Breaking Down the Features of Raymarine Instru., Speed, i50, Display Only

The Raymarine Instru., Speed, i50, Display Only is a focused instrument, designed to provide critical speed and temperature information with clarity and precision. Its core function is to display current speed, maximum speed, average speed, and velocity made good (VMG) when integrated with a heading source. The display itself is a 3.6-inch segmented LCD, which offers excellent readability under various lighting conditions, including bright sunlight. Its physical dimensions are 4.3 inches wide by 4.5 inches high, making it a reasonably compact unit that can fit into most existing instrument panels without requiring significant modification.

A key specification is its SeaTalk interface, which is Raymarine’s proprietary marine networking system.
