller. Someone claimed that there
were two sizes. Unfortunately, now that I am ready to order a horn, I
am confused about which one to buy.

SeaSense makes one of them, a SeaSense Safety Blaster Horn, usually
portrayed on the web as white with an orange mouthpiece. The discussion
thread indicated that there were a couple of sizes of SeaSense horns,
but they all look the same on the web.

Orion makes a Safety Blaster Horn, usually shown on the web as a carded
product, all orange.

Apparently there is a company called "Safety Blaster" that also makes a
Safety Blaster Horn, black and orange.

If you go to amazon, and search for Blaster Horn under Sports and
Outdoor category, you can see three horns side by side on one page. For
all I can tell, they are identical except for brand name and color.

On pygmyboats.com, I found a Safety Blaster Horn with a white mouthpiece
and a blue body.

Unfortunately, none of the ads seem to tell you how large they are,
although some ads mention 1.4 oz. They all look like they are the same
size and design, just different brand names and colors. Some of the ads
even say "assorted colors". They generally have lanyards. The cost
varies, but all are around $10 US.

So, which one do I order? How long are they? I am looking for
something to affix to my life jacket.
