You have to enable it separately, and I've noticed a BIG difference. You can pick up and track large targets from much farther out in general. For example, I just came across a carrier group tonight that I was able to track at over 19 miles...it didn't even show on the PPI scope yet but I could zero in on the carriers & cruisers with the range finder. It took a while to show the escorts (as it should, they're smaller) but I could pick them up at about 12-13 miles with the regular SJ. Your radar range is easily doubled in some situations.
NOW if we could just simulate tubes & capacitors burning out at the worst possible times.....
