Recently installed a ACI on my Deer Rifle. Very interesting when shooting at a down or up hill angle. Just multiply the value on ACI by measured range and you get the ballistics target range value.

Anybody else have experience with this kind of thing? Seems to work for me.

Will it also mount on the right? Nice scope by the way. USO make the ACI as well? I've not seen it on their site.

No, SniperTools, makes the ACI and is not connected in any way to USO. Will mount to the right, but then meter would be down side up!

not a bad thing to have near a range estimating reticle.
Many of us wait for the laser rangefinders that do the same thing to be a little cheaper.

I know it need batteries. I know electronic stuff is not so reliable.
But coming from a guy that used sin and cosin tables (it was actually a pretty thick book) to calculate the trajectory of an artilery head.... all this because someone was paranoid to not use pocket calculators.... they would fail in case of a nuclear deflagration or an EMI .... I wouldn't worry about it too much.
 
Yes, Sir!

Affirmative: Scope is SN-3 Metric TPAL with Lit H-25 HORUS (AKA CANADIAN HORUS)

Checked out LIECA VECTOR, has Tilt to 35 degrees, US$7500 on last view.
