I've had a look at the Vectronix rangefinder/Bino, Terrapin I think it was called, , just the other day, but I wouldn't have called them top end optics at all, and they were huge in size. There is no comparison between them and the EL Range, as they are best at quite different uses. They will range to huge distances for sure, but I would still want a good pair of binos as well, which then means you're carrying way more gear around with you.
If you want to range to 1 mile in bright light, the only options are the new EL range or the Vectronix. No other available range finders will do that reliably. The next best is the Zeiss RF Binos (not the monocular), but they are limited to about 1720 yards.
The EL Range is so small and compact with such an awesome and fully featured rangefinder you are truly giving up nothing by having the combined unit.

Hunter,
It displays a TBR like Leupold's s'posedly, not just a cosign. You should be able to just dial in the TBR come up and shoot, or use your ballistic reticle. I've haven't checked it at a good angle at long range yet to confirm just how accurate it is. I will be in some steep enough mountains shortly and will report back.
Greg
The Vectronicx Terrapin is a monocular.

Re: Swarovski EL Range binoculars - first field tests

Hunter,
I've asked Richard the international sales manager so we'll see what he comes back with. All I can tell you was the results of my field testing. What I did was compare results with the El's with running the calcs on Shooter on my android phone, for 2 different rifles while we were in the mountains. I would pick a spot high above me to range to, then see what corrected range the EL's gave me, then run the calc thru Shooter for that angle and range, work it back to the level range that gave me the same come-ups, then compare with the EL result. In all cases it was within a few yards either way. I ran comparisons out to just under 1000 yards at about 30 degrees, which is a far as the EL's corrected range feature works, and 45 degrees out to about 500 yards. (Its nearly impossible to find terrain that will give you a 45 degree 1000 yard shot.)
I did this for 2 of our 7mm's we had hunting at the time, the 7mm FatMax (7mm/300NM improved) which pushes a 180gn Berger Hybrid at 3300fps out of a 26" barrel, and for the 7mm SF (7mm/338 Lapua imp)which pushes the 180gn Hybrid at 3420fps out of a 28" barrel.
I presumed that as it was so accurate that it actually is a TBR feature, not just a cosign. Trying to get those sort of answers from Swarovski isn't easy, as their grasp of English isn't that great. My understanding from Discussions with Richard Kramer was there is some sort of ballistic calculator incorporated into the EL's, not just a cosign deriver.
I do know it certainly works for serious long range cartridges in the field, but now you've got me thinking, so I'll run some more calcs comparing simple cosigns and see how close that comes. I'd be very surprised if cosigns could be that accurate, but we'll see.
I'll come back to you!
Greg

Re: Swarovski EL Range binoculars - first field tests

I'm new here, but maybe I can help answer some of the above questions as I've been using the EL Range 10x42 since around Christmas time.

The model that NZ Longranger is reviewing is the same model that is available in the US. They are rated to 1500 yards, but I've ranged light-colored bovines at nearly 1900 yards, and rocks past 2000 yards.

They range on button release, which helps hold them steady when ranging small targets or long distances. The reticle for aiming is in the right side, the yardage display is in the left side, which is one reason for their superior optical performance.

Optically they are equal to the pre-Swarovision EL binoculars with 90% light transmition through both tubes. The other RF binos suffer from fairly poor light transmission in the tube that houses the reticle. There is an immediate and obvious edge in optical perfomance when compared to other RF Binos.

Beam divergence is listed as .5 mrad wide by 1.5 mrad high, though I have no way to test this. They are very effective at picking up small objects at distance, especially when tripod mounted.

The angle compensation has 2 modes. It will either display line of sight distance and angle in degrees, or LOS distance AND angle compensated distance (under 1000 yards). Since there is no way to input any variables such as velocity, bc, etc. the corrected distance is calculated using the cosine of the angle.

Even though they are only a few ounces lighter than the Geovid, the open-bridge design and thier overall compactness give them a feel of being much lighter in the hand.

They are very limited in availability, and unless you have already placed an order for one, you are unlikely to get your hands on one until late in the year. They've been shipping since early Jan.

I hope this helps clear up some questions.

Re: Swarovski EL Range binoculars - first field tests

Kilmer,
You certainly sound like you have the info, but I can't quite make what you're saying work with my own field tests and calculations. You may be correct that it just takes the cosign of the LOS distance, but if this was the case, it should be miles out once you start getting steep and out a bit.
I just ran some calcs for one of the examples I actually tested in the field, and that was for the 7mm Fatmax pushing a 180gn Hybrid at 3300 fps. When I actually ranged a little alpine bush at 800 yards above me on a 30 degree angle, the El's gave me a corrected range of 745 yards.
Now when I compare my calculated drop from my 100 yard zero for 800 yards and 30 degrees for this, I get 88.2". Then do a level drop calc and you get 747 yards for the same drop. So for this example, the EL's were only 2 yards out. If they just did a cosine of the LOS distance, that would be 800 x .866 = 693 yards which is a drop of 72.5", so an error of about 55 yards and about 16". In all the examples I ran in the field, they were never more than 3 yards out.
I presumed they have some sort of ballistic calculator in them that picked and average trajectory curve and then worked out a TBR on this. That is the way Richard Kramer described it to me, as best I could understand. If you do some calcs running some comparisons of what sort of maximum angles at what sort of ranges you are likely to actually strike while out hunting even in the steepest mountains, you'll see an average curve actually puts you within a few inches all the way to 1000 yards. My point is you don't actually need to be able to input the various trajectory curves etc to get close enough out to 1000 yards, an average curve will do. You don't need velocities, BC's etc. You are only applying a TBR correction to your the level range come ups which already have all that for your particular cartridge incorporated.
Hopefully you follow what I mean?
Anyway, there is no way I could be getting the results I've been getting in the field if the EL's only applied the cosign to the LOS range. Unless my set have some basic offset built into them that just happens to have worked for the examples I tried in the field, but I find that very unlikely as I tried everything from 400 yards and 45 degrees out to 999 yards and 25 degrees, and they were within a few yards every time for the flat shooting 7mm's I was carrying at the time.
So please tell me how this is happening???
Greg

Re: Swarovski EL Range binoculars - first field tests

Here is where it is hard for me. I already have els@ 20 oz. then Lieca 1600 @8 oz. pretty good combo and lighter . Then for $2000 I could get the PLRF 05,this puts me at similar weight and probable performance, but has only 5x mono. Which I have seen Shawn C, put a doubler on his and I HAVE ONE FOR MY ELS ALREADY. T he unit sounds great, just hard up grading all the time. But my rifle out shoots my old 1200 Lieca

How about that? I assumed that because my ballistics calculators and the EL Range pretty closely agreed that they were both using a cosine correction formula to adjust the range. After having spent the last hour playing with calculators, I must say that I stand corrected. There is obviously something more at work here than a simple cosine calculation. When I input a 30 degree angle at 800 yards I get anywhere from 715 yards to 765 yards corrected distance depending on caliber and calculator. Straight cosine would yeild 692 yards.

There must be some sort of statistically averaged ballistic profile that they use for calculation. I'm going to find out.

I stand firmly by everything else I posted, unless NZ Longranger says otherwise.
