Welcome to PNL Testers - Your Archery Data Specialists
At PNL Testers, we focus on physics-driven archery research using real measurements, controlled testing, and transparent data. Our goal is to help archers understand arrow stability, drag, accuracy, penetration physics, and bow efficiency using proven scientific methods, not folklore or personal opinions.
All research includes charts, raw data files, velocity logs, and fully repeatable testing procedures.
Penetration Mechanics – Physics-Based Series
A complete, physics-based model explaining how penetration works in any medium.
Covers kinetic energy, resisting forces, geometry, deceleration, and structural stability.
This is the full universal framework that all PNL Testers penetration research is based on.
Penetration Mechanics: A Force-Based Perspective
A plain-language explanation of the same physics framework.

Real-World Testing & Field Experience
We combine controlled lab testing with real hunts and 3D shooting. The photos below are from field setups we’ve tested—so the data you see on this site reflects how arrows actually behave in the real world.
What We Test
-
Arrow stability, rotation rate & recovery distance
-
Form drag (Fd), drag coefficient (Cd) & aerodynamic efficiency
-
Velocity loss over distance & time-of-flight
-
Precision (mean radius), repeatability & shot consistency
-
Static spine
-
Blade edge sharpness (BESS) & cutting-edge performance
-
Bow mechanical efficiency (stored vs delivered energy)
-
String performance – verifying whether strings actually increase mechanical efficiency or only restore lost speed
Beyond the Ordinary
At PNL Testers, we move past opinions and folklore by relying on real measurements, controlled testing, and physics-based analysis. Our research is designed to be transparent, repeatable, and useful to everyday archers as well as advanced shooters. We focus on data that matters, stability, drag, accuracy, and performance—so you can make informed decisions backed by science.
