In two weeks I am going on a weekend trip on Dale Hollow Lake with some friends. We rent a house boat and also bring our boats. I thought this year I would try hanging a light off the house boat at night and try to catch some crappie while enjoying our favorite beverages. LOL What is a good green, led submersible light to purchase? Also, do I need to bring a separate 12volt battery for it? Any tips on how to catch the crappies with the light in two weeks on a clear Dale Hollow Lake? I sure can't catch any during the day time there. We go out of Holly Creek Marina so the houseboat will be tied to a bank not far from there.
