Training with the Drill Log
The drill log feature is available only for pool swimming. You can use the drill log feature to manually record kick
sets, one-arm swimming, or any type of swimming that is not one of the four major strokes.
1 During your pool swim activity, press UP or DOWN to view the drill log screen.
2 Press BACK to start the drill timer.
3 After you complete a drill interval, press BACK.
The drill timer stops, but the activity timer continues to record the entire swim session.
4 Select a distance for the completed drill.
Distance increments are based on the pool size selected for the activity profile.
5 Select an option:
• To start another drill interval, press BACK.
• To start a swim interval, press UP or DOWN to return to the swim training screens.
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 12).
2 Enter the jump information (Entering Jump Information, page 13).
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. 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.
