Kong, Most of the time I use land mode on the Shore batteries. I left click and hold on the SB icon and zoom the map all the way in. Then I release the left click button and left click again just behind the SB icon. That will give you a pretty close or spot on range. I do have a problem though sometimes when the SB is on a little mound. When I try to elevate the 8" barrel near the top of the mound, the range will decrease instead of increasing when I tap on the "W" key. It only happens at the top of the mound and makes targeting the SB very difficult. I noticed that on the CraterMA map the other day.
