How to Use Pulsar’s One Shot Zero with Freeze Function!

Even for a guy who makes part of his living shooting, sighting in can be maddening. Environmental conditions, even at 100 yards, can wreak havoc on one’s ability to establish a group they can really trust, and worse, open your groupings up as your stress level increases. Heck, I’ve seen seasoned golfers on putting greens throw their putters into the drink—the same definitely applies on the firing line, especially when you’re counting on your skill set rather than a Lead Sled.

Often, a staple of frustration when sighting in is dialing adjustments. It’s easy to chase your bullets and is, after all, often effective. In doing so, you aim at the bullseye, shoot, note your position of impact (POI) and then rightfully hold dead-center again while you adjust your windage and elevation to shift your crosshairs to the POI; of course, you just about have to be a brain surgeon to keep your rifle still enough to make those adjustments or you risk walking shots in… or make things worse altogether. For some, the frustration often results in “good enough” closure but often, it’s not good enough.

Sighting in using the One Stop Zero with Freeze function is quick and easy.

Fortunately, Pulsar understands our plight and came up with a perfect solution to the sight-in blues—One Shot Zero with Freeze function. I would ask you to imagine a world where you could follow your POI, without moving, and be on the money after a single shot… but, the technology is already available in Pulsar’s current lineup of dedicated thermal and digital night vision riflescopes.

In a nutshell, the shooter sends one down range and notes the POI. For thermal, I like to sight-in at 50 yards and also double my base magnification—often this reveals the point of impact, still warm from the previous shot. I freeze the image and then position the secondary adjustment reference, an “X,” over the first POI. I save the data and shoot again. My second shot should be center mass.

Now let’s take a look at how to use Pulsar’s One Shot Zero with Freeze Function step by step.

  1. Mount the Pulsar optic on your rifle, aim center-mass on your target at a known distance (I prefer 50 yards for thermal) and shoot.
  2. If your point of impact (POI) doesn’t match your aiming point (AP), long-press the menu “M” button. Using the up/down arrow buttons, move your cursor to the “Zeroing” submenu, annotated by an icon of a reticle in a circle.
  3. Short-press the “M” button to enter Zeroing submenu and select the appropriate distance. If it does not exist, you can create a new zeroing distance by selecting “Add New Distance.”
  4. Once the distance has been selected or created then selected, used up/down arrows to select the submenu “Zeroing,” this time annotated by a reticle without a circle.
  5. Aim at center-mass on your target again and use up/down arrows until your cursor points to the Freeze option (snowflake icon). Short-press the “M” button to freeze the image.
  6. Once you have selected “Freeze,” you no longer have to aim at the target—feel free to move and make adjustments. To do this, use the up-arrow button to move your cursor to the “Windage” icon annotated by an icon of arrows pointing in all four directions like a wind vane. Short-press the “M” button to select the “Windage” icon. Short-press the “M” button again to highlight an axis value, X or Y. Short-press the “M” button again to toggle between X (windage) and Y (elevation) axis.
  7. While an axis is selected, X (windage) or Y (elevation), use the arrow buttons to change the numeric values. As the numeric value changes, an auxiliary “X” moves off of the reticle center. Use the appropriate axis and up/down arrow buttons to move the auxiliary “X” to the POI. As a side note, increased X-axis (windage) values move the auxiliary “X” to the right (shifting POI left) while decreasing the numeric value moves the auxiliary “X” left (shifting POI right). On the Y-axis (elevation), increasing the numeric value moves the auxiliary “X” up (shifting POI down), while decreasing the numeric value moves the auxiliary “X” down (shifting POI up).
  8. Once the auxiliary “X” is over the POI (bullet hole of the previous shot) on the display, long-press the “M” button to back out to the “Windage” icon. Long-press the button again until the message “Zeroing coordinates saved” appears.
  9. When the message disappears, you’ll be back at your distance submenu. Long-press the “M” button again to back out to the “Zeroing” submenu. Long-press the “M” button again to back out to the main menu. Long-press the “M” button once more to return to your reticle and real-time field of view.
  10. Take a second shot to confirm your POI now matches your AP.
