This new model from ZooKeeper uses clear spine proof plexiglass as opposed to the old white plastic so you can now see inside. The 7" diameter tube contains a back end that drains water but does not allow spines to poke through. This can be easily removed though for easy access to your catch at the end of the day when removing lionfish from the container. There are molded in rings on each end with an attached lanyard or for clipping to your BCD.
Get the ZooKeeper 20" spear holder. It mounts on the side of the ZooKeeper and holss your lionfish polespear.
The 20" keeper can hold a maximum of 14 pounds of fish.
