Remote Wi-Fi Operation
Wi-Fi is a feature of a number of navigation displays. With the aid of a downloadable app, you view and control your display screen on an Apple or Android smartphone or tablet. This gives you a remote for radar, GPS, fish finder, etc. that you can hold in your hand while you move about the boat. The Furuno DRS4W 1st Watch dome antenna, for example, is a low-cost radar ($1,695) that uses Wi-Fi to display a radar picture wirelessly on an Apple iPhone or iPad.
