Re: Angle Doping???

I walked in one of the local warehouses and there is was... can't remember which one.
you may try:This LInk $10.39
If the link does not work, type in Yahoo search engine
"dasco pro angle finder" without the quotes and it'll take you to it.

It's not that low cost but it is precise. It is cheaper than the cosine tool.



I'm thinking one of these would do just what we're looking for. Craftsman 6-1/2 in. SmartTool Plus Module Sears item #00939756000.

Just aim at the target and press the hold button. Now you have the exact angle to the 10th of a degree. It even reads in percent to simplify the yardage calculation. For aiming a guy might just mount it to a small scope and keep it in a pocket or just simply sight down the flat edge.

It is not attached to the rifle and is slower to use, it is also difficult to hold the rifle on target and hold and read at the same time.Also requires you to figure the cosine. The cosine indicator is simpler to use and the cosine is giving to you not the angle which makes it much quicker to use. The cosine indicator is worth the cost in my opion........

A true cosine would be meaningless to the average guy. That's why the reading in percent just like the ACI gun mounted tool does would be so handy. The electronic measure with the hold button potentially would be more accurate. The other simple angle finders require two people to read it. One to aim it, the other to read it. The electronic one you could use by yourself just like the ACI unit but is much cheaper and handier to get a quick reading.

The term cosine is misleading. It really indicates percentage from 90 degrees to level. Example
A reading of 76 percent from the ACI or the Craftsman tool applied to 15 inches of elevation correction would be .76 x 15 = 11.4” correction for the shot.
A simple angle finder requires the addition conversion. 68.4 degrees on the angle finder would be converted for the shot. 68.4 / 90 = 76 percent x 15 = 11.4”


The reading in degrees from the angle finder is still going to have to be converted with a calculator to percentage. Now tell me just what 73 percent of 18.4" inches of drop is while your holding your rifle on target. Do you have a calculator or a palm pilot with ExBal mounted to your rifle too? No matter how you do it, you still have to put the gun down to do the calculations. Why swing that bulky rifle up for an angle reading?

Re: Angle Doping???

I thought the ACI readings were cosine numbers! [img]/ubbthreads/images/graemlins/confused.gif[/img]
I understood it as:
If, ACI reading = 94
Then, multiply .94x(ranged yardage) and use the drop data for the outcome.

Example:
ACI reading = 94
Ranged yardage = 465
.94 x 465 = 437
Elevation value for 437 yards = 5.1 MOA
Dial 5 MOA up and squeeze!
Is that right?
It sounds like I just need to sell some stuff I have laying around and get an ACI, just hope I get enough $$$ to do it.

It seems the easiest would be a pocket ballistic program and enter ACI reading in it and use the firing solution it gives.

Cosine really means the ACI is giving you the Cosine of the slope angle that you're shooting measured from the horizontal. When you read 77 on the ACI it really means that you’re shooting at a vertical angle (up hill or down hill) from the horizontal of 40° degrees. The Cosine (40°) = 0.7660, so a reading from the ACI of 76 or 77 will be close enough to say is a 40° angle but ACI gives you the information that would be more ready for you to use, that would be 76 or 77.
