About – Universal Marksmanship System
The problem
All scoped firearms require precise calibration to align the barrel and optic to the same point—a process known as boresighting. Mainstream boresighters, including collimators and lasers, have seen little innovation since the mid-1990s. These manual tools are designed to get your first round on paper but require ideal lighting, a known distance, and a gun rest. If a scope is bumped or compromised, recalibration can take up to an hour.Manual methods lack the ability to collect, store, or verify calibration data—making it impossible to recall zero later. Worse, many boresighters are misaligned—left, right, high, or low—leading to time-consuming corrections and wasted ammunition.
The solution
Zero Verify is a patented digital boresighting and zero verification system that combines a smartphone application with strategically positioned sensors along the line-of-sight and line-of-bore. The smartphone becomes a smart boresighting tool. It knows if it’s tilted, shaken, or off-center. It tracks what your scope sees and how your reticle moves. Then it tells you — clearly and precisely — how to adjust your crosshairs so that it lines up with your barrel perfectly.ZV uses a trigonometric method to synchronize the coordinate systems of the barrel and scope, linking directly to the app. The app computes a point onscreen—a red dot the user manually aligns the scope crosshairs to intersect. Users can create custom profiles, perform boresighting, and record calibration settings after physically zeroing at the range. Later, they can verify zero without firing a live round—even if conditions have changed.
The system supports a universal mounting kit compatible with most firearm and optic combinations—military, sporting, and tactical.
Research and Development
With seven granted patents and over a decade of research, Zero Verify is the first boresighting solution to leverage both smartphone technology and embedded sensors.Founder and CEO Selso Tello’s pioneering work has resulted in a highly disruptive system—validated through simulation modeling, physical testing, prototyping, and comprehensive patent development. Selso continues to lead R&D, bringing engineers, database architects, and app developers into the fold to advance ZV’s capabilities.

ZV PRO – App Functionality
Four App Functions
1. Boresight
ZV establishes an initial alignment point—a red dot—where the optic and bore are visually aligned. The camera streams the sight picture to the smartphone app, and the user adjusts the crosshairs using elevation and windage turrets until crosshairs intersect with the red dot on screen.
2. Record Zero
Once the shooter has physically zeroed the firearm at the range the point-of-aim and point-of-impact intersect in the sight picture. The app then captures and stores the crosshair position for future recall.
3. Verify Zero
Users can recall their saved zero and adjust turrets back to the red dot in the app. This feature enables verification anytime the sighting system has been compromised or when operating in a new environment with different weather or elevation. Verification allows rapid optical adjustments without live-fire testing—saving time, conserving ammunition, and ensuring optimal performance across conditions.
4. Predictive Zeroing
This advanced feature goes beyond mere verification by calculating and applying corrections based on changing environmental variables. ZV analyzes historical alignment data and ballistic models, incorporates updated environmental inputs, and runs calculations through an AI/ML predictive engine to generate a corrected aim point—ready for user adjustment.
Data – Data Lake and Predictive Zeroing
Zero—or final weapon calibration—
encompasses all variables and constants that influence a projectile’s flight. Constants include shooter expertise and the equipment manufactured tolerances. Variables present during zeroing may include weather, temperature, location, and weapon performance. This data can now be collected and stored in the cloud, much like water accumulating behind a dam—steadily building volume over time. From this reservoir, information critical to marksmanship, marketing, and research can be extracted, analyzed for trends, patterns, and correlations, and processed through AI-driven engines to deliver actionable insights. The result: enhanced precision, improved readiness, and a smarter path to operational superiority.ZV LITE
Zero Verify Lite is ZV’s minimum viable product (MVP)
The smartphone acts as a digital collimator mounted to the muzzle end of the barrel rather than the scope. It enables users to boresight, record, and recall zero settings—just like the more advanced ZV PRO—but without AI or machine learning for predictive zeroing.
Setup includes:
The ZV App with a digital grid and a smartphone barrel-mounting system. ZV Lite relies on the phone’s internal sensors to detect line-of-sight and line-of-bore, with additional user input required for calibration.
R&D — Technology Validation
SolidWorks 3D Virtual Simulation
Johnathan Boyer of Aztec Engineering developed a 3D simulation and virtual prototype of ZV PRO and ZV LITE using SolidWorks—a powerful modeling platform capable of virtually prototyping any physical system. He successfully modeled a riflescope at a 25-yard range, simulated precise adjustments using trigonometric calculations without live fire, replicated a scope bump and corrected it via proximity sensing, and created a digital twin that linked the coordinate systems of the rifle and scope to the smartphone using a pixel grid within the app.
Physical Testing
Testing replicated real-world target practice conditions using a simulated smartphone application. A physical smartphone served as a stand-in for various sensors and digital devices, collecting live data instantly and feeding it into the app. In the final product, the smartphone will perform all necessary computational functions and generate outputs for sighting in the rifle at the desired range. During testing, the phone provided the required sensor inputs for boresighting, while calculations were executed on a separate laptop.
Observed Outcomes
Scope adjustments made during testing matched predicted shot deviations from the simulation, validating the underlying computations. Testing confirmed Zero Verify’s ability to predict mean point-of-impact and support repeatable sight adjustments under controlled conditions.
IP — Extensive Patent Protections

Licensing – Zero Verify: A Licensing Opportunity in Precision Firearm Technology
Technical Differentiation
ZV aligns with key market trends and sits at the intersection of sensor fusion, smart optics, and adaptive fire control. Zero Verify is a patented, sensor-driven system that transforms how shooters boresight, record, and verify zero, and predict zero shifts — functions that remain fragmented or absent in current boresighting tools and smart optic systems. By triangulating the line-of-sight and line-of-bore, Zero Verify delivers precise point-of-aim alignment across a wide range of firearm and scope combinations, without requiring investment in new optics or firearms.All boresighters reference the chamber. Zero Verify marks the projectile’s actual departure point with a sensor—enabling accurate line-of-bore detection and scope height measurement without manual estimation. Even as optics become more sophisticated, no scope physically references the firearm’s line-of-bore to determine sight adjustment. Zero Verify fills that gap—offering a defensible, licensable enhancement to both legacy and next-gen platforms.
