Walker 4020 is a new compact EM speed log for smaller vessels which require a \"Wheelmarked\" MED type approved system in a minimal
package reducing the size and number of sub-units required. This results in a smaller, lighter system which is simpler to install.
The 4020 design is based on the larger, proven and type approved, Walker 7070 Integrated Speed Log, Wind Data and Weather Data System.
The 4020 combines the electronics unit with the speed and distance indicator in one master unit which may be console or bracket mounted.
