In a post with a title regarding Halibut techniques, the poster also asked about the use of downriggers. I replied and suggested that the poster research line voltage and how it may or may not affect fishing for kings. One person I have fished with many times swears by it being a factor to your success. How do others feel? Some electric downriggers have a built-in adjuster to control the line voltage. Do These work? If so, where’s the sweet spot?
