Because the SporTrak attains information it needs
from satellites orbiting the earth, the antenna needs to
have a relatively unobstructed view of the sky. This allows the
SporTrak to choose from all satellites currently available.
If the view of the sky is poor due to large cliffs or buildings, heavy
foliage or other obstructions, the satellite signals can be blocked and
the receiver may take longer to compute a position fix.
You can observe the signal strength and the satellites being used on the
Satellite Status screen (described in the next
section).
Holding the SporTrak. The receiver is
designed to fit comfortably in your hand.
Hold the SporTrak in the palm of your hand
with the antenna pointing towards the sky.
