Jumpmaster
WARNING
The jumpmaster feature is for use by experienced skydivers only. The jumpmaster feature should not be used
as a primary skydiving altimeter. Failure to input the appropriate jump related information can lead to serious
personal injury or death.
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
1 Select a jump type (Jump Types, page 4).
2 Enter the jump information (Entering Jump Information, page 5).
The device calculates the HARP.
3 Select GO TO 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, page 5).
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.
