    Don Barrow Map Magnifiers

    Moulded in black PVC with a holding handle to locate in position on the map. All models have a milled internal groove to accept any of the Don Barrow Graticule Baseplates. The 'standard B01 supply' 1:50,000 Baseplate simply clips into the lower groove, to provide a printed Graticule which enables you to either plot Map References or measure distances on the map, see below for all other Scales and LED Options. All Pro-models are fitted with a Superior Quality 113mm dia x 1.5 +/- magnification (50+/-% larger) Crystal Glass Plano Convex Lens. The various models have different switching and bulb fitments. For replacement Bulb, you now have a choice of either 5 Watt Soft White LED or 5 Watt Red LED Bulb or the universally available cheap to replace 5 Watt Festoon Bulb, all available from my DB Spares page. The only Map Magnifiers with interchangeable Graticule Baseplates 1:25,000, 1:50,000, 1:100,000, 1:150,000, 1:200,000, Magic Eye & Distance Training Scales

    Map magnifiers are optical devices designed to enlarge and enhance the details of a map for easier reading and navigation. These tools are essential for rally navigators and co drivers who rely on accurate interpretation of  maps for competitive driving. Map magnifiers feature a crystal clear planar lens and internal illumination to magnify the small print, symbols, and landmarks on a map, making them easier to see and interpret. With their compact and portable design, map magnifiers or often called poti or poties are easy to use and use and an essential navigator accessory.

    Tips on using
    Don Barrow Light Map Magnifiers

     

    • Always switch on at least 20 Minutes before use, this allows the lens to warm up and reduce any condensation that may occur
    • Don't be tempted to cut a hole in the side of the Magnifier body, this let's the light shine out directly into your drivers face
    • Plotting Map References, looking through the Lens, set up the Romer on the exact spot, affix your eyes through the Romer onto the Map
    • Tilt the Map Magnifier and with your eyes still affixed on the exact spot, mark your Map, this needs practise to perfect
    • Always make sure you have the correct Baseplates to suit the Maps you are using
    • Remove the protective film from all new Baseplates
    • Use the divisions on the Reflector Scale to measure short distances - see below
    • 0.05 or 1/20th of a Mile on 1:25,000 Maps
    • 0.1 or 1/10th of a Mile on 1:50,000 Maps
    • 0.3 or 3/10ths of a Klm on 1:100,000 IGN Maps
    • 0.5 or 5/10ths of a kLm on 1:150,000 Maps
    • 0.6 or 6/10ths of a Klm on 1:200,000 Maps
    • Replace the flex after every 20 Rallies, the inner wires tend to snap inside the rubber grommet
    • Spare Bulbs are always essential, they never blow when you carry spares!
