I found on the web an annoucement, that promote a secret of old fishermen that evidently increase you fishing rate, it cost something like a new rod, I'm just asking any kind of comment!

LOLOLOL  This makes the rounds once every couple of years.  Evening Secret, Walleye secret, Crappie Secret, Catfish Secret... many other names.  It's certainly no secret that it's a submersible light that may or may not increase your catch rates.

Don't waste your bucks, go over to bass pro and buy the same light for $200 less.

Don't bother.

He is talking about dropping Rhodium Oil ( or ore) in the water I think. Years ago the Egyptians used it to draw fish to an area. Every now and then someone comes up with a scent with this in it claiming how well it works. Cedar oil is another one. Indians used buck eyes ground up to drug fish if I remember right years ago.
