laser rangefinder

[people]

Your comment is so childish, it just reflects on your lack of maturity and credibility.

I am not in politics, and I work as hard (or harder) as anyone else - if you don't like your job, or the number of hours you work, or your life... it is not my problem, nor relevant to this topic, so please stop whining for pity, because it clouds the discussion and makes you sound pathetic.

I will explain, since you obviously do not understand what you are talking about - though I think you shouldn't get into technical discussions on subjects you know nothing about.

1 - A laser rangefinder sends a beam out, and then "listens" for the return, like sonar. It measures the time, and computes the distance to what the beam was reflected from.

2 - the beam has a finite diameter - like a flash light. It is brightest in the center, and gets dimmer as you get further from the center. The diameter of the beam is measured at the "3-db down" or "Half power" points (they are both the same).

If a beam has a diameter of "2", it's actual diameter might be 4 or 7. THis extra diameter is called "spill".

3 - To us, grass and other chlorophyllic plants look dark... but the IR beam's wavelength, they are chalk white, but furry little animals that look brown to us, look almost black to the laser.

So, no matter how much you spend, or how much power your laser has, when you ping a woodchucks head in an alfalfa field... because of the "spill", you will get reflections from every weed and blade of grass in the area, since, at 400 to 800 to 1,200+ yards, the beam is 4 to 20 times as large as the woodchucks head, and you have no way of knowing what is giving you the ping return.

Commenting on ranging an antelope at 400 yards is meaningless, because it is not on the ground, you are pinging it broadside, and it is huge in size (compared to the beam size).

This is why guys that actually use lasers on small animals like PDs and 'chucks, (instead of reading catalogs) will tell you that the lasers have a lot of problems ranging small animals across long, flat fields.

Now, go get a job you like.

Wow catshooter I expected nothing less from you but personal attacks on me for bringing up facts that are true.

Did I say anything about my job? What about what I do? What about what I make? Even how many of the guys here on this fourm have bought my products? Have I EVER stated what I make? NO. So why are you talking about my job? Are you delusional? Did I say anything about antelope?

Did I say you were in politics? Maybe re-read what I had typed out since you missed what I said. Incase you do not want to re-read it I said you remind me of a career politician.

Again re-read what I had typed out. So you are saying no matter what you spend all the laser beams are exactly the same? What I am saying is if you spend more beam confinement is better.

Yup... the civilian lasers have almost the same beam sizes - plus spill.

... and "whatever" to the rest - you are debating something you know nothing about... not even the basics!

 

[mshelton]

I don't know what the "beam confinement" specs are on this model but I was fortunate enough to get to play with one on a groundhog hunt once. Unfortunately it wouldn't pickup hogs poking their heads up in an alfalfa field from 600-1200 yards, even had it on a tripod.

Like I said, I don't know the specs but at a $19k list price they are probably a little better than my Zeiss PRF and my friends Swaro rangefinder. The coincidence range finder had no issue and at less than $600 for the Swiss unit, I'm gonna go out on a limb and say Catshooter was right in his statement about money not mattering in this situation.

But hey, if you're in central VA, please continue to use the laser rangefinders on those long hogs, means more for me and my friends, just try and not educate them too much while you're missing.

See what that so hard? Was that so hard? More cash equals better optics thus less spill or better beam confinement. You make stuff way harder than it needs to be.

As to the rest of lasers I do not need to know I only need to know how to employ them. And yes more expensive is better than cheap ones.

 

[Hydenseek]

If a groundhog sticks his head out at 900 yards and you know how far he is to the inch, what's hard about that is finding someone that makes consistent first shot hits, especially head shots.

" More cash equals better optics thus less spill or better beam confinement. "

I did NOT say that. Spill has nothing to do with "better optics".

You keep making stuff up. Why don't you get off of your butt and go out and use 2 or 3 different lasers in the fields for a summer.

You remind me of high school kids that "debate" the performance of muscle cars, but don't have driver's licenses.

Hey Cat did you ever use a Terrapin? I bet not. If that's the case you can't comment on it. I have never had a situation where it couldn't range. It blows the rest of the laser rangefinders out of the water. I have used mine going on three years and ranged hundreds of times, maybe even thousands. It has never failed except when really foggy. Then you couldn't see to shoot far anyhow. Unfortunately they quit making them. Said they couldn't make enough money on them. I believe the reason is because they worked that good they couldn't sell their really expensive ones. Matt

 

[JamesnTN]

I know for a fact a friend of mine has a Terrapin and ranges cow patties at 1600-1800 yards with ease.

No... but I own an AN/GVS-5, which will read to 10,000 meters (6.2 miles) under the most worst conditions (flat black target, in high noon sunlight).

It will pound a terrapin into the sand... but it will not ping the head of a 'chuck peekin' out of the alfalfa at long range, or PDs at equally long ranges...

... and neither will any of them - they are not designed to range targets that small at long range. Guys buy a Leica 1,600 and say, "Wow, man, I ranged a house at 1,600 yards!"... well, big deal, do they shoot houses? Go range a beer can at 1,000 yards - whoops, that is not in the manual

Get an 8" tall, dark brown fuzzy toy animal, and put it on a beach, in the sand. Then drive up the beach 1/2 mile way, and ping the little animal (IF you can even see it)... you can't get the same reading twice... and it will not be close... if the reading sayd 875, do you know it is 875 (or whatever).

I'm serious - try it.

I can get 20 readings in a row, all within 20 feet.

it is easy when the animal is across a dip in the land, on the side of a hill, but then, you are ranging the hill, not the animal...

If "Big lasers" were the end-all solution then there would be no one using optical range finders.
I have a "Very big" laser, plus two Bushnell "sports' level lasers.

And I have two large optical rangefinders - a Wild, and a Swedish Periscope. I wouldn't hump those bigassed rangefinders, if the big laser could do it all.

But none of the lasers, (Terrapin or AN/GVS-5, or any of the others) can range a 3" wide dark animal, peeking out of grass or alfalfa at long range. They do not have the aiming capability.

The Terrapin has a 5X - and an "area" to aim in - the beam is "somewhere" in that area, but rarely in the center. They are designed to range large game, or small game at 200 to 300 yards - but at those ranges, who needs a range finder with a flat shooting varmint rifle.

So they don't work for the kind of targets this thread is about.

A cow pie, with a 5x scope, at over a mile... wow, I AM impressed!!!

Oh-My-Gawd....can you people just give it a REST?

Some of you people just like to argue...plain and simple. Arguing for the sake of arguing.

Please go do it somewhere else....

 

[mshelton]

A 1700yd cowpie shot would be right.

Catshooter you are a liar. Hold on let me say that again. You are a LIAR. Did you get that? You are just like a politician where you can not listen to what I have to say.

Before I get too far into this do you even have one of these 20k range finders? If so post up a picture of it in your left hand.

So there are no optics in these range finders besides what you look through? So it is just a piece of plastic or class to prevent the laser from getting dusty? No there are optics you look with and there are optics for the laser side.

Get off my butt? Go back and get some info on what I currently own.

I have two of them and have used them extensively that is why I know you are wrong. Who reads catalogs?

Again just like a politician you have to toss out your own little stories about highschool boys instead of actually listening. You just have to be right no matter what.

Poodle-fight re-direct : why not recconoiter the damn prairie-dogs by fire, with a spotter to call the shot. spend 50 cents, walk the next one in. or drop 20 K hero-style and impress who ? or screw the laser deal, just use Google earth. or just step it off. armchair prairiedog commandos gotta stay in shape, and last I heard they don't bite. by the time you get back to the FP they will be back up..
