started a second career today using manual TDC and things did not go nearly as well as I'd hoped.  
The first thing I noticed was that virtually all of my range estimations (using the stadimiter) were well short of the target's actual range. I think I'm using it correctly: setting the horizontal line in the periscope along the waterline of the target, selecting the correct ID in the recognition manual, bringing up the image splitter/stadimeter, and placing the waterline in the top image on the top-most point in the bottom image. At first I thought I was mis-identifying the targets, but the sampan fishing trawlers couldn't be misidentified because there was only one with the correct number of sails.
The other thing I noticed is that, over time, the position keeper appears to get confused as to where the target actually is. The only thing I can think of is that my constant re-configuration of the target info is confusing it?? The lack of a functioning chrono is certainly hurting my speed estimates, but I think I can overcome that. I've got the 'turn off map updates' off, so I'm cross-referencing where the target appears on the map with where the TDC thinks the target is (white X with a tail indicating direction of movement). 
Any assistance would be greatly appreciated!!! |
Did you check what measurement units the stadimeter is giving you? |
How would I check that? Anyone got a quick conversion from yards to nm?

Oh, and the stadimeter measurement is supposed to be done while the scope is at high magnification (although this would lead to over rather than under reading).

I am using imperial measurements and I would expect that the proper information is being passed from the stadimeter to the PK. I am using high-magnification.
I know one other poster suggested it: can we get a picture of the correct stadimeter alignment? I'm guessing it's something I may be doing incorrectly, as my ranges are usually off by about 1/3rd.   |
2000 yards = 1nm
