For those of you with the swarovski range finder..... One of my gripes about this unit is the dioptric eye correction that is adjusted by a twisting action. As you know, there aren't any detents or the like to keep the adjustment in place like there is on swarovski binoculars. More often than not, when I pull the RF off the belt clip or out of the pack, etc., the adjustment has moved, making for a blurry view. Has anyone come up with a solution to keep the eye piece from inadvertently moving? I don't like having to fuss with the unit when time is of the essence in a hunting situation. The only thing I have come up with thus far is to make a line with a magic marker on the eye piece and unit that lines up when properly focused. However, I don't always remember to take a look at it when I am pressed for time and the target is making its way out of sight.
