Thinking of purchasing a Humminbird 580 combo GPS.... Who has experience with this unit and would you recommend it. I know there are better units out there but the 580 is within my budget and the others are not..I would like to shoot the transducer through the hull.. Whats the disadvantage of this, if any?... Let me here some feed back please..Thx.. David.
