i know exactly what you are wanting as i know 2 elderly gentlemen that cant/dont want to throw a cast net. they have a covered slip and have a pulley attached to the top and a very thin cable that goes down to and upside down umbrella style net. for years they used a white light attached to the side of the slip that shined down in the water, they turned it off and counted to 5 when they started raising the net and caught all the shad they needed until the heat of summer usually august and sept and the pickings would get slim. 2 years ago i gave them a green pool light bulb that they replaced the white light with. it is much dimmer than the white light, however i dont see much improvement in the numbers of shad they catch, but it attracts a lot fewer bugs so thats a big plus
