Dunno, Denise. I ran into the same thing at a WM store.
After researching it (you can find the thread in Gear & Maintenance if you look for it), I
was going to go with a current-year Lowrance. Seemed to offer more bang for the buck. But here's the odd thing: The previous year's
Garmin, which actually had lower screen resolution than the Lowrance,
appeared to have a more clear, readable display. And I liked the "feel" of the unit better. Felt more substantial to me. In the end, going by "best price from a
reputable on-line reseller": I was able to get the
Garmin 498C with built-in cartography, in-hull sonar transducer and external antenna, shipping and all, for more than $100 less than the approximate equivalent Lowrance unit, by the time I added cartography to the Lowrance.
So I ended-up with a
Garmin, after all.
