A day will come, sooner than you think, when hard-wired marine electronics network connections are obsolete. In fact, the wireless revolution for marine electronics has already begun. That realization hit me a couple of years ago after experiencing Furuno’s DRS4W 1st Watch 24-nautical-mile radar, the first radar to dispense with a cable connecting display and controls. The 19-inch-diameter 4 kW radar dome uses Wi-Fi, and it doesn’t even need a multifunction display. The DRS4W wirelessly displays radar returns on a smartphone or tablet as shown above.
