Ranging question

[codyhuntsaz]

I'm using a new Sig kilo 2000 range finder. It has a line of sight option and an angle modification option. I'm wondering which one I should use if I am using MOA turrets on my rifle.

Angle. Always angle.

Angle. Always angle.

This math never lies .. All about input / output ....

[5guyshunting]

Angle will be more accurate than line of sight.

[lancetkenyon]

Yep, angle. Unless you have a degree of incline feature. Like -4° 842 yards. Then you input into your ballistic app.

[Big or Bust]

Angle always. That's why it comes already set that way....

 

I was glad for it a few days ago. 620 yard shot on a deer 400 feet below me...

[AzDiamondHeat]

I wonder why they even have the line of sight feature still. Is there a purpose for it?

Golf!

Thanks guys. That's what I was thinking then I went and did something dumb.....read the manual. It confused me.

Real men dont read the instructions

If you are using a COS indicator and ballistic app, then line of sight feature would be more accurate. If you aren't using a COS indicator and app, go with angle.

[308Nut]

The most accurate method is to input line of sight into your app and the angle of incline. The app will calculate your drop. Short cutting with the "hold for" method gets you close but isn't perfect. The hold for method is the least accurate. The MOA * COS hold is more accurate but not perfect. Put the right numbers in the app and let the app do its job.

[300RUM]

The angle function multiplies your line of sight distance by the cosign of the up or down angle to your target. The adjusted "angle" distance is what you would base your elevation adjustment on .Wind does not care if you are aiming up or down. The bullet has to travel the line of sight distance through the wind all the way to your target. For windage adjustments you still need the line of sight distance.

Explains the two options again? I have a 1600 b Leica and all I do is put in the yards and add the degree in the app. That's good,enough right??!! What's the angle options?

[300RUM]

When you fire a bullet at a uphill or downhill angle You need to correct the range used for your elevation adjustment to what it would be if you were at the same elevation as the target and firing without raising or lowering the muzzle. This is accomplished by multiplying the actual range to the target by the cosine of angle to the target, based on 0 degrees at horizontal. Many new range finders have a option to provide the user with either the actual range to the target or the corrected range to the target, adjusted for a incline or decline, and can be switched between the two. Check the manual if you are not sure. A gun mounted ACI or ADI can also measure the angle, figures tend to get rounded and a little precision is lost. Some ballistic programs can use some phones to measure the the angle. However we do it the range to the target needs to be adjusted if the target is uphill or downhill. A 500 yard shot at 30 degrees uphill would be considered a 433 yard shot for elevation adjustment. 500 multiplied by 0.866, the cosine of the 30 degree angle. Ballistic programs will do the necessary calculations for us with precision but we have to enter the correct data. If you are using a ballistic app check what it wants entered, the actual range to the target and angle to the target or the adjusted range to the target. I expect most apps want the actual range and angle so they can do the math and because windage adjustments need to be done based on actual range. Check your range finder to see that it is providing what the app is asking for. If you enter the adjusted range from a rangefinder into an app that expects actual range the provided firing solution will be off.
