Hi D/P not heard of that but there is a method thats used with the pole and a big float to catch carp up in the water which was nick-named the rattler, a self hooking method and got its name by the noise that was made when a fish was hooked,
Thanks lads for yout replys,
I am not what you would call a "CARP ANGLER"
but I do fish for them on occasions and, had
not heard the term before and, Yes it does
sound a bit barbaric to say the least.
