I was looking into buying a new Humminbird and I'm not sure which unit I need. I was looking at the 898c SI and the 998C SI. I'm not an expert at these but is there a very big difference between the two. I noticed that the 998c SI is and inch larger than the 898. When I do buy one is there any accessories that I need to buy(Navionics card, memory card, pc cable, etc.)? Also I have a Alumacraft V165 and without a jackplate, will that be a problem when I install the transducer? I was looking for a ram mount also and not sure which one would be the best. So I'm still trying to get more information before I buy one so anything at all would be great.
Thanks.
