First off I would like to say thank you to all of you that post on this site as I have learned so much about crappie fishing in general from you all. There is way more knowledge on this site than I could ever figure out on my own in a lifetime.


So here is my question I found a really good deal on 2 hds 5 gen2 units with lss1 box and transducer. I am hoping to find a hds7 or 9 in a gen2 touch or gen3 to go along with them. I want to mount the two 5" units at the console and the other unit at the bow. I am totally new to the "fancy fish finders" as my boat right now has a lowrance mark5. One of my questions is where is the best place to get my power supply for everything? The unit on the boat right now is wired into the original fuse panel that is powered by the starting battery. Is that an ok place to power everything from? Would I be better off to add another fuse panel dedicated to just my hds units and lss1 box or should I power everything directly from the battery with inline fuses? Also the hds5's I'm buying do not have the user manuals with them, is there a place I can still get one so I can figure out what size fuse to use on them? I am open to any and all suggestions as I have never had any experience with these.
