PNL Testers – Archery Testing, Arrow Physics, and Performance Research
PNL Testers provides independent archery testing and arrow physics research using real measurements and controlled methods.
Our research focuses on arrow stabilization, drag, velocity loss, penetration, and Front of Center (FOC) to understand how arrows behave in real-world conditions.
All results include raw data, charts, and repeatable testing procedures.
Penetration Mechanics – Physics-Based Series
A complete physics-based framework explaining how penetration works.
Covers kinetic energy, resisting forces, deceleration, and structural response.
This framework forms the basis of all PNL Testers penetration research.
Penetration Mechanics: A Force-Based Perspective
A plain-language explanation of the same physics-based framework.

Real-World Testing & Field Experience
Controlled testing is combined with real-world hunting and 3D shooting.
The data shown reflects how arrows actually behave outside the lab.
Field results are used to validate controlled test data.
What We Test
- Arrow stabilization, rotation rate, and recovery distance
- Form drag (Fd), drag coefficient (Cd), and aerodynamic efficiency
- Velocity loss over distance and time-of-flight
- Precision (mean radius), repeatability, and shot consistency
- Static spine and structural behavior
- Blade sharpness (BESS) and cutting-edge performance
- Bow mechanical efficiency (stored vs. delivered energy)
- String performance and its effect on mechanical efficiency
Beyond the Ordinary
PNL Testers focuses on measurable, repeatable results using controlled testing and physics-based analysis.
All research is designed to isolate variables and provide clear, data-driven conclusions about arrow performance.
