This holder from UK company MDC is top-of-range. Heavy-duty but lightweight aluminium pole with good handgrips and 6mm plastic-coated steel cable. The features of this holder are that as the cable is pulled through, around the animal’s neck it locks. So does not require constant tension. The cable is then released when ready, by pulling a small trip-ring mid-way down the pole. This is a superior device. Pole is 150cm long.
