Attach 3-way swivel to the wire leader
First you need to get a wire leader and attach a 3-way swivel on it. You can do this with help of a knot. This knot is also known as a haywire twist.
Attach hook to the wire leader
Now you need to attach a hook the opposite end of the wire leader. You can do this with another haywire twist. Keep in mind that after tying it, the shark leader should have length of 5 to 6 feet.
Weight to hold the bait
After attaching the hook, you need to make the weight which will hold the bait still. Take a jug and fill it with beach sand or any other sand. Then you need to tie an end of the mono filament leader to the jug handle. Tie the other end with a 3-way swivel. Remember that it will act as bait but when the shark bites, it will break from the line. Thus you should not worry about the breaking and focus on catching the shark.
Attach the bait to the hook
Next you need to attach the bait to the hook. You can use lady fish or blue fish which are great options for using as bait. Remember to cut its head and tail before placing on the hook.
