To access the Jumpmaster:
On the Setup Menu Page, highlight the
Jumpmaster icon, and press ENTER.
The Jumpmaster follows military guidelines for
calculating a jumpmaster’s high altitude release point
(HARP). The Jumpmaster can auto-detect when you

impact point (DIP) using the barometer and electronic
compass.
You can set the Jumpmaster to one of three types
of jumps, HAHO, HALO, or Static. The jump type
selected determines what additional setup information
is required. For all jump types, altitudes (drop or
opening) are measured in feet above ground level
(AGL).
An impact point (DIP) must be set for HAHO jumps.
This is a waypoint marked where you want to land.
The drop altitude of at least 1,000 feet must be
specified next. The Jumpmaster uses the drop altitude
as the opening altitude for HAHO jumps. Common
values for a drop altitude range from 12,000 to 24,000
feet AGL.
For HALO jumps, the required information is the
same as the HAHO jump type, plus an opening
altitude. This altitude may not be a larger value than
