ATN Auxiliary Ballistic Smart Laser Rangefinder w/Bluetooth

Good quality(what you would expect from a extremely expensive optic and addon) it syncs up with the scope every time and after measuring the distance on a tape measure it's only off by 1 yard or so, which is Definitely not a huge difference for me just going to a range and not using it for any hunting. It's a must have with your xsight4k IMO as it does 99% of the sighting in for you if you have it

This was a perfect pairing with the x-sight 4k pro I purchased. Excellent quality, easy add-on,and makes a huge improvement on accuracy with the simple push of a button. Highly recommend this product.

Talk about being spoiled... I mainly hunt whitetail and this accessory for the ATN is one of the coolest things I've ever bought. I picked up an ATN X-Sight 4k Pro 3-14x 2nd hand and love it. As soon as I decided to buy the scope I started research and saw this range finder. Bought it before I even had the scope and put it on immediately after purchase. The whole setup it damn heavy, but it's worth it to me, and I still hunt 95% of the time. Hitting a button to get the range and the ballistics being calculated automatically...? No more clicks on the scope for long shots...? Money. I haven't tested it at ranges over 200 yet (not shooting anyway), but when I do, I'll update my review. If you have the money, get this thing.

its not a perfect world but it does function well ..useful info thats not widely available - you really cant see the zeroing lazer through the thor, you put it on a known target spot 'then' zero the rangefinder reticle you see in the thor screen to that same spot ...next point of interest - the rangefinder reticle is completely seperate from your gun sight reticle ... in other words they dont line up, so when you use the rangefinder, youll move the gun to put its reticle on you target ... this can be a big issue if it winds up being zeroed way off from your gun sight reticle, youll have to swing the gun way off target to range .. this is why i gave it 4 stars .. you can shim by trial and error to get the reticles closer but theres no built-in way to do it ..its a pita..other than that, once you got it dialed in it talks to the ballistics app no problem and works well ...just realize the above two points go unsaid and are something youll be dealing with ...*update* - after using 2 units for a couple of months and loving them, i ran into an issue with both, one on a thor4 and the other on a 4kpro, so its not the scopes, its the abl ...the first unit became dead and wouldnt connect and atn replaced easily enough, kudos to them ... then the second unit died, and after reading other reviews it seems its not uncommon ... where the problem begins is if the battery goes too low or gets dead in the unit and its either left on or turned on to the low voltage .. it scrambles it and it will no longer connect ...this is a serious problem, all it takes is one time forgetting to turn it off or leaving it in storage for awhile and the batt goes real low and you turn it on - dead unit, rma time ... theres no warning in the manual about this .. the best strategy from now on is to turn off the unit and REMOVE the battery after each use and be sure to install one above spec voltage before use .. every time ... may not apply to all units but both of mine fritzed on me ..waiting on the second rma unit ..

I purchased this rangefinder to pair with my X-Sight 4K pro. It worked perfectly and was easy to set up. I sighted my .223 rifle in at 25 yards with the one-shot option in the x-sight scope menu. After one shot, I was MOA at 100 yards, 75 yards, and 50 yards with the rangefinder adjusting point of impact with the press of a button. Truly amazing.Pros:Quick, easy setupExcellent Build QualityWorks exactly as describedVery AccurateCons:Button placement- to activate the rangefinder there is a small button which is on the rangefinder at the front of the scope. If you need to make a quick adjustment in a high stakes shot, reaching for the front of the scope is a pretty big motion to manage. I purchased the ATN X-TRAC tactical remote which can be placed anywhere on the rifle via Velcro straps and controls both the rangefinder and the xsight menu controls. The trio combine for a powerful setup that you won't even find in high-end night vision or thermal scopes.Size- when added to the already large X-Sight scope makes for a very large optic setup.That being said, I am mainly hunting predators from a fixed position. I am not sure the xsight plus rangefinder combo would be very comfortable to carry or shoot out of a cramped deer stand. I can be done, though.

It mounted easily, I was a little confused about the rubber O Rings and where they went but figured it out. I took it to the range, aligned and calibrated it, and it worked great! I 3D printed a cover to protect it. I find that my lens covers no longer fit so having a 1/4" relief around the tube extension so you can use the aftermarket flip-caps would be nice
