Angle Compensating Range finders?

Do the new range-finders that calculate "ballistic distance" work for steep uphill/downhill stuff? Would one of these replace the need for an Angle Cosine Indicator? They aren't too expensive and seem like they would eliminate one more variable. Let me know what you have found out. Thanks.

Angle Compensating Rnge finders

Angle Compensating Range finders work out to a point, however they are merely utilizing the "Rifleman" method of determining the "Base" of the triangle. When utilizing an angle compensating range finder, there can be as much as an eight MOA error when shooting at longer distances and while holding on steeper angles.

The Rifleman method is the Least accurate of the three methods used.
The most accurate method for determining your hold on target is to utilize Ballistic targeting Software such as the one that Night Force sells. This is because the software takes into account the BC of the bullet, the bullet's weight, the bullets unique velocity, your zero distance, along with current temperature, barometric station pressure and humidity. With this data, the software will calculate the bullets unique deceleration curve, which you can then take a step further and validate the bullets trajectory. This may sound like a lot of stuff... However it is really very simple and will deliver a very accurate hold.

Doc

They work great for giving Line of site distance at all angles and
ballistic distance.

But you still have to have a good ballistic table to know where
to hold/adjust for the shot at the distance given by the Range finder.

Being some what of a skeptic I tested mine in colorado using a sheer
bluff wall by ranging different distances to the base and then to the top
of the bluff and then at the angle this gave me all three sides of the
triangle.

After doing 10 of these I did the math and was impressed ( could not find
any reading that was more than a few yards off) and most were at the
limits of the range finder.

I did a simular test on the side of a skyscraper in Seattle from about 530yds away. Accuracy is not an issue, I came away very impressed (I was using a leupold RX-III).

Thanks ! Seems like a useful tool for archery and steep uphill/down rifle shots at longer distances. I may have to look into one of these.

Does anyone other than Leupold have one on the market? The reviews on Cabela's site are not to great.
Most complaints were about the rangefinding not the angle feature.
I have nothing against Leupold, I think I have at least 4 of their scopes and love them.
