Jumpmaster
The jumpmaster feature is designed for experienced skydivers,
particularly those in the military.
The jumpmaster feature follows military guidelines for
calculating the high altitude release point (HARP). The device
detects automatically when you have jumped to begin
navigating toward the desired impact point (DIP) using the
barometer and electronic compass.
Planning a Jump
WARNING
Jumpmaster is for use by experienced skydivers only.
Jumpmaster should not be used as a primary skydiving
altimeter. Failure to input the appropriate jump related
information into Jumpmaster can lead to serious personal injury
or death.
1
Select a jump type (Jump Types).
2
Enter the jump information (Entering Jump Information).
The device calculates the HARP.
3
Select GOTO HARP to start navigation to the HARP.
Jump Types
The jumpmaster feature allows you to set the jump type to one
of three types: HAHO, HALO, or Static. The jump type selected
determines what additional setup information is required
(Entering Jump Information). For all jump types, drop altitudes
and opening altitudes are measured in feet above ground level
(AGL).
HAHO: High Altitude High Opening. The jumpmaster jumps
from a very high altitude and opens the parachute at a high
altitude. You must set a DIP and a drop altitude of at least
1,000 feet. The drop altitude is assumed to be the same as
the opening altitude. Common values for a drop altitude
range from 12,000 to 24,000 feet AGL.
HALO: High Altitude Low Opening. The jumpmaster jumps from
a very high altitude and opens the parachute at a low
altitude. The required information is the same as the HAHO
jump type, plus an opening altitude. The opening altitude
must not be greater than the drop altitude. Common values
for an opening altitude range from 2,000 to 6,000 feet AGL.
Static: The wind speed and direction are assumed to be
constant for the duration of the jump. The drop altitude must
be at least 1,000 feet.
