I'm in the market for a new camera. I have an old school fish scout right now, but the old thing is getting quite out dated. I spoke with Aqua vu and they will give me a $100 credit for my old scout towards a new unit. I was looking at the 715C. I could get that for $200. My other option which is a bit more pricier was the marcum 485c. Just seeing if the extra $150 is paying for a great product or name. I mainly fish lakes and sloughs in NESD. The deepest I've fished was 34 FOW. If you have any experience with either unit I have open ears, tell me why you think one is better than the other.
