[Puster Bill]

While we are on the subject, I have a suggestion to "improve" the slide rule/omnimeter portion of your most excellent wheel, Hitman.

On several occasions, I have found that my relative bearings between two different observations had less that 6 degrees of difference, and this can cause a problem with using a standard sine scale.

Usually, I see this happen when the target is moving slowly, or I am at a very small AOB relative to the target, or because of circumstances (low visibility, an escort heading towards me, etc.) I have to use a small time period between sightings.

When this happens, I pause the game and go through the tedious procedure of converting the ranges from meters to yards so that I can use the US IS-WAS/omnimeter that you made. It has an 'ST' scale that allows you to use two observations with less than 6 degrees of difference.

If I don't have my US version with me, I have to either do the whole procedure on my linear rule (which introduces more possibility of error: I sometimes screw up the speed calculation), or more likely I try to guesstimate where the particular ST value would be on the S scale.

The other advantage of having an ST scale on the wheel would be that it would allow you to do fully manual range estimates. In other words, you look up the mast height, use the reticle to find the angle, then use the wheel to figure the range, which you would enter manually into the vorhaltrechner. You can't do that with the US version, though, because the scale is very rudimentary and only shows whole degrees.

Just something to think about.
