        How to Use the Stream Vision™ Ballistic Calculator

        By bmatheus  

        The Ballistic Calculator helps you determine exact ballistics for accurate shooting. Set your parameters for the bullet and cartridge and current weather conditions for a precision shot, even at long distances. The Ballistic Calculator is compatible with any riflescope, including thermal and digital night vision.


        How to use the Ballistic Calculator in the Stream Vision app:

        1. Open the Stream Vision app on your iPhone.
        2. Press icon “Ballistics” to go to the Ballistic Calculator.
        3. Press “Set Calculator” to proceed with Calculator settings.
        4. Enter projectile parameters manually or select from the catalog.
        5. Set parameters like “ballistic coefficient”, “ballistic profile”, “muzzle velocity”, “spin drift”, “twist parameters” and others. Press “Next” to proceed with preset settings.
        6. Type in desired parameters and press “Next.”
        7. Press “Next” to go to “Set Outdoor” option.

        You may skip weather setup and default weather parameters will be taken from the preset table. You may later return and set up Weather Setup if you zero in your riflescope in different weather conditions.

        1. Type in preset name and press “Save.”

        You may edit, rename or delete your presets.

        1. Press “Calculate” to have your parameters calculated.

        Set Parameters as Follows:

        1. “Distance” (distance to object) “Angle” (target elevation), “Wind Speed”, “Wind Direction” (0 – front wind, 90 – right wind, 180 – back wind; 270 – left wind). Tap zeroing values below the reticle to change the unit of measurement (MOA/mil/clicks etc.)
        2. Set the range of distances and units of measurement in this slide.

        Setup of the Ballistic Calculator is now completed and it’s ready for use.

        How to Fix a Defective Pixel

        By bmatheus  

        This article was originally published on Pro Staff member Clint Patterson’s website and WeHuntSC.com.

        Have you ever seen a small pixel in your Pulsar thermal optic’s screen that you wish wouldn’t stick out like a sore thumb? If you fire your gun a lot, these pixels that need repair occasionally occur, but fear not, Pulsar has anticipated this and provided a way to resolve it. I had one on my screen for a few months before I investigated and found that it’s simple to correct!

        What is a “Defective Pixel?”

        A “defective pixel” is a pixel within your viewfinder or screen that is “degraded,” sticks out and won’t go away even after your scope calibrates. I’ve owned a Pulsar Trail XP-50 for over 2 years and in this time, I’ve only had 2 defective pixels. Though, when it does happen, over time it will bother you enough to want to know how to fix it.

        In this screenshot, the defective pixel may not seem like a big deal, but when you’re hunting and looking through the viewfinder it can become distracting over time, especially if it’s near the crosshairs. While hunting with the defective pixel shown in the screenshot above, there were several times I panned the horizon and mistook the small white dot for being an animal that was a great distance out.

        How to Repair Defective Pixels

        The first thing to do if you notice a defective pixel or something that doesn’t look correct in your viewfinder is to calibrate the optic. If you haven’t changed any settings on your scope then your Pulsar thermal optic will automatically calibrate every so often to ensure what you’re seeing is accurate, clear and crisp. Calibrating the optic makes the clicking sound that you may have grown accustomed to hearing by now if you own a thermal optic.

        These calibrations can be forced by pressing the power button in the Trail models. If my screen ever gets hazy or I notice something not sharp in the viewfinder, I simply calibrate the scope. With all that said, the first thing to do if you notice a defective pixel is to force a calibration because generally, that will fix it.

        If calibrating the optic doesn’t resolve the issue, then repair the defective pixel by going to one of the last menu options in the menu system, the Defective Pixel Repair option.

        Once you choose this option it’s simple. The system presents you with a pixel selector and provides you with the ability to move the X and Y coordinates. This task feels very similar to sighting in the scope.

        Just move the X and Y coordinates until you are right on top of the defective pixel. As you update the values for the X and Y coordinates, the pixel selector will move across the screen as shown below. The pixel selector surrounded by the box is like the Picture-In-Picture feature and is a magnified (zoomed in) version of the pixel selector.

        The goal is to move the defective pixel selector on top of (or as close as possible to being on top of) the defective pixel.

        And that’s all there is to it! Note that depending on your unique situation, it may take repairing multiple pixels to get the screen back to the desired state. In one of the previous defective pixel scenarios, I had to repair two pixels before it was back clear, and the pixel was no longer bothering me.

        I also made a quick video walking through this process. You can see the video below:
