By Walker

Walker 4020 Mk2 is a compact EM Speed Log for smaller vessels that 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. High-reliability sensors, flush fitting, fixed and retractable types housed in hull fittings suitable for various hull materials, such as aluminium alloy, steel, GRP and wood.
