ATNAuxiliary Ballistic Smart Laser Rangefinder w/Bluetooth

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.

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 is a brand new product offered by ATN for their premium scopes. I was excited to receive one of the first units to hit the North American shores and quickly attached the unit to my X-Sight 4K. The physical attachment was as easy as pie and took a whopping three minutes. The bluetooth connection took a bit longer. At first, the unit would not pair with scope after about twenty attempts. Finally, it did indicate that it was paired, but the unit would not allow me to align it using the built in laser. It simply came back with a message to connect the ABL. After checking for a new firmware update at the ATN website, the new version 330 was found and I installed it into the scope. After a few more failed attempts, it finally acknowledged the BT pairing and locked the two units together. The rest of the setup proceeded without any issues and it is now a fast and accurate scope system. I have yet to take it to the range, but I have verified its readings with my Leopold rangefinder and it is spot on. What a wonderful, accurate system! It's a keeper.

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 ..

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.

This ABL rangefinder works great with the X sight Pro 5-20X. Very accurate and easy to use. Makes the ballistic computer accurate over long distance by using exact sight-in target distances. I Did not realize how sight-in target estimation ruins ballistic correction factors. WOW! You are wasting ammunition $ if you don't own one of these!!Not sure why, but it seems to want to work to 1500yds even though it is spec'd to 1000 yds.
