Jumpmaster

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

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
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.

Complete one or more actions to enter your jump information:
• Select DIP to set a waypoint for the desired landing
location.
• Select Drop Alt to set the drop altitude AGL (in feet) when
the jumpmaster exits the aircraft.
• Select Open Alt to set the open altitude AGL (in feet)
when the jumpmaster opens the parachute.
• Select Forward Throw to set the horizontal distance
traveled (in meters) due to aircraft speed.
• Select Crs. to HARP to set the direction traveled (in
degrees) due to aircraft speed.
• Select Wind to set the wind speed (in knots) and direction
(in degrees).
• Select Constant to fine-tune some information for the
planned jump. Depending on the jump type, you can
select Percent Max., Safety Factor, K-Open, K-Freefall,
or K-Static and enter additional information

Enter a wind direction in degrees and select Done.

Constant Settings

Select Jumpmaster, select a jump type, and select Constant.
Percent Max.: Sets the jump range for all jump types. A setting
less than 100% decreases the drift distance to the DIP, and a
setting greater than 100% increases the drift distance. More
experienced jumpmasters may want to use smaller numbers,
and less experienced skydivers may want to use larger
numbers.
Safety Factor: Sets the margin of error for a jump (HAHO only).
Safety factors are usually integer values of two or greater,
and are determined by the jumpmaster based on
specifications for the jump.
K-Freefall: Sets the wind drag value for a parachute during
freefall, based on the parachute canopy rating (HALO only).
Each parachute should be labeled with a K value.
K-Open: Sets the wind drag value for an open parachute, based
on the parachute canopy rating (HAHO and HALO). Each
parachute should be labeled with a K value.
K-Static: Sets the wind drag value for a parachute during a
static jump, based on the parachute canopy rating (Static
only). Each parachute should be labeled with a K value.

Heart Rate Features

The Instinct device has a wrist-based heart rate monitor and is
also compatible with chest heart rate monitors (sold separately).
You can view heart rate data on the heart rate widget. If both
wrist-based heart rate and chest heart rate data are available,
your device uses the chest heart rate data.
