Range Finders

I have one of those, i like it quite a bit. If your targets fairly reflective, especially against a less reflective background it will pick up some pretty small stuff out past 800yds. Deer sized game best i could do was 400-500 with mine, smaller stuff like a goat 400s about max. I havent really got to play with it too much, half the stuff ive tried to range was bow hunting, the other half was already running away, or i was using the range finder to pick them out of rocks or bushes.

One thing to consider is that it has a red lcd display which means its got a blue tint to make the red show up better. Ive found thiz takes some getting used to when using it to find brown animals. As the brown color lost, to a degree, in the greens.
 
I checked the user manual for this rangefinder and saw no setting for altitude above sea level.

At 1000 yards with a 308 Win cartridge, there's a 4 to 5 foot bullet drop spread from zero to 7000 feet elevation. At 600, it's a 10 to 14 inch spread.

Ambient temperature isn't an input, either; that causes a smaller spread.

I'm at about 1700ft I'll have to play with the calculator and see if it's accurate enough to be usable.
I'm going to assume that I can't afford a real good one that does drop compensation correctly.
Is the bushnell unit good otherwise? It's about the same price as the brands I would expect to be excellent quality for price like the vortex 1000 unit. I know the bushnell scopes come in all levels of quality clear down to the bottom.
 
I would not trust the ballistics to a high confidence. Short range, maybe a medium confidence at best.

Bushnell has the CONX package, or you can use the LRF and a Ballistic Calculator table, built off current atmospherics.
 
Sierra's software in their Infinity Suite has the best stuff I know of for sight settings for different bullets and muzzle velocities at different ranges and elevations. My firing test results for 30 caliber bullets leaving 2450 fps to 3200 fps from 100 to 1000 yards at 300 to 8200 feet elevation matched Sierra's calculations within one half MOA.

Chrono your bullets then calculate sight settings for your stuff. Make a range table to stick on your rifle. Laser the range, look at that table, set the sight aim, hold still . . . You know the rest of this story.

Local shop has some of thos sigs In stock, if i didn't already have the gforce1300 id take a hard look at them. They are about double what i paid for mine, but the guys at rhe shol were getting hits at surprisingly long distances.....all fairly reflective targets tho.

My buddy has a leica that while pricey is head and shoulders above any of the other range finders ive gotten to play with...no swaros yet.
 
For reference the Sig Kilo 2400 ABS outperformed the following LRFs in testing, on the hardest to hit target (2.5' x 2.5' 20% Reflectivity):
Nearly Identical to the Vectronix Terrapin
10% Better than: Steiner Binos & Leica Geovid
20% Better than: Leica 1600
30% Better than: Sig Kilo 2000
50% Better than: Gunwerks G7 BR2
70% Better than: Bushnell Elite 1 Mile, Vortex Ranger 1500, SilencerCo Radius.

Very neat looking product there, far more than i in all likelihood will need, but excellent features for those that will use them.
 
I'm rather partial to the Leica RF. You can find used ones in excellent condition for ~US$600. I also like the Leupold and Vortex ones as well, and both companies offer excellent warranties.

Cheers,

1)FWIW, Cabelas has the Sig Kilo 2000 on sale for $350 right now. It doesn't have a built in ballistics computer.
2)I'm not a smartphone guy, but I bought an android Moto E on closeout somewhere for $20 to use a ballistics app. I like the notion that I can try different ballistics apps, or adopt new ones if they seem better.
3)I have a Kilo 2000. I'm no expert, but just walking around pointing it at trees or whatever it pretty reliably reports ranges out to 1000 yards or so. Past that it depends. I haven't spent a lot of time playing with it, so take this with a grain of salt.
 
one thing i forgot to mention about the gfx1300. While dosent take into account atmospheric conditions, with the drop tables as long as you know what your rounds will do at the correct altitude and envi conditions you can pick the correct one to use bassed on conditions. While not nearly as good as one that allows the inputs, or a secondary balistic program (which can be used to adjust for envi, and then help chose the right drop table), they are quick and affordable. I played with my .458, nikons spoton, and the bushy drop table that corrisponds with it at sea lvl, and it was pretty close out to 350ish which is a lob for a slow .458 bullet

using a ballistic ap to proof the drop table should work pretty well for any range finder that has options for that.

Again not as good as a point a click but should be workable for most conditions.
