Re: fish finder
i have a humminbird 947C at the console, and an Eagle (which is a lowrance) up front.
They are all really good man. my eagle is probably a 150 bucks for a comparable model today, and my humminbird is (hu hum) about $1600. If you buy anything that is $150 or over, you are going to be fine. There are some real cheapos out there, so i can only relate functionality to price. I would say spend $150 or more, stay with Humminbird, Lowrance or Eagle (which is a Lowrance anyway). Any other brands, just keep walking.
