Zeroing the Pulsar N970 LRF Digisight using the One Shot Zero function.

Zeroing the Pulsar Digisight N970 LRF with live ammo using the One Shot Zeroing function.

 Zeroing a traditional Night Vision (NV) Tube type riflescope.

One of the many limitations of traditional tube NV devices is that you can only use the device in complete darkness, so zeroing before going out foxing at night is an issue.

Most NV users have a day scope for hunting during the day, and switch to the NV scope at night, meaning a rezero each time, or if you are lucky enough to have two rifles, swapping rifles between day and night.

You would normally have to zero the evening before as daylight can severely damage a tradition NV tube riflescope which means they can only be ever used in complete darkness.

Most tube NV devices have a rubber lens cover with a small pin hole in the centre to limit light ingress, to allow you to check operation indoors, or away from bright sunlight, but they are limited to that.

Actually zeroing a rifle at night is very difficult, it is harder to judge distances and it is difficult to see the target to check impact position.

Zeroing the Pulsar N970 LRF Digisight and Digisight Ulatra N250

The Pulsar N970 LRF is very different in that it is not bright light sensitive and can be used during daylight hours, so zeroing or even hunting during the day is perfectly fine.

The N970 or Digisight Ultra N250 can be used as a day scope, and also as night vision scope, so negates the need to swap riflescopes on your rifle.

Although the Digisight will not offer the clarity during the day as a daytime scope, it is perfectly capable on small and large calibre rifles, and shooting to 200meters and beyond is no issue.

As with all telescopic riflescopes it takes time to know the device, and to actually zero the rifle to the scope, to ensure each shot is perfectly placed.

The Digisight N970 and Digisight Ultra N250 features two zeroing methods, traditional zeroing and One Shot Zeroing.


Traditional Zeroing

Zeroing of the N970 should be done at normal operating temperature and by following these instructions

1. Mount your rifle to a bench rest, or use a bipod and sand bag set up to ensure your rifle does not move position between shots. If you don't have a bipod or benchrest, then filling some sacks with sand is perfectly fine.

2. Set a target at a distance of about 100meters, ensuring you have a safe backdrop such as sandbags, a mound of earth or similar. The N970 telescopic optics feature 4.5X magnification and will allow clear viewing and impact acquisition at this distance.

3. Turn on the riflescope and the display will illuminate. Adjust focus, sharpness until you are happy you have a clear image of the target at 100meters.

4. Looking through the N970 match the reticle centre with that of the target.

5. Using live ammunition, ensuring the range is clear, fire a shot, continually aiming at the same hit point on the target.

6. Examine the target and determine if the aiming point coincides with the point of impact. If you determine it is necessary to make corrections, you will need to adjust your aiming point using the adjustment knob.

7. Using the adjustment knob, one click moves the windage/elevation 20mm at 100m horizontally or vertically.

8. Check the accuracy of your adjustments by firing a group of 3 or 4 control shots.

9. Recheck Point 6, make adjustments if necessary, and then fire a control group again.

10. The scope should now be zeroed in for the specified distance.


Pulsar N970 One Shot Zeroing

Pulsar have included a One Shot Zero function to make the set up process even easier and this sounded all too good to be true we must admit.

However we followed our manual and set up a rifle in the range to zero using the One Shot facility.

As most people will be using a bipod we decided against the bench rest, as in the real world people don't have the time to do this we feel.

On our first attempt at One Shot Zeroing we were more than impressed, and despite finding it hard to hold the rifle steady (it was bitterly cold) we managed to zero our Digisight perfectly using this facility, so have no hesitation in recommending it.

1. Follow the first four steps of Traditional Zeroing, get ready to fire a shot.

2. Fire a shot at the target.

3. If the point of Impact does not match the target centre, push the M button to enter the main menu and choose the Zero option, which is indicated by an icon of a Bullet. Our demo video shows the shooter entering this mode.

4. On the right of the Icon appears an upwards and downwards arrow and an auxiliary cross appears in the centre of the aiming reticle. This can be easily seen on the demo video, and this auxiliary cross will indicate the centre of the target, the "bullseye" if you like.

5. Holding the centre of the auxillary cross (C) in the aiming point, rotate the windage elevation knob (the click wheel on the side) and move the reticle horizontally or vertically relative to the auxillary cross until the reticle matches the point of impact (P) To switch between movement direction push the knob to hear a click.

6. Once you have aligned the reticle with the impact point, keeping the Auxiliary cross in the bull, take another shot. The point of impact should now match the target centre (T)

7. Exit the menu option by holding the M button for one second.

8. You should now be ready to go, with a zeroed Digisight at 100meters.
