I have bought many products from this company and seen this item on sale and it would be great for the kayaker or a canoest and a boater. The company is called Heartland America and you can see it on the web or get a cataloge sent to you.http://www.heartlandamerica.com/bro...A1000&

Try this site. A bit more expensive than the one you mentioned, but a good product that has been tested by some people I know and they give it the big Thumbs up.
