Virtual Feedback models use electronic computation to estimate rudder position without a physical sensor - a good option for boats where mounting a rudder sensor is difficult or impractical. Physical rudder feedback generally provides slightly more accurate position data, while virtual feedback offers a simpler, cleaner installation.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need to purchase a drive unit separately?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eIt depends on which model you choose. The \"No Drive Unit\" variants include only the control head and feedback unit, so you would need a compatible drive unit separately. Other variants come bundled with a specific drive unit - such as an 18CI hydraulic pump or a Type S\/T mechanical dash drive - matched to common boat configurations. Check which drive type suits your steering system before ordering.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the SP-120C compatible with my existing GPS chartplotter?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes, in most cases. The SP-120C features NMEA-0183 connectivity for GPS input, which is the standard communication protocol used by the vast majority of marine GPS chartplotters and navigation electronics. This allows the autopilot to receive heading data from your GPS and maintain a precise course automatically.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan the SP-120C be used on both 12V and 24V electrical systems?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes. The SP-120C is designed to operate on both 12 and 24 Volt DC systems, making it compatible with a wide range of boats. Its low standby current draw of 0.5 amps at 12VDC also ensures it won't place significant strain on your battery bank when not actively steering.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat does the IPX6 waterproof rating mean for helm installation?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eIPX6 means the control head is protected against powerful water jets from any direction - essentially spray and splashing from heavy rain, waves, or helm wash. This makes it suitable for exposed helm stations on open powerboats.
