Just recieved my copy of H/F NEWS. Anyone else notice the tip(?) from John Kiezer about using something called a SALMON SCENTER?

According to John, just attach this scent holder to your downrigger and "dramatically" increase your catch. Don't know if he has any personal interest in this product, but I rarely see him make a statement like this.

Anyone else using one or seen them available on the shelf? Besides a black box, this my be just the ticket. You think?
