I'm thinking about purchasing a fishfinder for my parents boat. I've narrowed it down (for cost reasons) to either the Garmin 100, Garmin 100Blue, or the Humminbird Piranha 5. Not sure if I really need the upgrad to the Blue model, as most of the fishing we do is in <200 ft of water.
Anyone have any suggestions? Ideally, I'd love to be around $100, but I'm willing to head up to around $150. Do the Garmin models come with the transducer? I haven't seen a straight answer to this question anywhere.
