In low- or no-visibility conditions, few navigational instruments are as mission-critical as radar. Furuno's 4kW ultra-high-definition DRS4DL radar ($1,800) has an antenna — housed inside a tidy 36-inch radome — with a range of up to 36 nautical miles and a horizontal beam width of 5.2 degrees. The unit consumes just 23 watts when operating in transmit mode and 10 watts in standby mode, and it comes fitted with Furuno's convenient "pigtail" cabling, providing power to the antenna while delivering radar imagery to a networked NavNet TZtouch black-box processor or a TZtouch2 multifunction display.
