The Ultimate Safety Carp Retention Sack is designed for short-term carp care, featuring a collapsible design that folds neatly into its own external pocket for easy transport. It comes equipped with an H-Block sack location float stored in a Velcro pocket, ensuring easy location should a carp escape the retention cord. The sack is made from air-flow loose weave material for optimal water exchange and fish safety, along with a heavy-duty rot-proof retention cord, added durability with an extra tough clip, and a secure metal ring for effective use.
