angle cosine or angle degree

Angle cosine or angle degree indicator , which is easier to use ? Also, do they require a picatinny rail ? At present I have the one peice Talley base and rings for my Rem 700 STW, so how would I mount an angle indicator ?

If you don't want it mounted or you want to go the cheap way just use a protractor with a string and a weight at the end(such as a pen or pencil) or Google "slope doper". These are cheap alternatives that work.

Check the ballistic software that you normally run and see which it asks for. The version of Exbal that I use ask for the Incline Angle in degrees. Others will know better than I but I think if you use a drop chart and just do the math for the angle the Cosine would be a better choice. Do a search. There was a thread that really got into this just a while back.

I'd vote "cosine" units on the device --

You can use software or prepare you charts to handle the cosine value with little to no extra effort...

HOWEVER, if you ever find yourself without your Pocket PC/charts/calculator and have to do the math "by hand" in the field, simply multiplying by the cosine value supplied by your angle measuring device is a helluva lot easier than multiplying by the square root of (1 - sinē X), where X is the angle in degrees read from your device At least for me anyway...

I guess you could commit cosine tables to memory -- but who has braincells for that?

Part of my question also should have been which is going to be more accurate, cosine or degrees ?

They're both easy to use, just go with what you like beter. Right now I have the cosine, my next buy will be the one in degrees.
Also, do they require a picatinny rail ?
Depends on where you want to mount them, they can either be mounted on the scope or the pecatinny base. If you get the one the already comes with the mounting device for the price, then you just mount it where you're suppose to. I have been advices not to mount them on the scope if you're using a 1" tube. Is not believed to be strong enough.
At present I have the one peice Talley base and rings for my Rem 700 STW, so how would I mount an angle indicator ?
The mounting is easy, don't worry about that, the instructions that come with the unit will have pictures and explain how to mount it.
I hope this helps. A good advice from former post is for you to make sure that the ballistic program you plan on using will handle your choice of angle reading. My version of Exbal does both on my pocket pc and LoadBase 2.0 from Patagonia Ballistic does also both.
Good luck!
