Swim Terminology
Length: One trip down the pool.
Interval: One or more consecutive lengths. A new interval starts
after a rest.
Stroke: A stroke is counted every time your arm wearing the
device completes a full cycle.
Swolf: Your swolf score is the sum of the time for one pool
length and the number of strokes for that length. For
example, 30 seconds plus 15 strokes equals a swolf score of
45. For open water swimming, swolf is calculated over 25
meters. Swolf is a measurement of swimming efficiency and,
like golf, a lower score is better.
Stroke Types
Stroke type identification is available only for pool swimming.
Your stroke type is identified at the end of a length. Stroke types
appear when you are viewing interval history. You can also
select stroke type as a custom data field (Customizing the Data
Screens, page 18).

Indoor Activities
The fēnix Chronos device can be used for training indoors, such
as running on an indoor track or using a stationary bike. GPS is
turned off for indoor activities.
When running or walking with GPS turned off, speed, distance,
and cadence are calculated using the accelerometer in the
device. The accelerometer is self-calibrating. The accuracy of
the speed, distance, and cadence data improves after a few
outdoor runs or walks using GPS.
4 Activities
TIP: Holding the handrails of the treadmill reduces accuracy.
You can use an optional foot pod to record pace, distance, and
cadence.
When cycling with GPS turned off, speed and distance are not
available unless you have an optional sensor that sends speed
and distance data to the device (such as a speed or cadence
sensor).

Jumpmaster
The jumpmaster feature is designed for experienced skydivers,
particularly those in the military.
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
WARNING
Jumpmaster is for use by experienced skydivers only.
Jumpmaster should not be used as a primary skydiving
altimeter. Failure to input the appropriate jump related
information into Jumpmaster can lead to serious personal injury
or death.

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 6). 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.

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.

Fitness Goals
Knowing your heart rate zones can help you measure and
improve your fitness by understanding and applying these
principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve
cardiovascular capacity and strength.
• Knowing your heart rate zones can prevent you from
overtraining and can decrease your risk of injury.
If you know your maximum heart rate, you can use the table
(Heart Rate Zone Calculations, page 7) to determine the best
heart rate zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the
calculators available on the Internet. Some gyms and health
centers can provide a test that measures maximum heart rate.
The default maximum heart rate is 220 minus your age.
About Heart Rate Zones
Many athletes use heart rate zones to measure and increase
their cardiovascular strength and improve their level of fitness. A
heart rate zone is a set range of heartbeats per minute. The five
commonly accepted heart rate zones are numbered from 1 to 5
according to increasing intensity. Generally, heart rate zones are
calculated based on percentages of your maximum heart rate.
Setting Your Heart Rate Zones
The device uses your user profile information from the initial
setup to determine your default heart rate zones. The device
has separate heart rate zones for running, cycling, and
swimming. For the most accurate calorie data during your
activity, set your maximum heart rate. You can also set each
heart rate zone and enter your resting heart rate manually. You
can manually adjust your zones on the device or using your
Garmin Connect account.
