Question on Degrees on the observation periscope

So I'm setting up an attack on a freighter I just came across, and I'm using an attack wheel made from Hitman's template. I'm using GWX 3.0, and for some reason I'm having trouble keeping a "lock" on the freighter. I don't know if this is due to rough seas, or if this is a feature built into GWX.

Long story short, I took a reading off my obs. periscope of approximately 2.5 degrees, but I then realized that the scale did not change when I zoomed out. The reading was then less than 1 degree. (The markings on the side are in degrees right?).

I then did the same with the attack periscope, for a far different reading of 3.5 degrees, and less than 1.

So, what's the deal? How do I use my zoomed in reading for manual range finding?

Hmm, not sure why you get varying readings at different zoom levels.

I know my attack scope works just fine at 1.5x-6x-15x, I rarely if ever use the observation scope unless the attack scope is damaged but I bet it's OK too.

Are you using any UI modifications? If not, try one and see if that fixes it.

I suggest something like MaGUI. It has its quirks, like auto-closing tubes when you select one from a certain view (UZO I think).. But the optics are accurate and if I stay away from the UZO tube selector switches, mine seem to stay open. Also, you can actually pan around with the scope while the game is paused. I like that, but many would call it cheating :O:

Actually I believe the tube thing is a stock SH3 bug, and I use the TDC selector switches to get around it. Some mods fix it, some don't but I always do switching on the TDC out of habit.

The only mod I have is GWX3.

I think the problem is the degree scale doesn't change when zoomed in. So how do you compensate/calculate off of this?

Hitman was asking about it waaay back in 07

In fact I encountered the same problem that leaded to the 10x magnification: In real life kaleuns were told to use the low power 1.5x zoom to make range and AOB measuring due to the unreliabilty of 6x for that purpose. 6x was limited to target identificaction and evaluation (Tonnage, length...) purposes, so I finally left the calibration for the 1.5x zoom as in real life....but it seems too difficult to get accurate measurements with it.

But, as far as I can tell, never came back with a solution on the forums

the scales are 'tied' at your first zoom .i don't remember the zooms that gwx is using but remember that the scale is tied to the smaller one .so ,when you zoom, it is psysical the image to get larger and covering more degrees . if your low power is x1 and high power is x10 then if target is covering one degree at low power will cover ten degrees at high power . the obs peri,i think in gwx uses different zoom levels from attack peri so you have to look at zooms that obs is using to understand the difference at degrees
