## 1. Overview
|
||
|
||
### 1.1 AtragMx from Horus Vision
|
||
|
||
Horus ATragMX software considers atmospheric conditions, gun data, ammunition, range, speed and muzzle velocity to calculate precise aiming solutions with "come-up" results – and even accounts for Coriolis and spin drift effects. ATragMX, loaded on a handheld computer made by TDS Recon, is easy to use and lightning-fast. The Recon meets the rigorous MIL-STD-810F military standard for drops, vibration, humidity, altitude and extreme temperatures.
|
||

|
||
- *Check the new `Muzzle Velocity` in the `Gun` column.*
|
||
- Update the `Target` column (the [wind arrow]({{ site.baseurl }}/wiki/feature/weather.html) will also help). [[1]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=16) [[2]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=30) [[3]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=32) [[4]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=33)
|
||
- *The latitude for all common maps can be found in the [ACE3 Github]({{ site.ace.githubUrl }}/blob/master/addons/common/functions/fnc_getMapData.sqf).*
|
||
- Apply the vertical and horizontal elevations on the [scope]({{ site.baseurl }}/wiki/feature/scopes.html).
|
||
- Control the breath and press.
|
||
|
||
### 3.3 Example with Truing tool
|
||
|
||
**Start of the mission:**
|
||
|
||
- Select `Drag Coef Table` in the `Options` menu. [[Manual]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=14)
|
||
- Add the `ZR` and the `C1` (`Gun` column) in the table and `Done`.
|
||
|
||
**In position:**
|
||
|
||
- Open the `Truing Drop` in the `Options` menu. [[Manual]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=23)
|
||
- Add the actual `Target Range` in the `SUPER` column and `Calc`.
|
||
- Add the same `Target Range` in the `SUB` column and `Calc`.
|
||
- Apply the actual scope elevation in the `Drop` field and `Calc`.
|
||
- `Accept` the new `C1`, `Gun` column and `Elev` are updated.

|
||
|
||
<img src="{{ site.baseurl }}/img/wiki/feature/atragmx2.png" width="1127" height="600" alt="Calculation" />
|
||
|
||
- If a new `Target Range` is applied in the `Target` column, select `Drag Coef Table` in the `Options` menu and `Done`.
|
||
- The ballistic coefficient `C1` and the elevation `Elev` will be recalculated.

|
||
|
||
### 3.4 Example with overwritten zero distance
|
||
|
||
- The `Default zero distance` can be overwritten with the [Scopes module]({{ site.baseurl }}/wiki/feature/scopes.html) or the [Settings Framework]({{ site.baseurl }}/wiki/framework/settings-framework.html).
|
||
- In this case, the [Range Card]({{ site.baseurl }}/wiki/feature/rangecard.html) will be automatically updated, NOT the AtragMx.
|
||
- Open the AtragMx and the `Atmsphr` column, select `Default` and `Done`. [[Manual]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=15)

|
||
|
||
### 3.5 Example with `Add New Gun` in `GunList`
|
||
|
||
- Open the [Range Card]({{ site.baseurl }}/wiki/feature/rangecard.html) and check the cartridge, the bullet diameter, the bullet weight and the muzzle velocities.
|
||
- Open the AtragMx and the `Atmsphr` column, select `Default` and `Done`. [[Manual]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=15)
|
||
- Select `Add New Gun` in the `GunList`. [[Manual]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=25)
|
||
- Add a `New Gun Name` and `Open Gun`.
|
||
- Select `E` (English unit) at the top right. [[Manual]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=10)
|
||
- Open the `Gun` column, check and update the `Bullet Weight (grains)`, the `Bullet Diam (inches)` and `Done`.
|
||
- Select `M` (Metric unit) at the top right.
|
||
- Open the `Muz Vel Table` in the `Options` menu or click on `MV` in the `Gun` column.
|
||
- Edit manually the `Muzzle Velocity Table` according with the [Range Card]({{ site.baseurl }}/wiki/feature/rangecard.html) and `Done`. [[Manual]](https://horusvision.com/download/manual_Horus_ATrag-v385.pdf#page=22)
|
||
- The `C1 coefficient` of the bullet can be found with the Eden Editor `Config Viewer`:
|
||
|
||
> configfile >> "CfgAmmo" >> "Range card cartridge" >> "ACE_ballisticCoefficients"
|
||
|
||
> configfile >> "CfgAmmo" >> "Range card cartridge" >> "ACE_dragModel"
|
||
|
||
- *The AtragMx accepts only **G1 ballistic coefficient**.*
|
||
- *G7 ballistic coefficient can be converted, for example, with the online [JBM Ballistics Calculators](http://www.jbmballistics.com/cgi-bin/jbmgf-5.1.cgi)*.
|
||
- Optionally, `Save Gun` and `Done` in the `GunList`.
|
||
|
||
|
||
> Note: The ballistic coefficient can be calculated by using the [360 Degree Training Course mission](https://forums.bistudio.com/forums/topic/171228-sp-360-degree-training-course/) as a chronograph at different distances and [JBM Ballistics Calculators](http://www.jbmballistics.com/cgi-bin/jbmbcv-5.1.cgi) for example, an another ballistic software at your own convenience, or the [AtragMx Truing Tool](#33-example-with-truing-tool).
