missing the neotropics
124m is just over 406ft.
But if measured at 1000m instead of 1000 yards it works out to exactly 372 feet at 1000 yards.
124m is just over 406ft.
Too many vids, and ultras are no longer ultra, so it makes sense they consolidate down to Trinovid and Noctivid.
406ft at 1000 metres. Not at 1000 yds.
It may well be that Leica has also got it wrong.
This 9% error appears repeatedly here and elsewhere.
Very simple. Measure it directly. Preferably against star separations.

Maggie and Jake Gyllenhaal.
P.S.
400m at 1000m is 22.9 degrees.
Even the 4x21 (3.5x21) Xtrawide is only 18.5 degrees.
The Nikon afocal adapters recently mentioned and the 2.1x Vixens should manage this.
At such wide angles I am not sure that the two measurements are applicable as one is a flat plane measure, the other a spherical measure.
Jake would have the Leica rangefinder to measure his sister's distance and the 1000 metres to the observer.
Needs good light and no foliage in the way, as one tends to measure the distance to a leaf and not to the distant observer.
Comparing this new Trinovid to the CL isn't really that flattering IMO, as I find the Swaro CL to be their worst offering, by far.

We are both crackers.
Well, at least I am.
If Leica are claiming fields at 1000m, they should do just that.
Build a straight wall exactly 1000m away centrally from an observing platform.
Scientific lasers measure the Moon's distance to 10cm, so 1000m can be known to 1/1000 mm. But 10mm is good enough, even 100mm.
Or surveyor's equipment.
Then measure off the markings on the wall.
At 8 degree field I think the wall is actually 1,002.5m distant from the observer at the field edge.
However, with a 20 degree field the wall is I think 1,015.5m distant at the field edge.
I have a problem with these linear field measures.
The real world is spherical. The horizon is round not straight.
The Earth is not flat, except for the flat Earth society.
For military use, I accept that reticles measuring linear sizes are useful.
But I think in degrees for field sizes.
I understand Wernher Von Braun was asked to believe that we actually live inside a spherical Earth.
I doubt he actually believed that.
