able to estimate the distance to the trans-
mitter, a process called ranging. When
y ou are driving in y our v ehicle toward the
transmitter f rom a distance, the key question often
is, "when should I get out and start walking?" A
common mistake is getting out on foot too soon,
thinking you are near enough to walk. The
Medium
setting helps you avoid this mistake.
When the signal can be heard on Medium, you're
close enough to get out and search on foot.
Note: Other receiv ers have powerf ul Medium settings which tend to fool
y ou into thinking a transmitter is closer than it is. This high sensitivity is
good on Far, but on Medium, this is not a virtue. The Field Marshall is
intentionally designed with a weaker, and more precise Medium range.

The range setting is for use in all situations when the signal is too
weak to be heard on Medium.
Comparing the range of two receiv ers set on
cars in only second gear — winning means nothing because the gear ratios
are arbitrary. Only compare perf ormance of receivers with the ranges of
both receivers set to Far. To have a race, put them both in high gear.
