I’m looking at the Lowrance HDS-5 and the Garmin 546s to use while guiding in AK this summer. I like that the Garmin has the preloaded Bluechart G2 maps and that the Lowrance has the structure scan. Other than those differences, what should I look at? Both will cost around $520-540 and come with 50/200Hz transom mount transducers, internal GPS antennas and a 5" screen.
If I were to go the Lowrance HDS-5 route, what chart software is recommended?
