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.

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.
