I was looking for a stringer that doesn't have metal parts.  I fish in salt water and everything rusts or corrodes.  This is perfect for any application, the loops are secured closed, there's a definate snap, when the locking mechanism closes, and the loop feeds through on gill of the fish, and out the mouth, or visa-versa.  Theres enough extra cord at one end to tie the stringer to anything, even ourself.
