I have several 1000 ft. of chain, most of it is in 5 ft. pieces with a swivel in the middle and 1 on ea. end. Set up like this I can put a piece of chain on any trap I need to and if I dont need it its not in my way. I use 1/8 quick links to connect my chain. The 1/8 will fit in the hole on the end of the swivel, makes a solid connection. I have 7 330's in a run with 13 pieces of chain on ea. one to get it to solid ground. Have to use a boat to set because of the soft bottom. I start with 10 traps, when I make a catch I drag him in, when I get down to 3 traps I'll unload the boat and reset the 10.
