Garmin’s GNX 20 and 21 instruments allow trimmers, drivers and navigators to get all the information they want, when they want it, no matter what the conditions. Measuring 4in across, the glass-bonded, monochrome displays feature over 50 different vessel parameters, including depth, wind, speed, course over ground, distance to waypoint and other navigational data. The GNX 20 shows black digits against a white background; the 21 show white digits against black. You can also custom order the digits or backgrounds for either model in red, orange, green, blue or purple to further fine-tune your display. Underway, an auto-scroll function allows you see multiple performance parameter without ever having to take your hands off the helm. The screens draw just 350 mW during the day, 400 mW when backlit.
