well i do beleive i want to go with this unit . but was wondering if it showed thermecline. isn't that important to know in the summer months. and i hope i'm not wrong here. cant you lower your bait down and see it on your finder. i heard once you coulf watch a jig at so many feet on some of these. what about the 565 ????? i want that feature and the thermocline thing. i fiqured , if i can just find depth , thermocline , and could see my bait . it has to improve my catching numbers..
