Measuring Wind - Kestrel 5700 Instruction Manual

MEASURING WIND

An accurate crosswind measurement requires that the
Kestrel "know" both the direction of re and the wind
direction and strength. You may use the Kestrel's built-in
compass and wind measuring and averaging features to
capture these values:
CAPTURING THE DIRECTION OF FIRE:
» Select Tgt to enter the Target menu, scroll down and
select DoF, then scroll down and select Capture.
» Follow the on-screen instructions:
» While holding the Kestrel vertical, point the back of the
unit directly towards the target and select Capture.
» DoF will automatically be populated in the Target
menu.

CAPTURING THE WIND INPUTS:
» In the Target menu, scroll down and select WD,
WS1, or WS2.
» Scroll down and select Capture.
» Follow the on-screen instructions:
» While holding the Kestrel vertical, point the
back of the unit directly into the wind and
select Capture.
» Continue to point the Kestrel into the wind
for at least 5 seconds to capture a rolling 5
second average and peak value of the winds.
Select End Capture

WD, WS1, WS2 will automatically be
populated in the Target menu.
Note! Selecting Wind in the Ballistics Menu jumps directly to the
WD, WS1, & WS2 entries in the Target Menu.
Note! For maximum accuracy of compass readings when
capturing DoF and Wind, the Kestrel must be held as vertically
as possible – be careful not to tilt it away from you while taking
readings.
Note! Any time you are using the Kestrel to calculate an elevation
hold a direction of re plus wind direction and speeds must be
input. These inputs contribute to an accurate elevation solution.
