Humminbird all the way.For the price they cant be beat.Humminbird has come along way .I have a 767 and it has 4000 watts of power and gps mapping.For 419.00 at Le baron.Add another 60.00 and you can get the same unit in colour.They also come with the gps puck and a dual beam transducer.To buy the same unit in a Lowrance you would pay almost double the price.So take a look you will be supprised at what you get for your money.Lowarance are no doubt good units but I think dollar for dollar Humminbird is a far better buy.
Just my 2 cents.
