How to Zero:
- In Settings, type in the target range and the scale.
- Fire a four (or more) shot group at the target center.
- Touch the screen to move the red "X" circle to the center of your group.
- Make the turret click adjustments shown.
- Your are now zeroed!
- Fire some shots to confirm, if you like.
After you have adjusted your turrets you are zeroed. Feel free to fire another shot to check.
If the target isn't at the zero range, this will set the green circle the correct impact point.
I want a 160 yard zero, but the target is 25 yards away.
So you may have to impact a little above or below the bullseye at 25 yards to be on at 160.
The program will do this for you.
- Select "Use Advanced".
- Click on Advanced, fill out the details.
- On the Main Screen, the green circle will usually on the center of the target if "Range" And "Zero Range" Are the same.
Otherwise the green circle will move to show the correct impact point.
"Sight height" is center of muzzle to center of scope objective or tip of the iron sight. It is important to get this right
Find out the BC of your bullet and the muzzle velocity.
These numbers are usually on the ammo box, or on the manufacturer's website.
If you have a chronograph, use that to measure muzzle velocity.
Type in atmospheric pressure, altitude (Most weather reports adjust pressure to
sea level, this adjusts pressure to your location), temperature,
and humidity (humidity doesn't make much difference).
Select "G1" unless you are sure you really want "G7".
"Metric" gives you all metric units, "USA" all Imperial.
Select "Use Advanced", put the red "X" in the center of the target of the target, that gives you the adjustment for the current range.
Tap and hold the "Range" button to cycle from 25 yards to 1000 yards.
