I'm giving some serious consideration to buying the Humminbird PiranhaMAX 4 DI fish finder for my row boat and am wondering if anyone has or used one of them. It looks pretty nice and the price isn't too bad, $146. I'm looking to stick to my budget and am looking for reviews on this particular model. Here's a link to it:
