698ci HD SIAlthough 600 Series units are compact, they are incredibly large on feature sets and functionality. From inception, the 600 Series was designed to meet the needs of anglers who want all the pro features of larger units but in a sleek, unobtrusive footprint with medium-size, easy-to-read screen. Whether gimbal mounted in the fore or aft of your boat or flush-mounted in the dash, the 600 Series brings anglers world-class fish-finding without having to compromise space for other instrumentation or fishable space.
