The two-ring 550mm diameter Yabbie Drop Net has been tried and tested on freshwater Yabbies and Murray Crayfish. It's built to last using quality materials such as two galvanised rings, a top ring (550mm diameter) with net tapering down to a smaller ring (350mm diameter). TIP: It is important to place the bait correctly. The best method is to tie a piece of string directly across the top hoop and secure your bait to this. Regardless of how the net lands, your bait is always going to sit in the middle, where the Yabbies or crayfish will be.
