Vortex Optics Impact 4000 Ballistic Rail-Mounted Laser Rangefinder

The product matches the description. Good quality product. I recommend for purchase. The seller sent the goods quite quickly. The parcel track was tracked all the time. It's very convenient to shop through Amazon.com

This thing straight up works! A little tricky to calibrate at times but worth it once you get it set.

Easy to calibrate, mount, and zero.It's an all-in-one ballistic solver and range finder. Good data in will put out good data. Used it up to 1200 yards on a UKD range and was able to score hits on every target as long as i had a stable firing position.Use with Geo Ballistics app on your phone (it automatically unlocks premium version when you connect your Impact 4000 the first time) or use it standalone and get the same amount of features.Only complaint is that it's not QD since you have to recalibrate if you take it more than 30 miles from where it was calibrated last. If you want full use of the solver. If you're just using for range (Idk why you would), then you don't have to worry about it.

This item came in an open box and was advertised as new. The remote was not connecting properly and signal was being interpreted. Condition was not new but it was used if you see the mount, you will see. Please advertise products properly and request immediate refund.

Love it

Best WMLRF in this price range, highly recommended.For those on a budget, there a few other less expensive options out there.1 yr update: Compass calibration is one area that could be improved on this product, it's a bit too time consuming. Some are having trouble completing the calibration process. Maybe a new firmware release will fix this. I've actually moved away from this in favor of a Sig Sauer KILO1600BDX combined with a Sightlok RF-1 mount, saving $1600 for better overall performance and functionality.

This is a fantastic device for long range shooting. It’s a range finder, ballistic calculator, & weather station all in one package. It is very accurate assuming you enter in good data about your rifle, optic, & loading. It’s no different than any other data collection device. You get out of it what you put in. If you don’t know load velocity, projectile length, twist rate, optic height, etc. then you are not going to get accurate shooting solutions. However if you know your data and enter it accurately this device will greatly increase your first round impact capability out to 2000+ yards. Of course wind is always tricky. It will give you accurate data at your location but the wind could be doing something different 1000 yards away. All in all this is a wonderfully convenient package.

Only to things I don’t like are the size (it’s a little big) and compass calibration, which is a huge pain in the a**. Other than that, it’s been fantastic. Have ranged in broad daylight out to 3800yards. Dope has been dead out out to a mile this far. And it’s pretty easy to setup and use. Recommend in for sure
