Rangefinder on Airgun.

Like most folks here I use a Nikon or Leupold rangefinder that I keep in my pocket or around my neck and it’s basically a pain when ya need a quick yardage reading, while surfing around the other day I came across this Laserworks Rangefinder so I looked some more for reviews and it seems it has more better reviews then poor, the price seemed right so yesterday I ordered one to try on one of my go to airguns and I might even try it on one of my crossbows and powder burners, here it is the Laserworks.

Very interesting all you need is scope tube adapter to weaver picatinny on all of your guns so you can easily use that one device for all of your guns.

That’s what I’ll be doing, had one for my AR’s but bought another one with inserts so I can use it with 25.4 or 30mm scope tube, if it’s any good I’ll pickup another one.
 
Very cool. But i have a question. How do you know its actually ranging what your looking at through the scope? Or do you always use the iron sights on the unit itself?

Good question and from what I’ve read you zero it in to your scope, it takes a bit of work to get it so where the laser hits and reflects back is the same as your crosshairs on the scope, seen a video of where it is done with a pulsar 550 at night and you can see the laser hitting the target and then you can adjust the scope crosshairs to the spot the laser is hitting, looks real easy with a night scope. I think I’ll have to set up a small 15” target at 50 yards then put the airgun in a solid benchrest so it doesn’t move and get the laser to hit it and see where my scope is, using the open sites on the laser body will held but don’t know how accurate they will be to the laser. I’ll post on how hard it is to do later, maybe it’s not as hard as they say.

It should be here today hopefully but it will be awhile before I can really check it out being I find out tomorrow when my heart surgery is going to be, seems I need a new pacemaker, the one I have now is failing at keeping me out of AFIB but once this is all done with hopefully it will still be somewhat nice out or I might get it done on a different airgun before I have surgery.
 
Its not hard to get the laser rangefinder calibrated to your scope. Easiest way it to set something like a small box (12"x12" or similar) on a stool or something in a field or lawn where there is nothing else around, at about 50 yards. This way you know when you put the crosshairs on your scope in the middle of the box and then adjust the scope mounted laser so that it gives you a good yardage (that you know from using your handheld rangefinder). Just adjust it until the range is correct and then move it left and right, up and down to see where you need to be so that the rangefinder beam is in the middle of the box. Takes less than 1/2 hour the first time. After that its much easier...
 
Thanks Centercut 👍, you explained it better then I did but that’s what I’m going to do, I’m not to good at explaining things, guess that’s why I don’t teach 😁. Anyway here it is. I have a Mega Marine coming from Troy when he is done tuning it in a few weeks so I think I’ll wait and set it up on that airgun then I don’t need to mess around sighting it in again.

I dont see how this would work over long distances. If you mount this over your scope there will be ranges that the path of the laser is off by a decent amount from the reticle of the scope. It might be fine for closer ranges from 20 - 50 yds but farther distances wont be accurate. If you mount this over your scope you will be apprx 2" or more over the scopes sight path. If you adjust the laser to be on the same point as the scope at 30 yds then move out to 100 yds the laser will be pointing lower than the reticle is at 100 yds. The point before the 30 yds the laser will take the reading above the reticle and after 30 yds it gets increasingly lower than the reticle as the range increases. I will use my wolverine .25 as an example. My scope is sighted for 50 yds so I would set the laser rangefinder to be exactly on my reticles point of aim at 50 yds. Sounds fine at this point right. If I move out to 100 yds my wolverine has a drop of 12.47". So if I aim at an object with my scope and its 100 yds away the laser rangefinder is going to be pointing beneath the reticle by a large amount and give me an incorrect distance. At that kind of distance if the reading is off by just 2 yards my impact will be 1" low. It will be even more problematic if theres an obstacle between you and the target cause it might give a reading from the top of a bush 15 yds closer than the target. It would work better if its inline with the sight path of the scope for vertical alignment and just slightly to the side of the scope. 
 
I’ve used mine and never ran into that problem. Light doesn’t bend like a pellets flight path. If zero at 50 it’ll be 2 inches high at the muzzle and two inches low at 100 yards. More than close enough to get a good range. After that you use your holdover to get the right pellet flight path to the target. Make sense?
