Floating a crawler is apparently an outdated fishing style.No thanks to all the modern thinking folks on this forum,I eventually figured it out A floating night crawler is used when fishing from the bank,basically the same set up trout hunters use with power bait.the tools required is a small syringe and a thin wire with a notch filed in one end to accommodate the hook.The tied hook is inserted into the crawler with the wire just behind the belt,pushing it to the tail end,but not out.
The syringe is then inserted into the crawler in two or three spots and air is pushed into the worm just enough to puff it up a bit.Using the Carolina rig set up,the crawler will float and wiggle for a surprisingly long time at whatever distance off the bottom you desire.The pros of this set up is the crawler is constantly moving .......The con is,the set up time takes a minute longer to set up than fishing artificial. I’m not suggesting this is a crappie set up,but many species find it pretty appetizing.
