MotionScope uses the Doppler effect to detect and highlight moving targets in different colors. This allows you to instantly distinguish between stationary objects and moving vessels, helping you avoid potential collisions.
The high rotation speed provides rapid, real-time updates on your display. This is particularly useful when navigating in busy harbors or tight channels where target movement changes quickly.
Yes, the GMR Fantom 18XW offers a maximum range of 48 nautical miles. This provides ample visibility for coastal cruising and offshore navigation.
Absolutely. The radar has a minimum range of 20 meters, making it effective for identifying nearby hazards, buoys, or other vessels in low-visibility conditions.
The unit is designed for intuitive operation and straightforward setup. However, as with any marine electronics installation, ensure your existing display is compatible and that you have the proper mounting space for the 18-inch dome.
The power save mode allows you to manage energy consumption during periods when you don't need full-time radar monitoring. It is an efficient way to preserve your vessel's battery life without sacrificing the unit's core capabilities when active.
