Offering advanced fishfinding and chartplotting performance in a compact and affordable unit, theLowrance Mark-4 Fishfinder/Chartplotter has everything serious, budget-conscious anglers need - and more. Easy-to-use menus and fast installation are just two of the ways the Mark-4 surpasses the competition.

The Mark-4 delivers impressive detail on its 3.5in/8.9cm grayscale display that virtually expands to 4X its size with the integrated TrackBack feature. TrackBack gives you greater control of your time on the water. By simply moving the cursor back through sonar-display history, you can quickly identify baitfish, game-fish or structure and save a waypoint. New, brighter LED backlighting also furnishes even better viewing quality in direct sunlight and low light conditions.

A low-profile, high-speed, transom-mount, 83/200 kHz Skimmer transducer with built-in temp sensor offers a maximum of 2100W PTP (262W RMS) sonar output to a depth of up to 1,000ft, and its internal, accurate precision GPS provides superior navigational guidance. Built-in memory also allows for up to 3,000 waypoints, 100 routes/100 waypoints per route and 100 retraceable plot trails/up to 10,000 points per trail.

The Mark-4 is also easy-to-install with a quick-release mounting system, featuring a tilt and swivel bracket for plug-and-play use. Or, it can be flush-mounted using the accessory mounting-kit option. For fast and smooth one-hand operation, the Mark-4 design includes easy-to-use page and menu controls. The simplified menus makes it easy to learn and use right out of the box.

The Lowrance Mark-4 Fishfinder/Chartplotter even comes preloaded with a detailed basemap, and is compatible with Fishing Hotspots Pro, Navionics Gold and premium charting upgrades through the built-in, waterproof MicroSD card slot.
