Basically, ages ago i saw south somerset ferreters use one on fieldsports channel . a normal longnet set high so theres a gap for the rabbits to get under then they pulled a string when a number of rabbits were in the field and the net dropped.Anyone made one of these or no how too . . Btw its for land that would normaly be difficult to longnet because the lands not right or the rabbits dont venture out enough to be able to get into position ??? Cant explain any more really only seen it that once i think they used box section but not 100% . .
