Those floats with the hook thingys are designed to clamp onto your line. Work out the depth you want your float to be, then with a finger on the hook at the bottom of the float, push down on the button at the top and hook your line under the hook. Then hold the hook on top with your finger and push the button down so the hook pops out the bottom and hook your line under it the same as the top.

Confused? so am I ,its easy to do hard to explain! ??? ??? ???
