Do you guys just let the lights down over the side of your boat.

Or

Do you attach the light to a pole to get it a little further away from the boat. Before the light enters into the water?
If you use a pole how long and why?

My longest rod is only 7ft if that makes a difference. I will also be in about 20fow or less. With two 1000 lumen submersible green lights.

Thanks.
