Going to buy one or the other in the next week or so and was looking for some expert advise. The 998 is some cheaper but I've always had lowrance finders. I'm sure they're both good but would like to hear from people that already have experience with them. Does the 998 just have one transducer where the HDS 8 needs two and do both units have internal gps or do they need external antenna? Not looking for a bashing just your experiences and preference for one of these units.
