I have tried in vane to find out the 'C' dimension (horizontal opening) at 2x & 12x magnification for the Swarovski Z6 2-12x50 TDS 4 reticule subtension. Our importer had no documentation with this information. They wrote to Swarovski in Austria and could not get the information! I have a PVI2 with the TDS reticule, and am thinking of buying the Z6 with the same reticule while there are still some available. I would like to compare the subtensions first. Can anyone help? Thanks.

The 'C' measurement is the reference used in the Swarovski manual illustrating the distance between the horizontal opening. This is measured from where the 'heavy' horizontal post changes to the 'fine' hotizontal line to where the 'heavy' post starts again. It is expressed in centimeters @ 100 meters, or inches @ 100 yards, at a given magnification. (For 2nd immage plane reticles.) The subtensions are usually given at the minimum and maximum magnification for the particular model of scope.  Sorry, abit long winded!

The measurement of the horizontal opening for my PVI-2 High Grid, 6-24x50 TDS 4i, taken from the scope manual are as follows:

Field of view at 100 yards (100 meters) between the heavy horizontal posts of the reticule.
100.8" - 25.2" (280mm - 70mm)

First figure 6x power, second figure 24x power.

As I am familiar with 6-24x TDS 4i reticule, I would like to know if there is any parity with the same reticule on the Z6 2-12x, and if not how close the measurements are. It may make the difference in my choice of reticule for the Z6 that I intend to buy.

there will always be a parity at some magnification, , but at six and 12 , I guess the measuring will tell, even if the scopes were designed as such or with that intention in mind the quality control of the total process would still be about 1% off. they are not precision optical instruments. even high dollar milling systems are off. just for starters, though I'll bet they are pretty close.

My primary area of interest with the comparison is at 12x mag. With the information I seek, I can compare the different reticule subtensions for the Swarovski reticules available. The purpose of the Z6 is for close bush to 250 meter plus deer hunting. I am tempted with the 7A, but am leaning towards the TDS 4 reticule (due to my familiarity with the reticule on my varmint rifle). I am very frustrated and disappointed by the fact that I cannot find the information about the product that I wish to purchase. I disclosed the serial number of my 6-24 Swarovski scope in the correspondence with our importer to give them assurance of the genuine nature of my enquiry. Still no result.

A friend has a Z6 2-12x50 with a 7A reticule. The subtensions are clearly printed in his scope manual. Why is this not the case in the manual for the TDS 4, or TDS 4i reticule for the same scope?

can say why, but the tds in the z6 does well, and highly recommend the unit in discussion. my guess is that this dimension isn't used much so no body ever got around to checking it out.

the subtension is 23" at 107 yds, (too lazy to move up) tape wasn't long enough to measure at low power.  sounds very close to your other scope

Thanks for taking the trouble to measure the field of view. Your findings are similar to the limited information that I have. What it has confirmed is that, assuming your scope is a 2-12x50 Z6 TDS, the information in the manual relates to that model at 12x mag. The manual gives a measurement of 25’ @ 100 yards, but does not state for which model or at what magnification.

I have since viewed a Z6 2-12x50 with 7A reticule, and the manual. The horizontal and vertical openings are much bigger than the pictorial representations in the literature suggest. The horizontal opening at 12x mag is 43.31” (120.3 cm). This is almost twice that of the TDS 4 reticule. Does anyone have experience with the 7A reticule?

Thought I mention that SWFA's website has the Z-6 'Plex' and '7A' reticles pictured wrong.  The 'Plex' is pictured as a 'heavy duplex' and the '7A' as a standard duplex.  This is backwards.  The 'Plex' is standard sized and the '7A' is the 'heavy duplex'.   I confirmed this with Swarovski Customer Service.

All the representations I have seen everywhere for the 7A reticule are significantly incorrect when compared to a view through the Z6 2-12x50 7A scope, including the images on the SWFA web site. If it is possible to upload a photograph taken through the scope I have with a 7A reticule I will do so to illustrate the point.
(The proportions of the reticule do not change with magnification as the reticule lies in the second image plane.)

It only took about a 100 takes to get this VX-111 illuminated B&C.  Just kidding!  I took this after 5 or 6 tries holding the camera with one hand and the scope with the other.  Not a great picture but it's good enough to see the reticle.

All references are for the Swarovski Z6 2x12-50
The pictures attached are for the 7A reticule at 2x & 12x.
The Swarovski manuel give the following measurements for the horizontal (& vertical) openings:

            100 yards   100 meters
At   2x = 258.73"      (718.7cm)
At 12x =   43.31"      (120.3cm)

The  subtension measurements of the 7A are nearly double that of the TDS 4! (25.4" / 100 yards at 12x mag according to my information)
To those of you that own the TDS 4 reticule, how does what you see compare to my images of the 7A?

I forgot to add, but the 7A reticule here looks nothing like any of the advertised representations!
