The Lowrance Mark 4 is a value minded no compromise fishfinder and chartplotter that features a high bright 3.5 inch backlit LED screen that is designed and proven as easy to read even under direct sunlight. This display features a unique trackback system where you can enhance any area of screen by 400% in order to examine the detailed sonar history and identify specific underwater fish and structures with ease. The sonar technology uses a dual 83/200 Khz frequency system with 2100 watts of peak to peak power and a maximum depth of 1,000 feet.
Included with the unit is a simple plug and play low profile tilt and swivel mount for adjustable viewing and the mount can be easily moved and re-mounted to a trolling motor. The controls on the unit are simple and intuitive and are designed for one hand which makes for easy operation even while moving.
Beyond fishfinding and chartplotting the Lowrance Mark 4 also includes a full GPS system which is ideal for those waterways that more twist and turns than one can remember and for those out in the ocean when suddenly the shoreline goes beyond your view or when on the ocean, a river, or lake and thick fog unexpectedly rolls in bringing visibility to near zero within minutes. In these instances the GPS and the backlit display will prove invaluable as the Lowrance Mark 4 safely navigates you home.
