Declination and Silva Ranger

[ccrn]

Ive been using my Silva Ranger more and more on Landnav courses as the idea of keeping the needle in the "North" indicator becomes more comfortable as opposed to just using the degree card on a lensatic. to sight in.

The question I have is do any of you just add or subtract the amount of degrees for declination on the Ranger, adjust the bezel, then move out?

Because the problem I am having on my specific compass is the little screw on the back for adjusting declination seems to move and I"ll find that it is off somewhere along one of my legs. It would seem more dependable to just not use that feature and add or subtract for the declination (as you would on a lensatic) and go from there.

Does this make sense?

Can someone sqaure me away on this?
Thanks-
