The Crayfish trap LiNi is the result of many years of experience. The trap is very easy to handel. For instance 150 ready-baited, folded traps can be loaded in a normal skiff. The opened side and the big baite pin are two details which have made the trap famous. In the fishing tool test of the Swedish Fishery Board LiNi was best in its price-class according to the catch result and the difficulty to escape.
