## 1. Overview

### 1.1 Vector 21 Rangefinder
ACE3 adds a realistic depiction of the Vector 21 rangefinder to the game. Unlike other rangefinders, it doesn't just magically show you the range to your target, but in exchange allows you to do alot of things with it that the other choices in Arma do not offer. The Vector's functions include, but are not limited to:

- Distance to a target
- Azimuth to a target
- Horizontal and vertical distance to a target
- Distance between 2 targets
- Angle between 2 targets
- Switching between feet and meters
- Switching between degrees and mils
...

## 2. Usage

The Vector is controlled with 2 keys: the azimuth key and the range key; <kbd>Tab</kbd> and <kbd>R</kbd> and is brought up like any other binoculars.

#### 2.1 Slope distance

- Press and hold <kbd>R</kbd> until the red pointing circle appears. Sight the circle on the object and release the key.

#### 2.2 Azimuth

- Press and hold the <kbd>Tab&nbsp;↹</kbd> until the azimuth is displayed.

#### 2.3 Slope distance and Azimuth

- Press and hold both <kbd>R</kbd> and <kbd>Tab&nbsp;↹</kbd> until the red pointing circle appears.
- Sight the circle on the object and release both keys.

#### 2.4 Horizontal distance and height difference

- Tap <kbd>R</kbd> once then press and hold it until the red pointing circle appears.
- Sight the circle on the object and release the key.

#### 2.5 Azimuth and Inclination

- Tap <kbd>Tab&nbsp;↹</kbd> once then press and hold it until the azimuth and inclination is displayed.

#### 2.6 Distance between two points

- Press and hold <kbd>R</kbd> until the red pointing circle appears.
- Sight the circle on the first object and tap <kbd>Tab&nbsp;↹</kbd> while further holding <kbd>R</kbd>. The first measurement is confirmed ("1-P" = first point).
- Sight the second object and release <kbd>R</kbd>.

#### 2.7 Horizontal and vertical distance between two points
<img src="{{ site.baseurl }}/img/wiki/user/vector7.webp" width="500" height="160" alt="Measuring Horizontal and vertical distance between two points"/>

- Tap <kbd>R</kbd> once then press and hold it until the red pointing circle appears.
- Sight the circle on the object and tap <kbd>Tab&nbsp;↹</kbd> once. The first measurement is confirmed ("1-P" = first point).
- Sight the second object and release <kbd>R</kbd>.

#### 2.8 Horizontal distance and azimuth between two points
<img src="{{ site.baseurl }}/img/wiki/user/vector8.webp" width="500" height="160" alt="Measuring Horizontal distance and azimuth between two points"/>

- Press and hold <kbd>Tab&nbsp;↹</kbd> until the azimuth appears.
- Sight the circle on the first object and tap <kbd>R</kbd> while further holding <kbd>Tab&nbsp;↹</kbd>. The first measurement is confirmed ("1-P" = first point).
- Sight the second object and release <kbd>Tab&nbsp;↹</kbd>.

#### 2.9 Fall of shot
<img src="{{ site.baseurl }}/img/wiki/user/vector9.webp" width="500" height="160" alt="Measuring Fall of shot"/>

- Tap <kbd>Tab&nbsp;↹</kbd> once then press and hold it until the azimuth appears.
- Sight the circle on the object and tap <kbd>R</kbd> while further holding <kbd>Tab&nbsp;↹</kbd>. The first measurement is confirmed ("1-P" = first point).
- Sight the Fall of shot and release <kbd>Tab&nbsp;↹</kbd>. The left digits display the left (`L`)/right (`r`) correction value in meter and the right digits display the longer (`A` = add)/shorter (`d` = drop) correction value in meter. If <kbd>R</kbd> is tapped the height correction values will be displayed (`UP` and `dn`).

#### 2.10 Setting the measurement units (degrees/mils &amp; meters/feet)

- Tap <kbd>Tab&nbsp;↹</kbd> five times fast. "Unit SEtt" appears briefly.
- Press <kbd>R</kbd> until the desired units are displayed.
- Tap <kbd>Tab&nbsp;↹</kbd> five times fast to save the selection.
