The i50 Depth instrument display reveals real-time water depth along with audible and visible alerts for shallow water. It also tracks maximum and minimum depth as well as the depth trend. With large digits and audible alarms for deep, anchor, and shallow water, this display works perfectly for sail boats, power boats, yachts, and RIBs. The i50 Depth instrument is engineered for easy viewing. Its high-contrast LCD, oversized digits, and red backlighting combine to deliver superior visibility under all conditions. i50 instruments also support local and group dimming control. This makes it easy to adjust the brightness of multiple Raymarine products all at once. Simple push button controls provide easy access to all its data displays. I50 series instruments are the perfect combination of powerful performance, easy operation and rugged reliability.
