To me, it sounds like you might make use of a rangefinder because the focusing on those things is binary.
The split-image screens are reliable, but you need a straight line or object at right angles to the split to take best advantage of them. I prefer a plain microprism dot myself. It really comes down to you, and what you're focussing on.
