Gimbaled mounts improve performance, as a radome heeled to an angle of 15 degrees or more will suffer decreased range and effectiveness. Modern radars are becoming ever more compact and energy-efficient. Multi-level quantization is superior, but requires more processing power, hence is more expensive. LCDs, meanwhile, can't be beat for price and energy-efficiency, but their resolution is lower. This allows a target's course to be plotted as a trail on screen and is a great tool for avoiding collisions with other vessels.
Plots can be continuous or corrected at time intervals determined by the user.
An excellent safety feature that sounds an alarm when a target is detected anywhere around the boat, or in specific user-determined sectors. Especially useful for power-conscious cruisers. The radar set remains operational, but the screen is shut down to conserve energy and reduce consumption by 30 percent or more. With guard zones activated, an alarm will still sound if a target is acquired, and the screen can be activated at the touch of a button. These features allow you to determine and display the range and bearing of a given target on screen.
