BL –

 Bullet Length is the length of the bullet measured in 

inches or millimeters. Automatically calculated from bullet 
weight. May be overriden if actual bullet length is known.  

ZR – 

Zero Range is the distance from the muzzle to the 

target at which the rifle was zeroed.  

BH – 

Bore Hight (Scope Height) is the distance from the 

center axis of the rifle barrel to the center axis of the 
scope.  This can be measured from the top of the bolt to 
the middle of the windage turret plus half the diameter of 
the bolt.

ZH –

Zero Height is a modification to impact elevation at 

zero range, often used when adding a suppressor or using 
a subsonic load.  (Not available in Sportsman models)

ZO – 

Zero Offset is is a modification to impact windage at 

zero range, often used when adding a suppressor or using 
a subsonic load.  (Not available in Sportsman models)

RT – 

Rifle Twist is the distance it takes for the rifling of your 

barrel to make one full rotation.  RT is often provided by 
the gun or barrel manufacturer.  It an also be measured 
by marking a tight fitting cleaning rod and measuring the 
insertion distance required to make one full rotation.  

RTd –

 Rifle Twist Direction is the rotational direction of the 

rifle twist.  A right hand twist (most common) is clockwise 
from behind the rifle.  

Eunit – 

Elevation Unit is the unit of measure used in a 

scope and reticle for elevation, either TMOA, SMOA, or 
Mil.

Eclck –

 Elevation Clicks is a user settable ratio of 

number of clicks of the elevation turret per TMOA, 
SMOA, or Mil.

Wunit –

 Windage Unit is the unit of measure used in 

a scope and reticle for windage, either TMOA, SMOA, 
or Mil.

Wclck – 

Windage Clicks is a user settable ratio of 

number of clicks of the windage turret per TMOA, 
SMOA, or Mil.

DSF – 

Drop Scale Factor is a truing value of the ballistic 

coefficient applied at transonic and subsonic speeds. 
(Not available in Sportsman models) 

TMOA – 

True Minute Of Angle is a measure of one 

actual minute of angle.  1 TMOA = 1.047” at 100 yards.  
Most MOA scopes are TMOA.

SMOA – 

Shooters Minute Of Angle is a simplified 

approximation of one minute of angle where 1 SMOA = 
1” at 100 yards.

Mil – 

Milliradian is a measure of angle using the USMC 

definition of 6283 mils = 1 circle, or 1 mil = 3.438 MOA.

CLIK –

 Click is the value of each click of the turret where 

the user selects the number of  clicks equal one TMOA, 
SMOA, or Mil, based on the turrets of their scope.

Update –

Setting Update to Yes inputs live 

measurements for temperature, pressure, and relative 
humidity into the ballistic solver. Selecting No for 
Update captures current environmental inputs and 
makes them user editable.

Lat – 

Latitude.  Can be found on a map or internet 

search for your area . 

Temp – 

Ambient Temperature is the temperature 

measured at the external temperature sensor.

SP – 

Station Pressure (Absolute Pressure) is the pressure 

exerted by the earth’s atmosphere at any given point. 

RH – 

Relative Humidity is the amount of moisture 

currently held by the air as a percentage of the total 
possible moisture that the air could hold.

Dalt - 

Density Altitude is the altitude at which the 

density of the theoretical standard atmospheric 
conditions (ISA) would match the actual local air density.

SpnDft – 

Spin Drift is a correction for lateral drift caused 

by the change to the bullets axis of rotation as it follows 
the arc of its trajectory.  (Not available in Sportsman 
models)

Wcap – 

Wind Capture  toggles between applying the 

windage correction to just the currently selected target 
or to all targets. 

Range Card is available on Elite Model only.
Range –

 Range is the distance to target

Elv –

 Elevation is the vertical correction needed to hit a 

target at a given range.

Wnd1 – 

Windage 1 is the horizontal correction needed to 

hit a target at a given range and 

average

 measured wind 

speed.

Wnd2 –

 Windage 2 is the horizontal correction needed 

to hit a target at a given range and 

maximum

 measured 

wind speed.

Lead –

 Lead is the horizontal correction needed to hit a 

target moving left or right at a given speed.

RemV –

 Remaining Velocity is the amount of a bullet’s 

initial velocity retained at a given distance.

RemE – 

Remaining Energy is the amount of a bullets initial 

energy retained at a given distance.

Rtrns –

 Transonic Range is the distance traveled by the 

bullet at which it slows to transonic speed (Mach 1.2).
