Thanks for the respose Here are the answers to your questions (1) how many and what type of sonar units are you running? 3-4 units on all day will flatten a battery easily.I Run 1 HDS 12 Touch on the front and 1 HDS 9 (non touch) at the Console(2) Do the power poles have the bottom-following type mechanism that Talons do? IE do they constantly adjust to wave action and such? If you use them frequently, or use them in that mode, they drain power. once they are in they are in they arent like talons that keep hammeringThanks again for your help it is greatly appreciated
