Walker 4020 Mk2 is a 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 combines the electronics unit with the speed and distance indicator in one master unit which may be console or bracket mounted.
