Manual targetters: How the $%#* do you get a decent range with the Stadimeter in anything but totally calm water?? I've been using the average technique - like take 3 readings and do a rough average, but in light winds I find my estimates bounce all over the place making it impossible to get a decent range. Without the target speed estimate (which I derive from three or more range estimates), I can't make a good shot.

Second, semi-related issue - how to determine target speed (forget bearing & range - just speed) with the hydrophone? In DW there's a DEMON analysis that one does to determine this. How to do it in SH3? I can line up a shot abeam by eyeballing the AOB, but the speed is hard to get right - an accurate measure by hydrophone could really help and eliminate the need to use the Stadimeter in rough weather.
