Beam Diameter of Swarovski LRF?

Does anyone know the beam diameter of the Swaro LRF at say 300, 500, 700, and 100 yards?

I thought this was posted at one time, but didn't find it.

I thought I read 6 feet @ 1000 yards. I don't know if that translates evenly back to say 6" at 100 yards though.

I go this in an email reply from Swarovski in August, 2005.

Thank you for you interest, past purchase, and kind comments about Swarovski
Optik products. The beam divergence on the Swarovski laser guide is a
circular shape of 2 miliradians at 1000 yards, advertised simply at "2
mrad". This translates into 2 yards at 1000 yards, 18 inches at 250 yards, 1
yard at 500 yards, 3 yards at 1500 yards or 4 yards at 2000 yards. The Leica
1200 and 900 series of range finders are advertised with a beam divergence
of "approx. 0.5 x 2.4 mrad" that would suggest a rectangular shape. I
believe one of the differences in the perception is that the Leica is a 7
power unit where the Swarovski is an 8 power. I hope this helps.

Thanks!!!
2 mil is approx 7MOA, which is about 70 inches at 1,000 yards.


Now, my next questions is the diameter of the ring the same as the beam divergence?

Re: Beam Diameter of Swarovski LRF?

U know what i would do with that Swaro Ern.? I'd set up a piece of paper at 100 yds. and measure the reference mark itself. Next thing i'd do is find out where the lowest part of the beam is in reference to the aiming point. I think u could do this by putting up a piece of paper and gradually going up the paper until u get a true reading of what's behind the paper. This way u should be able to determine where the lowest point of ranging is on the reference mark. I'd be real sure u have the steadiest rest possible though.

Dick,

Thanks for posting. Been looking for those numbers for awhile.

I have the Leica 1200 LRF and have been doing some range building. Its a bit of a trick, read much work and and a very steady tripod, to "sight in" the LRF.

Its a bit too soon to tell but I think the beam is cut in about the center by the top horizontal line on the sighting square.

I fully recognize the importance of knowing precisely what one is ranging. Learned that one the hard way.

Roy, I'm using the same rangefinder. Could you explain your statement above a bit more? Are you saying that there appears to be a vertically oriented rectangular beam that the aiming square 'trucates', for lack of a better term? Thanks, Jon
