they are an advantage, but you do have to adjust the output this year at bouy 10 we were running alot hotter than last year to get fish and took us a day to figure that out but once we didit really made a difference. I think the more you use it the more you will like it. One of the really cool things I have learned to if you have seals around your your boat just turn it up to the max for a little bit and they fly away have saved some nice fish on the hook by doing this!!!!
