Best Color finder or Sonar for under $500.00

[Gotta Bite]

I am thinking about upgrading from my B&W Hummingbird 565 to something in color and is high def. I am not sure if this can be found for under $500.00 but just looking to see whats avaialble and what alot of the budget minded are using. GPS would be nice but from what I heard and read having both on the same unit is not good since it makes the screen smaller and if one goes then they are both no good. I can get away with using my hand held for another year. That purchase may come in 2013.

I would recommend a sonar/ GPS combo just because it is easier to install system upgrades. The sonar only units do not have a SD slot and you have to buy a special computer cable for upgrade downloads. The cost is about the same if you add the cost of the download cable. I bought a Humminbird 778 plus download cables plus adapter for USB port and ended up with more expense than just getting the 788 combo unit.

Looked into it and thought about it a little more. I'd prefer two separate units for a couple of reasons. Think I'll get the Garmin GPS this year and a Furuno fish finder the following year. Thanks for your response.
