I haven't caught crawfish from a net in about 20yrs and was wondering how long of a pole do i need. I vaguely remember me and my dad going and know that we used a push pole but don't remeber how long. Also if the water is a little deeper than my nets can I just wrap coat hangers around the top and slide my net under that. Like I said it's been a while but got a wild hair to go catch my own with all this water.
