Tips on using a DB Map Magnifier ·
Always switch on at least
20 Minutes before use, this allows the lens to de-mist if condensation has
occurred · 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 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 !
