Lowrance Mark 4 CHIRP Fishfinder

The Lowrance Mark 4 CHIRP Fishfinder is a fish finder and chart plotter all-in-one with a bright, LED backlit grayscale display and incredible CHIRP Sonar with DownScan Imaging technology to deliver you a clear, high definition view.

The Mark-4 CHIRP features the CHRIP Sonar technology to provide improved sensitivity, improved target resolution and superior noise rejection. This gives you a much clearer and easier to see target of game and bait fish, particularly when at greater depths. Even going at a faster speed on the boat, you will also be able to mark fish clearly and the highly accurate, built-in GPS antenna will produce a clear map all around you.

The Advanced Signal Processing (ASP) automatically adjusts for a clear view of fish, the structure and bottom detail and reduces the need for you to manually adjust these settings. TrackBack also lets you review recorded sonar history including structure, transitions or fish targets and then pinpoint the locations with a waypoint.

The Lowrance Mark 4 CHIRP Fishfinder features a brilliant, high-resolution, 4.3-inch, LED-backlit display and is available at an amazingly affordable price.
