impdog; this is a 570 humminbird which is a newer version of the older 565 you are looking for. My friend has one and the only thing that is different is that it has something called switch fire which is something new that humminbird came up with. Now don't get this mixed up with the 570 down scan because both has the same 570 number. Check it out at ebay. Here is the site hope it will help you.
