Products with integrated precision reticle:
It is highly visible

and gives measurements in metres or feet (0.33m).
Measurement example:
A boat with a height of 10m is intersecting
your course. You read the value 20 from
the number scale of the reticle. The dis-
tance to be calculated is the actual size, 10
m in our example, divided by the read size,
20 m in our example, multiplied by 1000.
10 m / 20 = 0.5 x 1000 = 500 m. Thus, the
ship is 500 m away.
Formula to use the measurement scale:
Distance:
Actual size (e.g.10m)
Read size (e.g. 20m)
x 1000
or
Actual size:
Distance x read size
1000
1 nautical mile = 1.852km
