Enhanced accuracy with the Pulsar Stream Vision Ballistic App
Pulsar’s Stream Vision Ballistics App provides your Pulsar thermal riflescope with valuable trajectory data to enable accurate hold-over by way of an aiming point on the reticle.
Placing an accurate shot at various distances is a fundamental shooting skill that requires an understanding of projectile trajectory, target distance and the most difficult to calculate, cross wind. Inclination (height above or below Target) is another important consideration, while factors such as air temperature and humidity have a lesser effect. The slower the projectile moves, the steeper is its trajectory and holdover (or under) becomes more important.
For instance, shooting rabbits with a subsonic.22LR sighted-in for 50m, requires expediently higher holdover for longer distances. While the bullet has sufficient power to kill a rabbit at a considerably further distance, knowing where to aim is critical for success.
Introducing Pulsar Stream Vision Ballistic App.
Though this app can be used as a stand-alone ballistic calculator for use with any riflescope, its greatest benefit is when used with a Pulsar thermal riflescope. After setting up a ballistic profile for your rifle and ammunition, the information is saved into the thermal sight where it is used to move an aiming mark up and down the reticle with remarkable accuracy.
Pulsar thermal riflescopes with an inbuilt laser rangefinder, such as the Pulsar Trail LRF and Pulsar Thermion LRF, simply require ranging the target to indicate point-of-impact. This is by way of a small cross or line, that is clearly visible on the reticle. Ranging targets at different distances, as well as when shooting up or downhill, moves the aiming mark to the correct position.
Pulsar thermal riflescope not fitted with a laser rangefinder, such as the Pulsar Trail, Pulsar Thermion and Pulsar Talion, requires the use of an optical or thermal laser rangefinder. Once the target distance is known, it is dialed into the scope, which moves the aiming mark to the correct position on the reticle. Though not as quick or efficient as a LRF scope, it still works very well.
The how to
It’s not my intention to provide a step-by-step guide for setting up and using Stream Vision Ballistics in this article, but to make readers aware of the outstanding benefits that this free app offers.
There are How-To videos on the Advanced Optics website that explain set-up in detail.
This is a brief breakdown of the steps required to use the Pulsar Stream Vision Ballistic App.
- Ensure that your thermal optic has the latest Firmware installed. If not, you can do this via Stream Vision 2, (informative video available on Advanced Optics website).
- Download the Stream Vision Ballistics App from Google Play or Apple Store to your phone or tablet and open the App.
- Input the required information into the App, such as height of scope above barrel, ammunition type and velocity, zero distance etc. Save and name the profile.
- Turn on your Pulsar thermal riflescope, connect to your phone in the App. and download the ballistic profile to your riflescope.
- Select the named profile in your riflescope. You can store several profiles for different ammunition.
The accuracy of the information that you use when setting-up Stream Vision Ballistics is important for ensuring correct projectile trajectory. If you own or have access to a Ballistic Chronograph, this will provide definitive muzzle velocity. Another alternative is to use manufacturer’s ballistic information for factory ammunition. Bear in mind that these figures are based on a 24” barrel, so shorter barrels will develop less velocity which should be taken into consideration. I have seen figures of approximately 25fps – 50fps less per inch. To be honest, it is probably not going to make much difference on a centrefire at sensible shooting distance. Bear in mind that at longer ranges, slight crosswinds would have a greater effect on accuracy. Limit your maximum shooting distance to ensure a clean kill.
