Garmin International Inc 03260 Manuale Utente

TIP: You can manually enter the temperature, or you can use

the temperature value from a connected tempe sensor.

WIND DIRECTION: The direction from which the wind is

coming. For example, a 9 O'CLOCK wind blows from your left

to right. Input field.

WIND SPEED 1: The wind speed used in the shooting solution.

Input field.

WIND SPEED 2: An optional, additional wind speed used in the

shooting solution. Input field.
TIP: You can use two wind speeds to calculate a windage

solution that contains a high and low value. The actual

windage to apply for the shot should fall in this range.

Target Fields
DIRECTION OF FIRE: The direction of fire, with north at 0° and

east at 90°. Input field.
NOTE: The DIRECTION OF FIRE is used only for calculating

the Coriolis effect. If shooting at a target less than 1,000

yards away, this input field is optional.

INCLINATION: The angle of inclination of the shot. A negative

value indicates a downhill shot. A positive values indicates an

uphill shot. The shooting solution multiplies the vertical

portion of the solution by the cosine of the inclination angle to

calculate the adjusted solution for an uphill or downhill shot.

Input field.

RANGE: The distance to the target, displayed in YDS (yards) or

M (meters). Input field.

SPEED: The speed of a moving target, display in mph or km/h.

A negative value indicates a target moving left. A positive

value indicates a target moving right. Input field.

Profile Fields, Bullet Properties
BALLISTIC COEFFICIENT: The manufacturer's ballistic

coefficient for your bullet. Input field.
TIP: When you use one of the Applied Ballistics custom drag

curves, the ballistic coefficient will display a value of 1.000.

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, 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
HORIZONTAL SIGHT SCALE FACTOR: 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 MILS but the impact is 9 MILS, the sight

scale is 0.9. Input field.

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. MIL (milliradian)

is 3.438 inches at 100 yards. MOA (minute of angle) 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.

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.

VERTICAL SIGHT SCALE FACTOR: 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 MILS but the impact is 9 MILS, the sight

scale is 0.9. 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
ENTER 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.

ENTER TRUE DROP: The drop in MIL or MOA at the target.

Input field.

Profile Fields, Gun Properties, Calibrate Drop Scale Factor
ENTER 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.

ENTER TRUE DROP: The drop in MIL or MOA of the bullet

when fired at range. Input field.
