What Is Lowrance Mark 4?

The Mark 4 is a top-of-the-line fish finder GPS that combines the convenience of a unit with a 4.3-inch widescreen color display with advanced features such as chart plotting and sonar.

This allows you to see your bottom contours at higher resolution, so you can find those fish fast!

The fish finder and chart plotter can work together to give you a complete picture of what’s happening on the water right now, including details such as fish location, weather information, and other helpful features.

How Does it Work?

With the Lawrance Mark 4 combo base, you can easily bring up your sonar to 200 watts via a quick-release transducer for greater efficiency and less downtime.

The fishfinder system is compatible with high-speed DGPS and GLONASS satellites, which allows you to get super-fast time updates for faster GPS positioning.

You can also update waypoints and markers on the go, so you don’t ever have to stop fishing.

Negative Reactions

There have been instances where the sonar has not been detected easily at first, but many users say that this was only a minor problem and eventually went away.

If you have experienced any issues with your fish finder in the past, you should note that this unit allows for easy troubleshooting by using markers to track down and fix any problems you have.

As with most fish finders, the screen can get scratched and damaged over time. If this does happen, however, all of the Mark 4’s components are easily replaceable, so replacing the parts on your unit is an easy fix to avoid having to purchase a new one.
