a roepstok is a rod that is used to roep, a method used to catch barbel. the rod is usually quite a bit longer than usual and is used to dangle a loodkoppie a meter or however far from the tip. you tap tap tap swirl swaai swirl the surface and a whiskered friend hears the surface activity and on his way up sees the loodkoppie dangling infront of his snout. its so irresistable that he chows down and fish on.
the rod is also a through line rod. meaning it has no eyes and the line runs along the inside of the blank so that the dense vegetation in which one usually calls or roeps doesnt tangle the line
