Setting Up Jumpmaster on Your Garmin Watch
Jumpmaster is designed for experienced skydivers, particularly those in the military. It provides detailed information for speed of descent and altitude.
Jump Types
Jumpmaster allows users to set one of three types of jumps:
High Altitude-High Opening (HAHO)
High Altitude-Low Opening (HALO)
Static Jumps
Preparing for a Jump With the Jumpmaster Activity
Settings can be customized for each jump including the Desired Impact Point (DIP) and wind set up. As the altitude information is based on the Barometric Altimeter, calibrated before using Jumpmaster. Altitude data will update once per a second.
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.
Press
Start/Stop.Select Jumpmaster.
Some watches you will need to first select Activities.
Select a jump type.
Enter the jump information. The device calculates the HARP.
Select Go To HARP to start navigation to the HARP.
Press
Start/Stop.Select Jumpmaster.
Select a jump type.
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.
Select Auto to DIP to enable navigation to the DIP automatically after you jump.
Select Go To HARP to start navigation to the HARP.
Press
Start/Stop.Select Jumpmaster.
Select a jump type (Jump Types).
Select Wind.
Select Add.
Select an altitude.
Enter a wind speed in knots and select Done.
Enter a wind direction in degrees and select Done.
NOTE: The wind value is added to the list. Only wind values included in the list are used in calculations.
Repeat steps 5–7 for each available altitude.
Press
Start/Stop.Select Jumpmaster.
Select Static.
Select Wind.
Enter a wind speed in knots and select Done.
Enter a wind direction in degrees and select Done.
Press
Start/Stop.Select Jumpmaster.
Select a jump type.
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.
