Collection: GPS - Chartplotters

Chartplotters in this lineup range from 10-inch multifunction displays up to a 24-inch nav-station screen, so the first question is how much helm space you have. Several models, including the B&G Zeus SR series and the Simrad NSS4 range, are sold without sonar, meaning you will add a transducer and black box later if you need depth. The Garmin GPSMAP 8610, 8612, and 8616 include GN+ cartography out of the box. The Simrad NSO evo3S is a display-only unit requiring a separate processor rather than a standalone install.

Each brand runs its own networking ecosystem. B&G caters primarily to sailors, Simrad to powerboat and sportfish crews, and Raymarine's Axiom 2 XL works well across both. SI-TEX is a practical option for boaters wanting solid GPS navigation without committing to a full multifunction suite. Before buying, check the mounting footprint against your helm space, confirm the unit networks with existing radar, autopilot, or instruments, and verify chart format compatibility for your cruising area.
