The Rod Ruler is a measuring tape that goes everywhere you fish. Measuring catches up to thirty inches, it's ready the instant the fish is landed. Released fish are accurately measured without adding stress to the catch while you fish for a measuring tape. The Rod Rul-R eliminates guessing of the length of your catches and will help you be sure that your fish are of legal size. Made from the same material as boat decals, sticks to any rod.
I usually paint my own markings on my rod for quick reference...this just simplified it for me. My only issue was it just wouldn't adhere real well to my ultra light trout rod (too narrow i guess)
I've added these to a couple of my paddle shafts for handy measurement of my fish. So far, they seem to be holding up. Time will tell.
