Lowrance Mark-4 83/200 kHz

Despite its small size, the Mark-4 is equipped with a monochrome display that provides high-definition images in all weather conditions. The navigator supports Navionics mapping via a microSD memory card. The display allows you to view maps and the echo image at the same time thanks to the horizontal split screen function. The built-in GPS receiver allows you to accurately record the location of the ship on the map.

The Lowrance Mark-4 has memory for storing 3,000 waypoints, 100 routes (up to 100 points each) and 100 tracks (up to 10,000 points each). The unique TrackBackTM feature allows you to scroll through up to four pages of echo history for detailed analysis of targets and saving waypoints.
