Any fishermen out there use the green fish lights that attract baitfish and zooplankton? i am thinking about picking one up, but i'd like to hear everyone's opinion of them and how they work or how they are rigged (how deep to put them under the ice or off the bottom). i've only heard of a few people using them, but never hear how they do. i guess if they caught crappies like mad everyone would have one. so, if anyone is in any way familiar with the green light, let me know, and let everyone else know as well.
