Bullet Diameter: The bullet diameter measured in inches.
Input field.
NOTE: The diameter of the bullet may vary from the
common name of the round. For example, a 300 Win
Mag is actually .308 inches in diameter.
Bullet Length: The length of the bullet measured in inches.
Input field.
Bullet Weight: The bullet weight measured in grains. Input
field.
Drag Curve: The Applied Ballistics custom drag curve, or
the G1 or G7 standard projectile models. Input field.
NOTE: Most long range rifle bullets are closer to the G7
standard.
Profile Fields, Gun Properties
Muzzle Velocity: The speed of the bullet as it leaves the
muzzle. Input field.
NOTE: This field is required for accurate calculations
by the shooting solution. If you calibrate the muzzle
velocity, this field may be updated automatically for a
more accurate firing solution.
Output Units: The output units of measure. A milliradian
(mil) is 3.438 inches at 100 yards. A minute of angle
(MOA) is 1.047 inches at 100 yards.
Sight Height: The distance from the center axis of the rifle
barrel to the center axis of the scope. Input field.
TIP: You can easily determine this value by measuring
from the top of the bolt to the center of the windage
turret, and adding half of the diameter of the bolt.
SSF - Elevation: A linear multiplier that accounts for
vertical scaling. Not all rifle scopes track perfectly, so
the ballistics solution requires a correction to scale
according to a particular rifle scope. For example, if a
turret is moved 10 mil but the impact is 9 mil, the sight
scale is 0.9. Input field.
SSF - Windage: A linear multiplier that accounts for
horizontal scaling. Not all rifle scopes track perfectly,
so the ballistics solution requires a correction to scale
according to a particular rifle scope. For example, if a
turret is moved 10 mil but the impact is 9 mil, the sight
scale is 0.9. Input field.
Twist Rate: The distance it takes for the rifling of your
barrel to make one full rotation. Rifle twist is often
provided by the gun or barrel manufacturer. Input field.
Zero Height: An optional modification to impact elevation
at zero range. This is often used when adding a
suppressor or using a subsonic load. For example,
if you add a suppressor and your bullet impacts the
target 1 inch higher than expected, your Zero Height is
1 inch. You must set this to zero when you remove the
suppressor. Input field.
Zero Offset: An optional modification to impact windage
at zero range. This is often used when adding a
suppressor or using a subsonic load. For example,
if you add a suppressor and your bullet impacts the
target 1 inch to the left of the expected impact, your
Zero Offset is -1 inch. You must set this to zero when
you remove the suppressor. Input field.
Zero Range: The range at which the rifle was zeroed. Input
field.
Profile Fields, Gun Properties, Calibrate Muzzle Velocity
Range: The distance from the muzzle to the target. Input
field.
TIP: You should enter a value as close as possible
to the range suggested in the shooting solution. This
is the range where the bullet slows to Mach 1.2 and
begins to enter the transonic range.
True Drop: The actual distance the bullet falls while in
flight to the target, displayed in milliradians (mil) or
minute of angle (MOA). Input field.
Profile Fields, Gun Properties, Calibrate Drop Scale Factor
Range: The range from which you are shooting. Input field.
TIP: This range should be within 90% of the
recommended range suggested in the shooting
solution. Values that are less than 80% of the
recommended range will not provide a valid
adjustment.
True Drop: The actual distance the bullet falls when fired
at a specific range, displayed in milliradians (mil) or
minute of angle (MOA). Input field.
Training
Unified Training Status
When you use more than one Garmin device with your
Garmin Connect account, you can choose which device is
the primary data source for everyday use and for training
purposes.
From the Garmin Connect app, select
> Settings.
Primary Training Device: Sets the priority data source for
training metrics like your training status and load focus.
Primary Wearable: Sets the priority data source for daily
health metrics like steps and sleep. This should be the
watch you wear most often.
TIP: For the most accurate results, Garmin recommends
that you sync often with your Garmin Connect account.
Syncing Activities and Performance Measurements
You can sync activities and performance measurements
from other Garmin devices to your D2 Mach 1 watch
using your Garmin Connect account. This allows your
watch to more accurately reflect your training and fitness.
For example, you can record a ride with an Edge
®
bike
computer, and view your activity details and recovery time
on your D2 Mach 1 watch.
Sync your D2 Mach 1 watch and other Garmin devices
to your Garmin Connect account.
TIP: You can set a primary training device and primary
wearable in the Garmin Connect app (
).
